摘要: AbstractThe purpose of this study is firstly to investigate the effect various treatments on chemical and morphological properties fibers two xerophyte plants (Doum ‘Chamaerops humilis’ Diss ‘Ampelodesmos mauritanicus’), in order improve adhesion between cement matrix, secondly increasing inclusion rates these physical, mechanical thermal cementitious composites. Obtainable results by infrared spectroscopy, X-ray diffraction scanning electron microscopy revealed that alkaline Doum with 1 3% NaOH for 30 min at room temperature resulted an optimal improvement crystallinity index alter characteristics surface topography. The reinforcement mortars caused a decrease their bulk density consequently compressive strength, as well increase porosity thus capacity water absorption. Moreover, t...
