1. Strength—The influence of aggregate gradation on the compressive strength of finished concrete block will determine the necessary cement content to produce block which meet specified strength requirements. Since cement is the most costly ingredient in the concrete mix, the selection of a properly graded aggregate assumes an economic aspect. 2.

From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking. In this study, we have used grit and crushed sand for the design mix and found the characteristic compressive strength at 3,7 and 28 days respectively.

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 one-to-one 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.
