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 475mm sieve the aggregate retained is called coarse aggregateFurther Details
Depending on the mix design either can be used to make essentially any range of concrete strengths When you use a smaller aggregate such as the 10mm as your nominal coarse aggregate size the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregateFurther Details
