Does adding more cement make concrete stronger?
Answer (1 of 7): Sometimes and to a certain extent yes. But the additional cement must take the place of something and that something is intrinsically stronger than pure cement paste. Concrete strength comes from the homogenous blend of sand, cement, and stone. There are optimal ratios. In my yo

Properties of Good Sand
Followings are the desirable properties of sand: Should be completely inert. (i.e., should not have any chemical activity). Grains should be sharp, strong angular. Should not contain any hygroscopic salts (i.e., CaCl 2, MgCl 2, etc.). Should not contain clay silt; usually 3-4% clay silt is ordinarily permitted for practical reasons.

What Are the Strongest Types of Concrete?
Concrete Strength Concrete is a mixture of Portland cement, water and aggregate. The water/cement ratio is the determining factor of the strength of concrete. Concrete is stronger with less water in the mix. But water makes the concrete workable; the typical water/cement ratio balances strength and workability.

Sand Amount: A very high amount of sand will make your mix very brittle and weak against all kinds of forces. For M20, M25 etc, general proportion is 1:3. However, for High-strength mix (M35+) its better to go with 1:2 and somewhere about that. Aggregate Amount: Aggregates have two reasons to be there - economy and strength.

The lower the water to cement ratio, the stronger the mix will be, but as water is an essential element to the hydration process, it is necessary to ensure that enough is still used to saturate the mixture.

What water:cement:sand ratio gives the strongest mortar?
The correct mixing ratio would be 1:1.5:1 — 1 cement : 1.5 sand : 1 gravel stones with 0.4 water. If you use more water it will leave holes (porosity of the mortar), and if you use less water, it will not lead to hydration.
