General Reduction

A lot of research has proposed the use of alternative materials in concrete, one of such material that has gained a lot of attention is the waste tire rubber. In this research, rubber crumb was used to partially replace fine aggregate in concrete at 0, 4, 8, 12, and 16% and represented as M0, M4, M8, M12, and M16, respectively. Sieve analysis was carried out on the rubber crumb and sand, while slump, compressive and tensile test were carried out on the concrete samples. The sieve analysis revealed that both the fine aggregate and rubber crumb are poorly graded. The slump test showed that the concrete losses it consistency as more rubber crumb was added. The 28 days compressive strength showed that there was a general reduction in strength. The work concluded that rubber crumb can be used to replace fine aggregate up to 16%, in lightweight concrete.

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.

Abstract This article aims to perform statistical analysis on the inclusion effects of waste tire rubber and fly ash from thermoelectric plants as mortar components for coating buildings. Reference mortars and mortars containing 5% and 10% rubber with a maximum grain size of 0.71 mm and mortars containing fly ash particles with a diameter of 45 μm were produced. Mortars containing rubber replaced 5% and 10% of the fine aggregate mass by this material and fly ash was added in 10% and 20% proportions compared to the cement volume. A 3² factorial experiment was performed on the mechanical properties of the compressive strength of mortars, applying analysis of variance (ANOVA) and surface response. The rubber waste material contributed to the decrease in compressive strength of the mortar and that factor displayed the highest significance in the response variable.

Abstract The recent increase in the construction industry has transformed concrete into an ideal choice to recycle a number of residues formerly discarded into the environment. Among various products, porcelain tile polishing, limestone and tire rubber residues are potential candidates to replace the fine aggregate of conventional mixtures. The aim of this study was to investigate the effect of the addition of varying contents of these residues in lightweight concrete where expanded clay replaced gravel. To that end, slump, compressive strength, density, void ratio, porosity and absorption tests were carried out. The densities of all concrete formulations studied were 10% lower to that of lightweight concrete (<1.850 kg/m³). Nevertheless, mixes containing 10 to 15% of combined residues reduced absorption, void ratio and porosity, at least 17% lower compared to conventional concrete. The strength of such formulations reached 27 MPa at 28 days with consistency of 9 to 12 cm, indicating adequate consistency and increased strength. In addition, the combination of low porosity, absorption and voids suggested improved durability.

Reusing rubber particles from used tires is good for the environment and, moreover, the world's population is becoming progressively conscious that a very high demand for natural resources is unsustainable. As the concrete industry consumes high amounts of natural resources, both for clinkering and gravel aggregate production, one must focus on its sustainability, considering environmental and economic issues. Therefore, reuse of waste tire rubber in concrete or in other composite materials is a logical solution for sustainable production of construction materials. Hence, the paper is aimed at the development and testing of lightweight concrete composed of a high volume of crushed waste tire rubber used as partial replacement of natural silica aggregate. In order to access the effect of incorporation waste tire rubber-based aggregate in concrete composition, reference concrete mix based on silica aggregate only is studied as well. The crushed waste tire rubber is characterized by its powder density, specific density, and particle size distribution. Specific attention is paid to thermal transport and storage properties of waste rubber that are examined in dependence on compaction time. For the developed lightweight concrete, mechanical, hygric, and thermal properties are tested. The tested lightweight concrete is found to be alternative and environmentally friendly construction material possessing improved thermal insulation function, interesting hygric parameters and sufficient mechanical resistance.
