Cement Mortar Floor Tiles Mixed Waste Tire Rubber

Abstract

The objective of this research was to study the use of waste tire rubber powder instead of sand in the production of cement mortar floor tiles, measuring 30 × 30 × 5 centimeters, which uses a cement-sand ratio of 1: 2.75 by weight, and using finely ground waste tire rubber powder to replace sand at 0, 2.5, 5, 7.5 and 10% by volume, The water-cement ratio (W/C) was obtained from the mortar flow table test. Transverse bending resistance test in dry conditions at 7, 14 and 28 days, water absorption and abrasion resistance test at 28 days, compared with TIS 826-2531. The results of the experiment showed that as the amount of waste tire rubber powder replaced by sand increased. As a result, the value of water absorption, abrasion resistance and transverse bending resistance decreased. Waste tire rubber ratios instead of sand 0, 2.5, 5 and 7.5% by volume passed the threshold. TIS 826-2531, where the ratio of cement mortar floor tiles using waste tire rubber powder instead of sand was the most appropriate in this study, with a transverse bending resistance in dry conditions of 5.08 MPa, water absorption value of 2.23% and abrasion resistance of 0.086 g at 28 days.
