| Resume | The present study is integrated in general problems of development of building materials innovating with reduced environmental impact. Within this framework we proposed to study two types of cementing composite reinforced by vegetable biomass with knowing fibers of borassus aethiopum mart and the rice husk. To this end, studies of formulation, compatibility of cement with the biomass and of mechanical and thermal behavior of the batches formulated were carried out for two granular compositions of fineness 2.17 and 3. The study of compatibility revealed that the vegetable biomass well not having undergone a preliminary treatment in study are compatible with cement CPJ35.The comparison of the characteristics physical and mechanical of the two composites enabled us to conclude that the fibers concrete of borassus aethopium mart are better in term of mechanical performances. The values of the mechanical resistances corresponding to the optimum reports/ratios water/cement and cement/fibers are included respectively between 5.5 and 8.37 Mpa for the composite fibers of borassus aethopium mart.-cement and 3.63 and 12.25 Mpa for the composite rice husk-cement in traction and 6.84 and 16.26 Mpa for the composite fibers of borassus aethopium mart-cement and 3.8 and 15.63 Mpa for the composite rice husk -cement in compression. |
