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. Advertisement Water also plays a ...

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 m 3 (30% more). The reason for that is the moisture content present in the sand makes it a little bulkier.
