“…Approximately 275 million rubber tires are disposed of annually in the United Sates [22] and about 180 million in the European Union [23]. The heavy metals and other pollutants in tires create an environmental risk when the tires are placed in wet soils in the landfill, resulting in the leaching of toxins into the groundwater.…”

“…The major cause for the drop in the strength is the softness of the rubber particles are much softer due to this while compressive load applied to the specimen the crack propagation was very fast around the rubber particles which will affect the rubber-cement matrix and leads to the failure [12][13]. Two point load was applied to the specimens and the breaking load for the specimens were measured.…”

Abstract. In this paper, the experimental investigations was carried out to find the compressive strength, static modulus of elasticity and flexural strength of concrete mixtures, in which natural sand was partially replaced with Waste Tyre Crumb Rubber (WTCR). River sand was replaced with five different percentages (5%, 10%, 15%, 20% and 25%) of WTCR by volume. The main objective of the experimental investigation is to find the relationship between static modulus of elasticity and flexural strength with compressive strength of concrete with WTCR. The experimentally obtainedstatic modulus of elasticity and flexural strength results comparing with the theoretical values (various country codes recommendations).

“…Rubber is the principal element of tyres where both synthetic and natural rubbers may be used. Rubber consists of many polymeric repeated units (mainly polybutadiene) chained together [24]. Natural rubber is an elastic variety of plants.…”

Abstract. Nowadays, uncontrolled disposal of waste materials such as tyres can affect the environment. Therefore, careful management of waste disposal must be done in order to conserve the environment. Waste tyres can be use as a replacement for both fine aggregate and coarse aggregate in the production of concrete. This research was conducted to assess the durability of concrete containing recycled tyres which have been crushed into fine fragments to replace fine aggregate in the concrete mix. This study presents an overview of the use of waste rubber as a partial replacement of natural fine aggregate in a concrete mix. 36 concrete cubes measuring 100mm x 100mm x 100mm and 12 concrete cubes measuring 150mm x 150mm x 150mm were prepared and added with different percentages of rubber from recycled tyres (0%, 3%, 5% and 7%) as fine aggregate replacement. The results obtained show that the replacement of fine aggregate with 7% of rubber recorded a compressive strength of 43.7MPa while the addition of 3% of rubber in the concrete sample recorded a high compressive strength of 50.8MPa. This shows that there is a decrease in the strength and workability of concrete as the amount of rubber used a replacement for fine aggregate in concrete increases. On the other hand, the water absorption test indicated that concrete which contains rubber has better water absorption ability. In this study, 3% of rubber was found to be the optimal percentage as a partial replacement for fine aggregate in the production of concrete.
