Properties of recycled aggregate and recycled aggregate Effect of Recycled Coarse Aggregate on Concrete Properties

In the present investigation an attempt was made to study the influence of the strength of parent concrete on the properties of recycled aggregates and recycled aggregate concreteRecycled aggregate can absorb more water than natural aggregate because recycled aggregate has many pores to absorb the water and it will influence the characteristic Strength Modulus Elasticity Based on the research result it can be seen that the increase of Recycled Aggregate will decrease the value of modulus elasticity
