Assessment of Ashes from Sugar Cane Bagasse in the Manufacture of Concrete Pavers

Abstract

The recycle of agroindustrial residues is one of the best solutions for two currently important issues: the scarcity of natural resources and the inadequate disposal of wastes. Current research studies the potentiality of the use of ashes from sugar cane bagasse to replace small aggregates in the manufacture of concrete pavers enduring light weight. Methodology comprises the characterization of residues, manufacture of pavers with different types of replacement of small aggregates and the determination of the pavers´ main features. Ash from sugar cane bagasse is a viable residue for the manufacture of pavers due to an expressive improvement of the characteristics analyzed (resistance to compression, absorption and abrasion) with regard to pavers made with the partial substitution of sand grain by ash bagasse.
