ANALYSIS OF THE PROPERTIES OF CONCRETE BLOCKS FOR INTERLOCKING PAVEMENT PRODUCED WITH ASHES FROM SUGAR CANE BAGASSE

Abstract

The objective of this work was to study the partial substitution of the natural (sand) aggregate by ash from sugarcane bagasse (CBC), by mass, in the proportions of 10% and 20% for the preparation of pieces of concrete for interlocking pavement. Firstly, the pilot trait was developed, this one still without the addition of CBC, which served as parameter for comparisons. The properties of the aggregates and the concrete were analyzed through standardized tests of granulometry, specific mass, slump test, compressive strength and water absorption. As for the values of compressive strength, the 10% substitution trait presented the best result of compressive strength, being 15% superior to the pilot trace. As for absorption, an increase in permeability was observed as the addition of CBC increased. Finally, it was concluded that the satisfactory trait in relation to the properties analyzed was the 10% substitution trait.
