Resumen

Early-age moisture loss from the surface of a concrete pavement may induce undesirable effects that play a factor in long-term performance. Early-age detrimental behavior such as slab curling, warping, delamination, and even plastic shrinkage cracking are affected by the amount of evaporation and the effectiveness of the curing medium. The rate of evaporation is a key item in the monitoring of the quality of the curing. However, most approaches for this are largely empirical and are useful only under laboratory conditions. The effective curing thickness concept is introduced as a method to evaluate the effectiveness of a curing method. The surface relative humidity has the biggest influence on both the effective curing thickness and the rate of evaporation. Thus, prediction of the rate of evaporation of the water from concrete depends on the relative humidity of the surface and is important for evaluation of the curing method. Existing evaporation models, including the American Concrete Institute nomograph, were evaluated for their capabilities in predicting evaporation from curing concrete. Data from a series of laboratory experiments with a modified version of Penman’s evaporation model are also presented.

Resumen

Abstract: Efficient uninterrupted curing is a key to quality concrete. Proper curing of concrete is crucial to obtain design strength and maximum durability considering the cost of curing. Curing is designed primarily to keep the concrete moist, by preventing the loss of moisture from the concrete during the period in which it gains strength. Due to rising problem of scarcity of water and expensive conventional methods of curing, it had become necessary to build-up a new method for concrete curing. This paper represents the experimental work related to a newly developed, effective and economical method of beam curing. This method consists of a technology namely ‘Curing Pad’ that not only absorbs and retains water for an extended period of time but also reduces evaporation losses. Concrete pad consists of 3 layers. The top layer is of a reflector material that reduces evaporation losses. The middle layer comprises of an absorbent material that stores and transmits water to the concrete beam. Bottom layer is binding or packing layer that holds all three layers together. Various tests are performed to check the durability of Curing Pad as well as its performance on concrete beam. These test results are compared to those of ponding method of beam curing.

Resumen

Guangxi province is the typical expansive soil area, and the unconfined compressive strength is the important strength index. There is little studied result about the unconfined compressive strength of expansive soil in Guangxi province. Based on the expansive clay experimental embankment of Nanyou Highway, the experimental research on the unconfined compressive strength was undertaken. Tests results indicate that the expansive clay samples are all disintegrated when the sample is dip in water, which show that the stability of expansive clay is very weak. Some lime improving samples of curling 7 days and 14 days are also disintegrated when dipping in water, which indicate that the unconfined compressive strength sample of lime improving expansive clay should curl 28 days. Lime ratio and curing time both influence the unconfined compressive strength of improving expansive clay greatly. There is optimum adding lime ratio for lime improving expansive clay. During the early days of curing the unconfined compressive strength have linear increase with curing time.

Resumen

Objectives: To measure and compare the bond strength between three different types of ceramics and resin cement, as well as the degree of conversion of resin cement after using different light-curing units and curing modes. Methods: Three types of ceramics—Leucite-reinforced (Empress CAD), Lithium disilicate (Emax CAD), and Zirconia (Emax ZirCAD)—of varying thicknesses (1.5 mm and 2.0 mm) were bonded to a light-cure resin cement (Variolink Esthetic LC). Light-curing was carried out using a monowave LCU (3M Elipar DeepCure-S LED Curing Light with irradiance of 1470 mW/cm2) and with polywave LCU (Ivoclar Bluephase PowerCure) using High, Turbo, and 3 s curing modes, respectively (1200, 2100, 3000 mW/cm2). A chevron-notch bond strength test (total n = 288) was conducted to calculate the fracture energy and interfacial bond strength (J/m2). The degree of cure (%DC) of the residual resin cement on debonded surfaces was measured using Fourier Transform Infrared Spectroscopy (FTIR). Collected data were statistically analysed under SPSS ver. 27 by conducting an ANOVA and Bonferroni post hoc test. The mode of failure was established using a scanning electron microscope (SEM). Results: A significant difference in interfacial bond strength was found between the three types of ceramic material groups (p < 0.01). Cement cured through Empress that was 2 mm thick showed the highest bond strength (1.36 ± 0.46 J/m2), while the lowest was observed (0.26 ± 0.07 J/m2) in 2 mm Emax CAD using the 3 s mode. The use of different LCUs and curing modes had a significant influence on the %DC of resin cement seen in all groups, except 2 mm Emax ZirCAD. The dominant mode of failure for Empress, EmaxCAD, and EmaxZirCAD were cohesive, adhesive, and mixed, respectively. Conclusions: The type of ceramic and its thickness can significantly affect bond strength, and the results showed that polywave LCU is more effective than monowave LCU when curing through ceramics.

