What happens if you don’t add sand to cement?
The proper ratio of materials will determine the strength of your concrete. Cement and water act as the paste of the concrete. If you don’t have enough paste, the concrete will dry with a honeycombed surface and may be too porous.
Can I make concrete with just sand and cement?
You cannot make concrete with only sand and cement because it requires a coarse aggregate like gravel. The stone component is the most critical, as that is what gives it its durability and strength. When mixing merely sand, cement, and water, you get a material closer to mortar.
What can I mix with cement to make it waterproof?

The amount of sugar that should be used to keep concrete from fully hardening ranges from 1.0 to 1.5 percent by weight of cement. It is important to note, however, that the effect of sugar is not to keep the concrete permanently plastic, but to keep its strength at a low enough level so that it can be easily broken up.
Can I mix PVA with cement?
PVA in Cement and Mortar PVA can be added to a cement mortar mix to give the mix a) slightly better waterproofing qualities and b) advanced adhesion to the surface it is applied to. Painting a coat of PVA on the surface before the cement mortar is applied can even further increase this adhesion.
