1. Introduction. Concrete is the most widely produced material for construction and the second most consumed material in the world. It is estimated that each human being uses three tons of concrete per year (Gagg, 2014).Concrete is a composite material consisting primarily of cement and coarse and fine aggregates.

However, using a recycled aggregate of more than 65% can impact the mix's durability significantly, reducing its physical properties tenfold. The optimum amount blended in with the concrete should be 35%. Some experiments have shown that the recycled aggregate is durable, no doubt, but not as sturdy as natural coarse aggregate.
