Civil - Civil-Jungles. This concrete mix ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture.. This concrete mixture ratio of 1 part cement, 1 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 2500 to 3000 psi.
A commonly used range for the water-to-cement ratio in concrete mixes is that for every unit of cement (by weight), there would be approximately 0.4 to 0.6 units of water. For example, if a concrete mix has a water-to-cement ratio of 0.4, it means that for every 100 pounds of cement used, there would be 40 pounds of water.
Timing. Ideally, when working with paving that has been laid on a cement-bound bed and or with buttering mortar, the pointing should be undertaken within 4 hours of the paving being laid, while the joints still have fairly fresh mortar within them from the buttering process. The pointing will 'top-up' the buttered mortar to form a solid mass with no day …
