Der volle Inhalt der QuelleCompressed earth blocks (CEB) masonry make it possible to build individual houses at a low environmental (and economic for poor countries) cost because of the use of local materials. Moreover, this step has a positive social and economic impact since it supports the direct human work of construction, contrary to the current type of construction based on the industrialization of the material production. Architecture used in CEB construction is adapted to a material which should support only compression stress. This thesis is a contribution to the formalization of CEB masonries buildings design which concerns, until now, only the code of practice. Only masonry behaviour under vertical compression load is analysed. As a preliminary, the CEB which constitute the principal component of masonry were studied. The various compression tests used for CEB were presented and criticized. Compression test on two half built blocks remains relevant. It was shown that three points bending test can also give compressive strength of CEB. The second component of masonry is earth mortar stabilized with cement. There exists very little information on these mortars with strong clay content (between 5 and 20 % and more). An overview of mortar tests able to be used for earth mortar is made and lead to some propositions for future studies. Finally, two types masonry samples were tested under vertical compression load ; 1m2 masonry and three blocks bpnded samples. The Euroeode 6 formula for masonry compressive strength assessment is used and the results compared with our. Experimental data

Der volle Inhalt der QuelleTraditional Compressed Earth Blocks (CEB) in the Republic of Benin have poor mechanical properties, this justifies why people rely on relatively expensive cement blocks; the use of which greatly affects resources such as water and energy. In this work we have proposed ways to enhance CEB properties for eco-construction by adding plant fibers to locally used construction's soils. This strategy makes it possible to value mineral and vegetable raw materials in a field of an activity that is common to a large part of the population. At first, a soil was chosen according to its chemical composition, its physical, mechanical and technological properties. The choice of kenaf fiber for the reinforcement of the mineral matrix isjustified by its excellent specific mechanical properties and its availability at very low cost. The effects of fibers on soil behavior at young age and on the mechanical and hygrothermal behavior of consolidated materials under 5 MPa (pressure applicable with equipment readily available in Benin) were studied for three mass content of fibers relatively to the soil (0.5% 1% and 1.5%) and different lengths (5, 10, 20 and 30 mm). The results indicated a remarkable improvement in the mechanical behavior of kenaf-reinforced CEBs in terms of flexural and compressive strengths and tolerance to damage. The highest results were obtained with 0.5% of fibers 30 mm long. The addition of a binder (3, 5 and 7% of cement) or (3-5% and 5-10% of cement and blast furnace slag mix) allowed an important reduction in water uptake. The best mechanical results were obtained for a biocomposite made up with BAK soil, 0.5% of flax fibers 30 mm long and a mix of 5% cement and 10% blast furnace slag. Measurements carried out in a biclimatic chamber made it possible to characterize the hydric and thermal behavior of the soil-based materials. The addition of a binder decreases the phase shift and increases the attenuation of the material. These different results show that it is possible to produce in Benin with the available equipment, CEB with mechanical and hygrothermal properties sufficient enought for the construction of type R + 1 habitat

Der volle Inhalt der QuelleThe use of new low-carbon construction materials in seismic areas requires the assessment of the structure ductility in order to properly design the building. The lack of accurate structural performance estimation limits the use of green construction materials.A reliable methodology is established for the seismic design of buildings constructed using geo-sourced materials. In particular, a pilot project of compressed earth block (CEB) masonry building in a medium-high seismic hazard zone in Southern France is developed. Starting from the experimental characterization of material mechanical parameters, the seismic design approach focuses on the modal characteristics of the structure, the expected building ductility, and seismic performance assessment in terms of both displacement and force.The equivalent frame model adopted for structural design of load-bearing masonry is validated for two case studies: a rubble stone masonry building and a CEB masonry building. The model validation process consists of the comparison of natural frequencies and mode shapes obtained by both numerical and operational modal analysis. In this context, a measurement campaign provides the structural response to ambient vibrations and then, the modal parameters and structural damping are obtained by structural identification tools. The modal analysis highlights the impact of timber slab stiffness on the dynamic response of masonry buildings. It is shown that a stiffer timber slab with a reinforced topping improves the structural behavior of the masonry structure under seismic loading, yielding to global mode shapes.The stability verification of the building structure at the near collapse limit state is performed in terms of target to capacity displacement ratio, but it is suggested to verify also in terms of force, since it can be more restrictive in some instances and less dependent on the convergence of numerical procedures.The behavior factor in seismic codes for building design is defined for typical construction materials based on damage observation and numerical models. A specific assessment is needed when new construction materials are adopted because building codes provide only boundary values. This thesis proposes a procedure for estimating the behavior factor that is applied to geo-sourced masonry buildings, but it could be adopted for any construction material. The methodology proposed to estimate the force reduction factor, and then the behavior factor, integrates both the seismic demand and building capacity. For this reason, this methodology can be considered as a capacity-demand-based approach. A nonlinear quasi-static analysis is coupled with dynamic analyses and the behavior factor is obtained on a statistical basis. The results are compared with the estimations obtained using demand-based, capacity-based and N2-based approaches. The impact of adopting a three-dimensional building model or an equivalent single-degree-of-freedom system with these methodologies is analyzed.The proposed capacity-demand-based-method provides, with a reduced computation time, a reliable estimation of the force reduction factor, close to the values obtained using the capacity-based-approach applied to a three-dimensional building model that is considered as a reference. Consequently, considering their reliability and efficiency, the proposed methodology for the behavior factor estimation is suitable for professional practice

