Full textThe mechanical properties of concrete evolve in the course of time. This is the consequence of the chemical reactions which proceed during the hydration of the binder. As this one is overall exothermic, the follow-up of the quantity of released heat makes it possible to account for the kinetics of reaction. The devices adapted to concrete being very few, we developed our own isothermal calorimeter accepting 11x22 cm standardized cylindrical samples. After the calibration and the validation of the device, we passed to the second phase of our work which consisted in studying the reaction kinetics and parameters influencing the hydration. We thus studied five compositions of concretes and three compositions of Equivalent Concrete Mortars. The last phase of our work relates to the introduction of calorimetric measurements into maturity measurement studies. Indeed, the economic stakes related to the in situ forecast of young concrete strength are important. The maturity measurement is one of the techniques allowing to estimate this size. It is based on the concepts of "maturity" and "equivalent age", and on the Arrhenius' law which introduces the apparent activation energy parameter. It can be determined by the method of "superposition" from the curves of compressive strength obtained for various temperatures. However, this mode of determination is tiresome. For compositions of concrete and MBE, representative of those concerned with maturity measurement studies, we have compared the calorimetric and mechanical approaches of determination of Ea, and have shown that the calorimetric way can advantageously replace the mechanical way for the determination of this parameter

Full textThis study concerns building materials engineering and Cameroon's natural resources. The use of pozzolans allows to elaborate light concretes both thermal insulating and strong. The study of this new material, about a few point of view (chemical, mineralogical, physical, reactivity with lime, potential reactivity with alkalis) shows that, depending) on whether the deposits, some aggregates are better to be used as an admixture for cement after a mechanical treatment and another ones as ordinary aggregates in elaboration of concrete. The aggregates of natural pozzolans are porous, so the classical theory of concrete composition can't be used. A method based on vacuum factor with a triangular diagram of mixture fillers, sand, aggregates, allows to optimize the formulation in getting building material according to the three set tests, lightness, mechanical strength and thermal insulation

Full textA two-phase research program has been undertaken. In the first phase, computer simulations using a finite-element analysis (FEM) software have been performed to highlight the most sensitive. In the second phase, a series of 12 real-size reinforced concrete beams (3,4 m long) has been cast, air-conditioned and repaired at midspan to different extents, using two formulations of repair self-compacting concrete (high-stiffness and low-stiffness SCC’s), 10 of the 12 beams are repaired beam. The last 2 beams are monolithic beams and used as references. After the installation of the instrumentation, the beams are tested on a 4-point bending setup using two servo-hydraulic actuators, for the measurement of the instantaneous and long-term load deformation. The analysis that follows illustrates the correlation between laboratory results and numerical simulations. The main findings of the study show that using a repair material with a higher stiffness than that of the substrate results in a behavior similar to the monolithic beam. However the use of a material with a lower stiffness tends to negatively affect the behavior of the repaired beam. This trend is more pronounced when considering a sustained load, because the materials with lower stiffness tend to deform more than the rigid materials, it follows that the creep at the young age of the material also affects the behavior of the repaired beams, and that the use of a more rigid material allows the repaired beam to behave like a monolithic beam. Keywords: Beam, concrete, compression, creep, FEM, mechanical repair, structural capacity
