Can you use cement on its own?
Cement is used by itself in fairly narrow applications, primarily as a grout when mixed with water. It can also be used to repair cracks in concrete.
What happens if you use cement without sand?
In order to produce a strong, resilient concrete mix, you need to get the ratio of aggregate to sand to cement right. So if you don’t mix sand to the cement, cement will set of course but will give a lot of shrinkage crack and may not give the desired bonding.
Is masonry cement the same as mortar?
