How Does the Ratio of Sand to Cement Affect the Strength ...
Increasing the Strength. Adjusting the strength of concrete based on the ratio of sand to cement is easy to do. The closer you bring the ratio to an even onetoone ratio of sand to cement, the stronger you will make the concrete. On the other hand, if you push the ratio in the other direction you will get a product that has slightly less strength.
