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 aggregate...

This study investigates the effect of aggregate size on the compressive strength of concrete Two nominal mixes that is 124 and 136 were used in the study
More Details
Also the results show that the compressive strength increases with increasing aggregate size up to 125 mm while the concrete produced using 20 mm had greater compressive strength than those produced using 25 mm aggregate This established the importance of ensuring that the right aggregate size is used in the production of concrete
