The impacts caused by RCCs are growing exponentially each year,which is why it is necessary to create measures to mitigate and minimize suchan effect. The purpose of this research was to evaluate the physicalmechanical properties of the concrete from the gradual replacement of thenatural fine aggregate by the recycled aggregate. The recycled concrete wasmade with substitutions of 20, 40, 60, 80 and 100% of recycled aggregate,whose water / cement factor was 0.7. Test specimens were produced and afterthe cure time of 7, 14 and 28 days the specimens were ruptured. It waspossible to analyze that with the increase of the recycled aggregatesubstitution, the concrete strength increased, but did not reach an averageresistance of 20 Mpa. Therefore it is possible to conclude that the use ofrecycled aggregate in the manufacture of low resistance concrete is.
