The use of self-compacting concrete (SCC) has developed considerably in recent years, and much attention is paid to the study of their mechanical and rheological properties. The environment is a very important issue, and its preservation is a common responsibility, the wastes thrown by human beings compose a great danger on the environment, so it is necessary to encourage their elimination by recycling operation and their use as aggregates in the manufacture of self-compacting concrete. The study is based on the idea that the incorporation of rubber aggregates improves some behaviors of the SCC and enhances the use of waste, so the incorporation of aggregates in the composition of self-compacting concrete (SCC) has an interest that deserves to be studied. The objective of this work is to valorize the use of waste, especially used tires as rubber aggregates and also consists in studying the influence of the incorporation of these aggregates on the mechanical behavior of the self-compacting concrete. The dosages used in aggregates are of the order of 1 and 2% by weight of the concrete. This study will examine the role and influence of the rubber aggregate content on the characteristics of the SCC. The incorporation of these aggregates in the SCC is beneficial for the improvement of the ductility of the concrete material known for its brittleness in traction. The results of this work suggest that the pneumatic aggregates can be compared to other aggregates used as reinforcement in self-compacting concrete. They are completely suitable for use as reinforcement in self-compacting concrete.
