ANÁLISE DAS PROPRIEDADES DO CONCRETO ESTRUTURAL UTILIZANDO A CINZA PESADA DO BAGAÇO DA CANA-DE AÇÚCAR.

Nowadays Brazil the leading producer of ethanol and sugar in the world, and is therefore the largest producer of sugarcane. Thereby, for such large production, large volumes of waste are created and we seek to use them to reduce the volume of waste in the environment. Bagasse is the residue from the production of ethanol and sugar, and it is used for the cogeneration of electric energy which results in a final residue: the ashes. Those ashes are discarded in landfills occupying a large volume and generating a larger environmental impact. This work has the objective of making concrete with partial substitution of small aggregate by the heavy ash of the sugarcane bagasse, with different levels of substitution (0%, 10%, 20%, 30% and 40%), by mass. The concretes were characterized in the fresh condition for consistency, and in the hardened condition for the compressive strength and water absorption. The results confirm that the replacement of sand by heavy sugarcane bagasse ash (BCC) was satisfactory, since the greater the amount of BCC plus resistance of rupture. [ABSTRACT FROM AUTHOR]
