Mechanical characterisation of filler sandcretes with rice husk ash additions

摘要: Abstract To capitalise on the local materials of Senegal (agricultural and industrial wastes, residual fines from crushing process, sands dunes, etc.), rise husk ash residues agricultural wastes have been used as additions in sandcretes. The mechanical resistance sandcrete blocks obtained when unground (and notably ground ash) is added reveals that there an increase performance over classic mortar blocks. In addition, use rice enables production a lightweight with insulating properties, at reduced cost .The pozzolanic reactivity explains high strengths obtained.
