    These restrictions limit maximum aggregate size to 1 1 2 inches, except in mass applications. Higher maximum aggregate size lowers paste requirements, increases strength and reduces w c ratios. However, excessively large aggregate tends to lower strength by reducing available bonding area. ASTM has limits for grading of concrete aggregates.The type of coarse aggregate has no influence on the air content in concrete. Concrete compressive strength mainly depends on the quality of recycled aggregate.
