摘要: AbstractThis paper studies the effect of rice husk ash (RHA) in properties hydrated lime (calcium lime-CL90s) mortars with a view to improve their and make them more sustainable. The variation mortar was related activity RHA, which assessed by measuring its specific surface area, fineness, reactivity, composition, amorphousness. According results, RHA investigated is low-temperature, highly reactive high area that contains crystalline silica unburnt cellulosic material probably produced between 400 500°C. Pozzolanic hydrates were clearly present after 24 h, progressively increasing size amount (at 3 7 days) linking each other form continuous networks 14 days. concludes replacement improves workability, lowering water/binder ratio water required reach consistency. also enhances bulk density lowers ...
