Incorporating rubber aggregates into concrete

The results presented compare the mechanical properties of a reference mortar with those of a mortar incorporating 30% rubber aggregates. The effects of reinforcing with metal fibers (40 kg/m ³ ) with or without rubber aggregates were also evaluated.

The cement used is CEM I 52.5R. As natural aggregates, we used rolled silica sand from Garonne. Rubber aggregates derived from the shredding of used tires are used as an absolute volume substitute for sand. Their...
