The use of tire rubber in the production of high-performance concrete

Abstract

The advances in concrete technology lead to the search for alternative materials that provide improvements in concrete properties while at the same time collaborating with sustainable practices in construction. In this study, the influence of the incorporation of waste tire rubber on the mechanical properties of high-performance concrete was discussed. The waste rubber from the tire retreading process was used in partial substitution of the fine aggregate (sand) in the percentages of 7.5%, 15% and 30% with respect to the mass of the sand. For the characterization of the concrete, the following tests were carried out: water absorption, void index, specific density, compressive strength, flexural tensile strength, modulus of elasticity and microscopy analysis. The incorporation of rubber as aggregate in high-performance concrete proved to be promising for the production of a structural concrete with special characteristics, besides collaborating with the proper disposal of waste tires.

Influence of the Incorporation of Rubber Fibers on The Properties of Concrete Reinforced with Steel Fibers

“…The steel fiber also caused a small reduction, around 5% to 9% in both mixtures with the material compared to similar mixtures without steel fibers. This trend was also observed by Silva et al 7 , who used rubber tires to produce high-performance concrete, and by Gomes et al 12 who used recycled rubber aggregate for selfcompacting concrete and reported a 3.9% reduction with a 1% increase in rubber.…”

“…The use of waste rubber in the composition of composites as an aggregate recycled has been studied by several researchers 7,8 . Rubber when used in the composition of concrete and mortar decreases its specific mass and mechanical resistance 9,10 .…”

Mathematical modelling of concrete compressive strength with waste tire rubber as fine aggregate

“…In this study, waste tire rubber in fine size such as 0.30mm and 0.50mm [26] is used in a literature. Other studies use tire rubber with particle size similar to sand, which ranges from maximum nominal size of 1.00mm [27], 2.40mm [15], 4.00mm [13] and 4.80mm [14]. The physical properties of tire rubber are investigated in the literature and compiled in Table 1.…”

“…Despite its wide array of potential applications, one major challenge of waste tire rubber in concrete is the massive loss of strength incurred when tire rubber is used as partial replacement for fine aggregate. For example, Silva et al [14] prepared a high strength concrete with silica fume which achieved a compressive strength of 97.4MPa at 28 days but a strength drop of more than 20% is observed when 7.5% of the fine aggregate is replaced by tire rubber. At 30% replacement, concrete losses over half of its compressive strength as compared to control.…”

Uso Del Caucho De Neumáticos Triturados Y Aplicados Al Concreto: Una Revisión Literaria

“…Los resultados ilustraron que la resistencia a la compresión se redujo de 51% a 15% reemplazando todos los tamaños de partículas. (Silva et al, 2019), investigaron la influencia de la incorporación del caucho proveniente de neumáticos desechados en las propiedades mecánicas del concreto de alto rendimiento. El caucho residual del proceso de recauchutado de neumáticos se utilizó en sustitución parcial del agregado fino en los porcentajes de 7,5%, 15% y 30% con respecto a la masa de la arena.…”
