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.

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.

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.

The use of waste materials as alternative aggregates in cementitious mixtures is one of the most investigated practices to enhance eco-sustainability in the civil and construction sectors. For specific applications, these secondary raw materials can ensure adequate technological performance, minimizing the exploitation of natural resources and encouraging the circular disposal of industrial or municipal waste. Aiming to design and develop lightweight paving blocks for pedestrian or very light-traffic purposes (parking area, garage, sidewalk, or sports surfaces), this paper presents the material characterization of rubberized cement mortars using ground waste tire rubber (0–1 mm rubber powder and 1–3 mm rubber granules) to totally replace the mineral aggregates. Considering recommended requirements for concrete paving members in terms of mechanical strength, water drainage performance, acoustic attenuation, and dynamic and energy absorption behavior, a comprehensive laboratory testing is proposed for five different formulations varying the sand-rubber replacement level and the proportion ratio between the two rubber fractions. Tests highlighted positive and promising results to convert laboratory samples into pre-cast members. The “hot” finding of the work was to prove the feasibility of obtaining totally rubberized mortars (0 v/v% of sand) with suitable engineering performance and enhanced eco-friendly features.

AbstractThe engagement of waste tires rubber as source of raw materials for different applications can be a partial solution to the great environmental problems caused by these products. In this study, waste tire rubber was devulcanized using both mechano–chemical and microwave methods. This process was achieved using different concentrations of 2-mercapto benzothiazole disulfide (MBTS) and tetramethylthiuram disulfide (TMTD) as a devulcanizing agent and different microwave devulcanizing times. The optimum content of both MBTS, TMTD and suitable microwave treatment time to make continuous film were noted. The devulcanized waste rubber was then added, at different concentrations, to virgin styrene–butadiene rubber (SBR). The thermal properties and dynamic mechanical behaviors were investigated for all blends. The thermal analysis proved that natural and styrene butadiene rubber are the main two constituents of the waste tire rubber utilized in this study. The mechanical behavior of the SBR blends remarkably improved by using 20 phr waste rubber (WR) devulcanized by 2 phr MBTS and by exposure for 2.2 min to microwaves. Storage modulus, tearing strength and tension set behaviors notably improved for all SBR/WR blends by irradiating with gamma ionizing radiation with a dose of 100 kGy and further improvement could be attained by increasing the dose up to 200 kGy.
