MAKING AND CHARACTERIZATION OF POLYMER CONCRETE WITH AGGREGATE FROM SAND, FLOAT STONE AND SUGAR CANE WASTE AS SOUND ABSORPTION

Environmentally friendly polymer concrete by utilizing waste has been widely developed, one of them is pumice and bagasse fiber waste. The use of these two wastes has not been optimal, for that by being used as fillers in concrete polymers are expected to have a higher economic value. This study aims to determine the optimal composition of natural binder and to know the mechanical characteristics and sound absorption of polymer concrete which is fabricated using pumice, sand and sugarcane waste with epoxy resin adhesive. The composition variations made are sand, pumice (1: 1) or (50 gr: 50 gr), rubber yarn solid waste 0%, 1%, 2%, 3%, 4% and 5% of the total weight of sand and stone buoyant, variations in the composition of polyurethane 20%, 25% and 30% of the total weight of sand and pumice. Then the characterization was carried out in the form of density test, porosity, compressive strength, flexural strength, polymer concrete morphology, and sound absorption coefficient. From the test results obtained the characteristics of polymer concrete have optimum value, namely density (1.655 gr / cm3), water absorption (8.864%) porosity (16.151%), compressive strength (8.59 MPa), flexural strength (18.171 MPa), impact strength ( 2,376 KJ / m2). Sound absorption coefficients were obtained for samples B6 (1.00), A6 (0.48) and C6 (0.20). This polymer concrete is lighter than conventional concrete that has better strength.
