Waste tires and the burning of sugarcane bagasse in the manufacture of concrete pavers (pavers)

The research developed has the purpose of analyzing the potential utilization of sugarcane bagasse ash and tire residue in the construction of pavers in replacement of the small aggregate, the natural sand. In order to achieve this objective, the methodology adopted includes steps such as: characterization of the residues to be used, preparation of pavers with different contents of partial replacement of small aggregates, determination of the main pavers characteristics (compressive strength, water absorption, abrasion resistance) . The results proved the viability of the substitution, and the optimum content for the manufacturing of the parts is 27%, being 25% of BCC and 2% of tires. The contribution of the research is focused on reducing the consumption of natural resources and the correct disposal of the residues studied.

Keywords:
sugarcane bagasse ash; tires; pavers; recycling; durability.
