摘要：

The worldwide productions of banana were bigger than 95 million tons, which resemble to, approximately, 10.22 million tons of ashes. Additions of these residues or banana leaf ash (BLA) in mortars were investigated by ratios of 0-10% in replacement to weight of the Portland cement as pozzolanic materials. The products were characterized by chemical compositions, SEM, rheology and pozzolanic activity index. Hardened materials were characterized by tearing it in walls. The mechanical and chemical resistance performances of 10% and 20% BLA concrete samples were also evaluated by artificial ageing chambers. The BLA was considered a pozzolan material.