Resumen

Curing is the process in which the concrete is protected from loss of moisture and kept within a reasonable temperature range. This process results in concrete with increased strength and decreased permeability. Large quantity of good quality water is needed for curing concrete and labor has to be conscious while curing. Curing is difficult when works carried out at heights. Curing can be done both internally and externally. For external curing ponding, wet covering, fogging, sprinkling, etc., can be adopted. Internal curing can be done by adding admixtures in the concrete. In this project, sand is replaced by coir pith for the internal curing purpose. Coir pith can hold water up to 25-40 days. Due to this water holding capacity coir pith is used in agriculture. So, replacement is done for sand by 2%, 4%, 6% and 8% of coir pith in concrete and concrete tests for these replaced concrete specimens are done. Results of conventional concrete specimens and coir pith replaced concrete specimens can be compared and conclusion is arrived

Resumen

In general, steam curing is applied to improve the productivity of precast concrete products. After steam curing, products are stored outdoors for secondary curing before shipment. However, drying shrinkage and microcrack expansion that occurs during steam curing may impede strength enhancement. On the other hand, water curing is also clearly effective as a secondary curing process. However, installing a water curing pool in a precast concrete plant is not easy due to limited space. Therefore, this study focused on water sprinkling curing, which is relatively easy to perform without such restrictions. In this study, the effects of water sprinkling curing on the physical properties of mortar at the initial age of steam curing were investigated from the aspects of materials, mix proportions, curing conditions, and test piece dimensions. The results showed that water sprinkling curing increased the compressive strength by about 10% compared to curing under air. The effect of water sprinkling curing increased as the specific surface area of the test piece increased.

Resumen

This paper discusses how the set gradient in a jointed concrete slab is related to the cracking performance and its effects on fatigue crack model calibration. The role of curing quality on-set and how curing quality parameters are related to the set gradient is also discussed. To assess the impacts of curing practices on the set gradient of a newly constructed concrete slab, a field investigation was undertaken at the Florida Department of Transportation State Materials Office in Gainesville, Florida. This study investigated early age concrete pavement behavior with respect to the development of the set gradient. In this research, four test slabs were placed and cured under different conditions to create different states of stress and creep behavior during and after hardening of the concrete. Early age concrete temperature and moisture history are key factors that affect the slab curling and warping behavior as they pertain to the resulting set gradient. This paper elaborates on the details of the cracking performance data analysis of test data associated with the development of the set gradient.

Resumen

Abstract The carbonation resistance of high performance concrete is closely related to the service life of concrete structure, and is an important parameter to reflect its durability. The carbonation resistance of concrete is influenced on selection of curing conditions greatly. In the paper, based on the common curing conditions, the carbonation tests of high performance concrete under different curing methods and curing time were carried out, and the influence mechanism of curing conditions on the carbonation resistance of materials was qualitatively analyzed. The exponential function expression of curing time and carbonation depth was fitted when curing by wet straws. The results show that: in terms of carbonation resistance, the order is wet straw curtain curing, plastic film curing and curing agent curing, and should be cured in advance. The carbonation depth is effectively reduced by short-term curing (3d) and medium-term curing (7d), but the reduction rate slows down, and 7d curing is suggested. The fitted prediction model is calculated the carbonation depth of concrete materials, and the test results are provided data for the selection of curing conditions and time of engineering.

Resumen

Epoxy resin is one of the most applied thermoset polymers as a matrix for Glass Fiber Reinforced Pipes (GFRP). Curing process of epoxy resin is important for the integrity of the GFRP. The present work has been conducted to determine the proper pre-curing and post-curing temperatures and duration to develop epoxy-clay nanocomposite. During this study a differential scanning calorimeter (DSC) was used to determine the glass transition temperature and hence the degree of curing. Several samples of epoxy were prepared at different pre-curing and post-curing temperatures and durations. Pre-curing temperatures ranging from 80 to 150°C and post-curing temperatures ranging from 150 to 200°C were studied. The results show that the optimum pre-curing and post-curing temperatures are 100 and 170°C, respectively. Regarding the effect of curing duration, several specimens were prepared at the same pre-curing and post-curing temperatures with different curing durations of 1, 2, and 3 hours. It was observed that beyond one hour curing, the changes in the Tg and the degree of crosslinking were negligible. Using these optimum conditions samples of epoxy-clay nanocomposites were prepared using ultrasonication. The results showed that the addition of nonoclay to epoxy resulted in a reduction of the Tg.

Resumen

With excellent damping capacity, growing interest has been focused on polymer concrete (PC) as a novel machine tool bed material in the field of ultraprecision machining. It is widely acknowledged that the fly ash (FA) is an essential component material in reducing the curing shrinkage of PC, which can significantly affect the curing characteristic of PC. However, the effect of FA on the curing characteristic of epoxy resin is not studied in detail. In this article, the effect of FA on the curing characteristic of epoxy resin was examined by differential scanning calorimetry. Experimental results show that the peak temperature and curing rates of epoxy resin/curing agent and epoxy resin/curing agent/FA increase with the increasing heating rates, and the peak temperature and curing rates of epoxy resin/curing agent are greater than that of the epoxy resin/curing agent/FA with the same heating rates. In addition, the difference between the maximum curing rates of epoxy resin/curing agent and epoxy resin/curing agent/FA decreased with the increasing heating rates. This article can provide technical reference for curing process of PC for machine tool beds and further improve the machining accuracy.

