Abstract
This work mainly relates to promoting the use of concrete based on sand and the incorporation of rubber aggregates (0-1mm) from recycling of used tires in volume substitution of sand with rates of 10, 20 and 30% in order to obtain materials with low environmental impact. In order to meet this objective, an experimental approach was carried out, which consisted in incorporating different percentages of rubber aggregates in the formulation of sand concrete. These concretes are characterized in the fresh and hardened state in order to study the effect of adding these rubber aggregates on the properties of self-compacting sand concrete. The results found show that the fluidity of the SCSC (expressed by spreading with the Abrams cone and the flow at the V-Funnel) improves with the increase in the dosage of rubber aggregates and these values are located within the recommendations of the French Association of Civil Engineering. They also show that rubber particles can improve certain desired technical characteristics such as ductility.
