Importance of Gravel and Sand for Concrete Hunker

12.04.2018· Sand and gravel in concrete serve several purposes. Because they act as a filler, they also add more volume to the concrete. More volume means less air and a stronger product. The size of the gravel also helps to determine the concrete's strength. Though larger pieces of gravel produce more friction and make it harder to mix, they also make a stronger concrete. Water also plays a part in how

Effect of Fineness of Sand on the Cost and Properties of

The net cost of Concrete reduces when FM of sand increases. It reduces by about 6.5% for an increase of FM from 2.0 to 3.0. As the fineness modulus of Sand increases, the Cost/Benefit Ratio reduce by a very large factor. This is 29% when FM changes from 2.0 to 3.0. That means we can get large advantage by using concrete having Coarse Sand.

Bulking of Sand If the moisture is present in the sand, then it makes the sand look bulkier, which could result in inadequate sand proportion in the concrete ratio. If we need to add 1m 3 sand in the concrete mix ratio, we take 1.3 m 3 (30% more). The reason for that is the moisture content present in the sand makes it a little bulkier.
