Using Recycled Concrete AggregateSpecify Concrete

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.
