Different Types & Sizes of Aggregate for Concrete ...

Aug 11, 2018· Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate.
