Mechanical and restrained shrinkage behaviors of cement mortar incorporating waste tire rubber particles and expansive agent

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.

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 present study is performed for investigation of the correlation between UPV value and strength of rubber-concrete. Compressive and splitting tensile strengths of concrete containing waste tire-rubber particles by four different volume contents were investigated using ultrasonic pulse velocity (UPV) test and direct destructive tests. Test results showed that ultrasonic pulse velocity test can be successfully estimated to the strength of rubber-concrete as used in normal concrete.

Waste Tire Rubber

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.
