Potential of sugarcane bagasse ash as a partial replacement material for Portland cement
_ ABSTRACT
This study is focused on the evaluation of the effects of the partial replacement of Portland cement by sugarcane bagasse ash (CBC) in mortars. The main objective ,,as to find a suitable destination for an agricultural residue generated in an increasing amount in Brazil,as a result of the boom of the use of ethanol as an alternative fuel to gasoline. Also,the use of CBC as a mineral admixture in mortars and concretes contributes to a decrease in the environmental impact of these n1aterials related to cement production. Experin1ental techniques were applied both for the CBC characterization and for the evaluation of its use as a mineral admixture in mortars,based on mechanical and physical tests. The yield of CBC from sugarcane bagasse burning was 10°/o (weight basis) . The CBC presented a Si02 content of 84°/o and a carbon content
