Does gravel make concrete stronger?
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 much sand and gravel to use. Adding aggregate to the mix reduces the amount of water. With less water, the concrete is stronger and less likely to shrink and crack.
Does adding more cement make concrete stronger?