Resumen

The properties of metakaolin geopolymer paste are affected by the alkali concentration, the initial raw materials, solidification process, and amount of mixing water as well as the curing conditions. This study aimed to investigate the effect of curing temperature (room temperature, 40°C, 60°C, 80°C and 100°C) and curing time (6h, 12h, 24h, 48h and 72h) on the geopolymer pastes produced from geopolymer powder. The results showed that curing at room temperature was unfeasible. Heat was required for the geopolymerization process, where strength increased as the curing temperature was increased. Moderate elevated curing temperature favored the strength development of geopolymer pastes in comparison with those treated with extreme elevated curing temperature. When geopolymer paste was subjected to extreme elevated curing temperature, shorter curing time should be used to avoid deterioration in strength gain. Similarly, longer curing time was recommended for moderate elevated curing temperature. The microstructure of geopolymer paste cured at moderate curing temperature showed obvious densification of structure. In contrast, the structure formed was weak and less compact at very high elevated curing temperature.

Resumen

Steam curing is generally applied to improve productivity of precast concrete products. After steam curing, the products are stored outdoors as a secondary curing process until shipment. However, drying shrinkage and expansion of microcracks that occur during steam curing may inhibit strength improvement. On the other hand, water curing is also clearly effective as a secondary curing process. However, installing a water curing pool in a precast concrete plant is not easy due to limited space. Therefore, we focused on water sprinkling curing, which is relatively easy to perform without such restrictions. In this study, the effects of water sprinkling curing on the physical properties of mortar at the early age of steam curing were studied from the aspects of materials, mix proportions, curing conditions, and temperature of water used for sprinkling curing. As a result, it was confirmed that water sprinkling curing at an early age after demolding resulted in a rapid decrease in the temperature of the mortar surface layer. However, it was confirmed that the same conditions were effective in increasing compressive strength.

Resumen

Internal curing has been proven as a solution to reduce early-age shrinkage and related cracking in concrete. Internal curing can reduce the risk of built in stress, cracking, and curling in concrete pavements. However, the benefits of internal curing go beyond just shrinkage and cracking mitigation. Research by the author’s has shown the incorporation of fine lightweight aggregate-FLWA can significantly reduce the risk of deleterious alkali-silica reaction. When the FLWA replaces a reactive aggregate a dilution effect occurs, but other benefits also exist. The curing provided by internal curing can react a greater percentage of cementitious material allowing a reduction in cement and an increase in the amount of binder fillers thereby reducing the alkali loading of the mixture. Additionally, the internal curing was shown to reduce the pH of the internal concrete pore solution and led to a refinement of the interfacial transition zone, possibly due to a pozzolanic reaction. The FLWA provides a porous inclusion which appears to enable a reaction product, similar to ASR gel to form however with limited expansion.

Resumen

Ultra-high-performance concrete (UHPC) is a distinguishing material used in new constructionand conjunction with conventional concrete. However, some issues limit the wider application ofUHPC, such as high autogenous shrinkage, low workability for large-volume production, highcost, and unpredictable peak curing method. This comprehensive study aims to clarify thedifferent effects of curing methods on the strength development of normal concrete and UHPC.The present article reviews studies that used microwave curing, autoclave curing, carbon curing,steam curing, electric curing, ambient and air curing and water to determine their effect oncompressive strength. All the curing methods achieved satisfactory values of compressivestrength. However, it is not practical to specify the peak curing regimes for concrete or UHPCsince the best results need critical monitoring of curing parameters. The time when the samplesare demolded and subjected to hydrothermal and thermal treatments varies in the literature sinceit depends on the binder setting time. That time should be carefully selected to avoid adverseeffects and to maximise output. A combination of these curing regimes could be used together orwith pressure or heat to further improve the compressive strength. In addition to the type ofmaterials used, the curing temperature and duration significantly affect the overall performanceof concrete. This review is expected to guide future research and provide an overview of theresearch field.

Resumen

More than five months of sensor response monitoring was conducted on a single Portland Cement Concrete (PCC) slab test at the National Airport Pavement Test Facility (NAPTF). Reliable data for relative humidity at different depths within the slab have been retrieved. The monitored data also included temperature, horizontal and vertical displacements, and strains at different locations. The completely wet curing method kept the slab flat within that period. However, when the wet curing stopped, the maximum slab curling reached a very high level. Correlations between the horizontal and vertical displacements, and the correlation between displacements and temperature and relative humidity variations are analyzed. The analysis of correlations between slab curling and concrete strains are also presented. Significant findings are obtained and summarized.
