Ecological cement: replacement of sugarcane bagasse ash derived from the sugar and alcohol industry
Cimento ecológico: substituição de cinzas de bagaço de cana-de-açúcar derivado da indústria sucroalcooleira

Biomass ash, Pozzolanic reaction, Supplementary cementitious material, Mineral replacement, Sustainable materialResumo
Untreated sugarcane bagasse ash (CBCA) from two plants was investigated as a partial replacement for Portland cement (CP) with the aim of reducing environmental problems arising from clinker production by evaluating the feasibility of use as a supplementary cementitious material with pozzolanic reactivity. Mortars and pastes were produced with replacement rates of 25%, 30% and 35% of CBCA, with cures of 7, 14, 28, 90 and 180 days. The mortars were characterized in a fresh state through workability testing and in a hardened state through mechanical performance through compression and flexural tensile tests, water absorption and void index. The chemical composition, mineralogical composition, thermal analysis and formation of hydrate phases were carried out on the pastes and both ash. The ash tests showed that the CBCA-CM presented an amorphous halo and that it consumed portlandite in the process of forming the paste hydrates at 28 and 90 days. Mechanical performance tests showed that the ash has lower resistance at short ages and surpassed the control sample at long ages.
