Abstract
Concrete is one of the most used construction materials in the world, with cement being one of its main ingredients. The incorporation of Sugarcane Bagasse Ash (SBC) in the production of concrete can present solutions for the use of this agro-industrial by-product and minimize environmental impacts arising from the removal of limestone in the production of cement, in addition to contributing to the reduction of emission of carbon dioxide and preserve natural deposits for cement production. This study aimed to use sugarcane bagasse ash in the addition and partial replacement of cement in the production of concrete. The specimens (TBs) were manufactured following the NBRs 7223 and 5738, in which a ratio was adopted: (1:1.98:3.23:0.61) as primary proposal (T1), and the replacement (T2) and addition (T3) of 5% of Portland cement by mass was performed. The ruptures of the specimens were performed by the compressive strength test of concrete cylindrical specimens at 7, 14, 21 and 28 days of age, after rectification. The results obtained show that it is feasible to use SBA, since the water/cement ratio and the percentage of mass to be replaced or added are appropriate, because both in the addition and the replacement of 5% cement by SBA obtained a gain in strength of concrete.
