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 m3and by using WTRP contents of 0, 125, 250, 375 and 500 (its accumulated density) kg/m3respectively. 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.

The physical properties and mechanical behavior of cement mortars containing waste tire rubber particles (WTRP) were studied. Several mortar mixtures were prepared by replacing quartz sand with 100% of WTRP and by using cement content of 150, 200, 250, 300, 350 and 400 kg/m3 respectively. Results indicated that dry bulk densities of the mortars containing WTRP were all less than 1000 kg/m3. The mortars had a certain hydrophobic property. The 28 d compressive strengths of the mortars were 0.59~2.29 MPa and the thermal conductivity values were 0.096~0.152 W/(m.K) increased with the cement content increasing. So, the mortars containing WTRP can be used as thermal insulating material.

With the increasing number of vehicle due to the boom of population and rapid modernisation, the management of waste tire is growing problem. Reusing grinded tire rubber in concrete is a green innovation which provide an outlet for reusing waste tire. While providing certain benefits to concrete, incorporation of tire rubber results in significant loss of concrete compressive strength which hinders the potential of rubberised concrete. This paper aims to develop mathematical models on the influence of tire rubber replacement on the compressive strength of concrete using design of experiment (DoE). 33 data sets are gathered from available literature on concrete with waste tire rubber as partial replacement of fine aggregate. Response surface methodology (RSM) model of rubberised concrete compressive strength shows great accuracy with coefficient of determination (R2) of 0.9923 and root-mean-square error (RMSE) of 2.368. Regression analysis on the strength index of rubberised concrete shows that rubberised concrete strength loss can be expressed in an exponential function of percentage of replacement. The strength loss is attributed to morphology of rubber particles and the weak bonds between rubber particles and cement paste. Hence, tire rubber replacement should be done sparingly with proper treatment and control to minimise concrete strength loss.

AbstractWaste tire rubber is commonly recycled by blending with other polymers. However, the mechanical properties of these blends were poor due to lack of adhesion between the matrix and the waste tire rubber. In this research, the use of electron beam irradiation and (3-Aminopropyl)triethoxy silane (APTES) on enhancing the performance of 50 wt% reclaimed tire rubber (RTR) blend with 50 wt% poly(ethylene-co-vinyl acetate) (EVA) was investigated. Preparation of RTR/EVA blends were carried out in the internal mixer. The blends were then exposed to electron beam (EB) irradiation at doses ranging from 50 to 200 kGy. APTES loading was varied between 1 to 10 wt%. The processing, morphological, mechanical, and calorimetric properties of the blends were investigated. The stabilization torque and total mixing energy was higher in compatibilized blends. Mechanical properties of RTR/EVA blends were improved due to efficiency of APTES in further reclaiming the RTR and compatibilizing the blends. APTES improved the dispersion of embedded smaller RTR particles in EVA matrix and crosslinking efficiency of the blends. Calorimetric studies showed increased crystallinity in compatibilized blends which corresponds to improved mechanical properties. However, the ductility of the blend was decreased due to increased interaction between EVA and APTES. Presence of APTES increased the efficiency of electron beam irradiation induced crosslinking which was shown through gel content analysis and Charlesby-Pinner equation.