Der volle Inhalt der QuelleThe present PhD thesis addresses the high temperature behavior of a compacted raw earth material and a cement stabilized earth material, both of which are likely to be used in fire-prone buildings.A complete campaign of laboratory tests was carried out on the two materials. Residual tests, which included mechanical, thermal and permeability tests were performed after slowly heating at a rate of 2 °C.min-1 using an electric furnace to attain temperatures of 80 °C, 120 °C, 200 °C, 350 °C, 450 °C and 600 °C. Then, fire tests were performed, which allowed for the exposure of these materials' bricks to a high heating rate using a mobile gas furnace designed to follow an ISO 834-1 fire curve in order to simulate a real-life fire accident in a building.Besides the effect of the material composition on the high temperature behavior, the effect of the water content on this behavior was also studied after subjecting the samples of the two materials to different relative humidities (RH): dry condition, 50 % RH, 75 % RH and 100 % RH, at an ambient temperature of 23 °C. As a result, the behavior of these materials is better characterized, allowing for a better understanding of real-world applications in a variety of environments.The material's composition and water content influence significantly its behavior at high temperatures. Following the fire tests, the samples were classified into two categories based on their composition and water state: thermally stable and unstable. The observed differences in behaviors have been ascribed to thermomechanical phenomena. They are caused, on the one hand, by the formed thermal gradients induced as a result of the consequent thermal stresses, which decrease as the water content increases, and, on the other hand, by the intrinsic mechanical properties of the materials (which decrease with the water content). These factors were subsequently demonstrated to play a major role in the material's fire behavior and load-bearing capacity at high temperatures, as assessed by mechanical loading of the samples during fire tests

Der volle Inhalt der QuelleIn the actual context of accelerated climate change and increase in global population, the building industry must face crucial challenges: decrease its environmental impact while offering housing solutions for the humankind. To answer it, the development of new bio-based and local building materials appears to be a much-needed ecological alternative to cementitious materials that presents significant environmental footprint. This PhD work aims to develop earth-based blocks with guaranteed mechanical properties in order to build 3-storey buildings. These earths, stabilized using bio-based additions but without any cement or lime, are locally sourced. Therefore, three earths that represent the local variability of resources are first characterised. Then, the rheological behaviour of each type of earth mix is assessed in order to adapt earth mix-design to each studied forming process (compaction, vibro-compaction, casting and extrusion. Mechanical performances at the dry state and in-service life of each earth mix-design are measured for all studied processing routes. Finally, some durability properties of the Britanysourced earth-based materials are described: capillary absorption, erosion and immersion resistance. Obtained results show that produced blocks are as performant as cementstabilized earth materials and allow to consider the semi-industrial development of earth-based blocks fabrication units for structural purpose with limited environmental footprint

Der volle Inhalt der QuelleCurrently, few re-use ways are developed with clay fines from washing units in quarries. However, these clayey fines represent interesting materials for construction domain. This research work aims to develop non-load bearing precast products and to re-use these fines without thermal treatment as for unfired clay products. Two types of precast products are wished: a “heavy” product (compressed earth brick) and a “light” product (tile hemp-clay).For the CEB re-use way, the level of compaction has to be high. Proctor tests have been done to define the moisture content and dry density to obtain. Mechanical performances of bricks have been increased by overcompaction, granular reinforcement and lime treatment.For the tile re-use way, mixes with quarry fines and hemp have been studied. The behaviour of fresh material has been studied with VEBE consistometer. Flexural and compression strengths have been measured on hardened mixes. Lime and water-reducing agent have been necessary for a good mechanical behaviour.The two re-use ways have been validated by measuring mechanical and physical performances of products manufactured at industrial scale. The optimal mix for CEB includes almost 80% of quarry fines. The CEB is classed in BTC40 category according to experimental standard XP13-901 (brick with a low water absorption level and resistant to water spray). The optimal mix for tile includes 60% of quarry fines and satisfies mechanical requirements for gypsum blocks

Der volle Inhalt der QuelleEarthen buildings can provide an answer to face difficulties in modern constructions in both terms of sociology, economics as well as ecology. However, the difficulty to understand and to predict their behavior prevent the spreading of this technique in developed countries. This PhD is part of a research program called “Primaterre” and founded by the French National Agency for Research. It aims at providing the necessary scientific knowledge to overcome this lack and at helping the creation of appropriate standards. This work is more precisely focusing on the impact of water on the mechanical behavior of the fine proportion of the material, including sand, silt and clay, and on three different earths coming from existing rammed earth constructions. In order to be able to produce samples as identical and homogeneous as possible, a mold has first been designed, which enable to manufacture cylindrical samples with diameter of 3.5cm and height of 7cm. A triaxial cell was used and, the second step was to design different devices allowing the measurement of axial and radial deformations, the conditioning at constant temperature, and the command of a variable moist air flux at both sides of the sample. Different types of tests have thus been realized : triaxial tests at different relative humidity, as well as swelling tests. The mechanical parameters thus obtained have been analyzed in comparison with material characteristics measured in parallel. Finally, results of swelling tests have been analysed using numerical modelling, in order to assess more complex material characteristics. This thesis work ends with an additional study, aiming at evaluating the impact of scale change on the mechanical parameters previously measured. Tests have been conducted on sample approximatively twice larger, and thanks to a simpler experimental device using measurement through image correlation
