报告摘要：
This work enrolls in the context of eco materials. It concerns the field of transformation of   local shrub forest resources and lateritic earth with low market values into building materials and is developing a process for the valorization of lateritic nodules, Borassus aethiopum (palmyra) and Calamus deerratus (rattan) in the engineering of modern reinforced concrete structures. The objective of this process is to promote the rational use of these local materials in the realization of the floors of social housing. Experimental studies of physical and mechanical characterizations of the lateritic concrete formulated, of the palmyra and rattan woods were carried out. Through tests of tearing and sliding of the interface between normal concrete and laterite concrete (push-out tests), it has been highlighted the adhesion of palmyra wood to concrete and the contribution of rattan lianas to oppose the longitudinal sliding of the interface between two concretes of different nature. The case study of a hollow body slab in mixed concrete (normal and laterite concrete) reinforced with palmyra and rattan woods, showed the structural effectiveness of lateritic earth, of palmyra and rattan woods in the realization of social housing modern slads with a range of up to 5 meters.
