Full textThe reduction of carbon dioxide emissions related to cement production is a key point for industry today. About 60% of these emissions are chemical and issued from a crucial step in cement production: clinkerization. One of the solutions to reduce carbon dioxide emissions associated with concrete is the substitution of clinker by other materials. Since some decades, scientific community is particularly interested to the use of calcined clays (and specifically metakaolin) as supplementary cementitious materials (SCM). The combination of such materials with limestone filler is very promising in terms of mechanical properties. This study aims at demonstrate that the results obtained with a clay composed of illite and kaolinite before calcination are equivalent to those observed with a clay containing only kaolinite. Through a multi-scale approach, this work shows that the use of a pure clay is not necessary. In the case of ternary binders, hydrate assemblage is similar with one or the other clay. Performance-based approach is adopted for the qualification of durability indicators for concrete containing such binders and carbonation of these concretes must be given attention. Results in this study are encouraging and promising for the industrial use of composite calcined clays in cements

Full textThis study is part of the action program of the french concrete industry; it aims finding innovative solutions of concrete with low environmental impact, which allow to get technical and economic performances at least equivalent to those of the traditional concretes. To answer this issue, the study of ternary binders, made of Portland cement CEM I, blast furnace slag and limestone addition, was realized by optimizing the means that are available in precast industry to accelerate their hardening: use of a thermal treatment, use of chemical activators and optimization of the mixture’s compactness. Thermal treatment proves to be the most powerful lever of action. The developed solutions (material and process) obtain a much better economic-environmental balance compared to a control concrete whose binder is composed of Portland cement CEM I

Full textThe self-compacting ability, or ability of the fresh concrete to flow under the effect of gravity without external energy (vibration) is obtained by using more components in comparison with conventional vibrated concrete, including mineral additions and at least one chemical addition of superplasticizer types. The complex interactions between these components leading to the self-compactibility has been previously demonstrated and controlled at the temperature conditions in the laboratory. The objective of this work is to characterize the self-compactibility in temperature conditions prevalent in hot weather situation and to know what are the consequences of these thermal conditions on the properties of the cured concrete. The experimental program reproduced in the laboratory the conditions of hot weather concreting, during the preparation of the mixture and the maturation of control specimens which are usually done on site. The study parameters are the initial temperature of the concrete, the means to maintain the self-compacting ability obtained at a temperature of 20°C (addition of water or overdose of superplasticizer), the conservation of specimens and the concrete design. The obtained results show that the means to maintain the self-compatibility at high initial temperature does not induce significant changes in the concrete compactness. As a result, the properties in the hardened state are equal or better than those measured at 20°C. Conservation of specimens at a high temperature during the first 24 hours which simulates non-standard conditions does not alter the properties. A more detailed analysis taking into account the maturity, the compactness and the characteristics of hydration (amount of hydrates and kinetics) allows highlighting the advantages of using a matrix with a high content of limestone filler. Finally, the results confirm some literature data and show that the effects of high temperature on the properties of BAP are not as detrimental as those obtained on conventional vibrated concrete. However, the existing recommendations for hot weather concreting should always be considered, and the respect of these recommendations makes it possible to avoid excessive delayed strain under loading observed in the case of the BAP incorporating a ternary binder (clinker, limestone filler and slag) when mixed and matured at high temperature

Full textThe potential of activation of a Ground Granulated Blast Furnace Slag has been evaluated into a ternary system comprising of a Calcium Sulfate as major component and a Calcium Aluminate Cement. This system is not well known and the main goal of this study is to determine its main advantages and limitations. From the usage properties point of view, fast setting and initial strengths are governed by the ettringitic binder. Then, and only if the dehydration is avoided, slag reacts. In this case, slag contributes to the increase of mechanical performances at medium and long terms and to limit the expansion under water. From an understanding point of view, the original experimental approach reveals the potential of the slag. It is based on a comparison of performances with different types of curing methods. The potential of hydration of the slag is amplified when the system is dehydrated during a few days and then rehydrated. However, slag contribution is complex to establish because analytical methods to follow-up slag consumption (such as X-ray Diffraction and Differential Scanning Calorimetry analysis) are not well adapted. So, to understand the hydration mechanisms, indirect approaches are used. Semi-quantitative methods by X-ray Diffraction to follow-up the mayenite, calcium sulfate, syngenite and ettringite, ThermoGravimetric Analysis to measure degree of hydration and Mercury Intrusion Porosimetry to identify microstructural changes have been carried. The most important difficulty concerns the identification and quantification of amorphous phases such as slag, C-S-H and AH3. That is why a modelling approach is necessary to understand the role of each compound in the ternary mixture and in particular the obvious contribution of slag during rehydration test. This modelling approach increases knowledge of the physical and chemical phenomena in this ternary binder. It is useful to explain the observed macroscopic properties such as strength and helps to determine the kinetics of hydration in porous environment. Even if this model is still under development, it has allowed identifying the sequences of hydration (ettringitic binder reacts at very initial time, then anhydrite transforms into gypsum and slag reacts at long term) and confirms therefore that the reaction of slag is slow
