Use of Waste Tire Rubber Particles as a Part of an Aggregate Added to Thermal Insulting Mortar

Abstract:

Effect of waste tire rubber particles (WTRP) and glazed hollow beads as an aggregate on mechanical properties and thermal conductivity of thermal insulting mortar was studied. Several mortar mixtures were prepared by keeping the accumulated volume of both WTRP and glazed hollow beads equal to 1 m³ and by using WTRP contents of 0, 125, 250, 375 and 500 (its accumulated density) kg/m³ respectively. Results indicate that dry bulk densities of the mortars containing WTRP are all less than 900 kg/m³. The mortars or the WTRP have a certain hydrophobic property. The 28 d compressive strengths of the mortars are 1.4~2.0 MPa. And the thermal conductivity values are 0.095~0.139 W/(m.K) increased with the WTRP content increasing. The results suggest that the mortars containing WTRP as a part of an aggregate can be used as thermal insulating material.
