2021-6-2 The Impact of Crushed Sand on Dry Concrete. In the hardened state, there are a few more points to note. Mix designs with artificial sand can suffer from having a higher demand for water per cubic meter of concrete.

Environmental considerations cause pressure on concrete producers to reduce their use of natural sand. The availability of sand is also reducing and in many countries, authorities have put restrictions on the use of natural sand. Crushed rock and waste aggregate tend to have less rounded edges and corners resulting in poorer flow of fresh mortar.
