Can I Make Concrete with Just Sand and Cement? (What To Do)

Aug 13, 2020· Image by jarmoluk via Pixabay. Just as you can make no-fines concrete without sand, you can create a concrete mix that incorporates a high proportion of sand. However, concrete that incorporates higher levels of sand compared to coarser aggregates will be weaker overall and cannot be used for structural applications or where support or load-bearing abilities are required.

Replacing natural sand by crushed rock in concrete using

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.
