Effect of Aggregate Size on Strength

How much stronger is a floor made with 1/2-inch aggregate than one with 3/4-inch aggregate if all other ingredients remain the same? A.: If the quantities of coarse aggregate, fine aggregate, cement and water are the same for both mixes, the mix with l l/2-inch aggregate will have greater slump and will probably bleed more.

Does Aggregate Size Affect Concrete Shrinkage?

To produce a workable concrete, a small maximum-size aggregate such as pea gravel requires a higher sand content than does a larger maximum-size aggregate. This increases the aggregate surface area that has to be coated by cement paste. If you left the cement paste content the same, each aggregate particle would have a thinner …
