What happens if you use cement without sand?

If you don't have enough paste, the concrete will dry with a honeycombed surface and may be too porous. If you have too much paste, the concrete will be easy to spread but more likely to crack when it dries. The water to cement ratio is very important when mixing concrete.

What happens when you mix cement and water?

Portland cement's chemistry comes to life in the presence of water. Cement and water form a paste that coats each particle of stone and sand—the aggregates. Through a chemical reaction called hydration, the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete.

Is there an alternative to sand?

Ground granulated blast furnace slag (GGBFS or GGBS) is a by-product of iron and steel. It is obtained from quenching the molten iron slag from the blast furnace into water or stream. These glassy and granular products are then dried, and grounded into fine powder, which is also used as a substitute for sand.
