The ideal cement and sand mix ratio for optimal strength in a concrete mixture is typically 1 part cement to 3 parts sand. This ratio helps ensure a strong and durable concrete mix.
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
The recommended mortar mix for concrete blocks is a 1:3 ratio of cement to sand.

There are different concrete mixes and the will depend on which mix it is. The material ratio will remain the same whatever the volume is.
The recommended mix ratio for Portland cement in concrete is 1 part cement, 2 parts sand, and 3 parts gravel or crushed stone. This ratio helps to achieve optimal strength and durability in the concrete.
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
The mix proportion for M40 concrete is 1:1.65:2.92W/C ratio = 0.4The design calculation is as per IS mix design
