    How Coarse Aggregate Affects Mix Design of Concrete?, Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix That is why it greatly affects the concrete mix design Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture It is reported [,]concrete RecycledAggregate [Read, recycled coarse aggregates and conventional fine aggregate can obtain an adequate compressive strength The use of recycled fine aggregate can result in minor compressive strength reductions However, drying shrinkage and creep of concrete made with recycled aggregates is up to higher than concrete with a corresponding conventional aggregate
