Crumb rubber impact to the mechanical performance of concrete based at round gravel

Today the concrete is used more than any other construction material, with almost four (4) billion cubic meters used worldwide [1]. Throughout history, mankind has used concrete in construction. Concrete has not only been used in the construction of buildings such as dwelling areas but also in bridges, roads, tunnels, airports and water dams. It is a heterogeneous composite resulting from cement, aggregates, water and a limited quantity of adjuvant. The round gravel is an existing traditional material within the formulation of concrete. It is high in resistance to fragmentation and widely spread out in grand quantity in the Saharian regions. However, its utilization remains rare in different types of construction. The purpose of this study is to compare and contrast the use of local materials (Round gravel) with polymer industrial products (Crumb Rubber). This one is used to enhance the density, homogeneity, malleability and strength of the construction material.
