How much Ballast do I need to Mix Concrete? All Mix Concrete
High strength concrete would be mixed using 1 part cement to 5 parts ballast this affords the sort of water-tight concrete used for building slabs or concrete panels. Mixing 1 part cement to 6 parts ballast creates concrete suitable for driveways, paths and patios, and increasing the ratio to 18 gives foundation-strength concrete.

Use of Water Reducers, Retarders, and Superplasticizer
By slowing the initial setting time, the concrete mixture can stay in its fresh mix state longer before it gets to its hardened form. Use of retarders is beneficial for The extended-set admixture is widely used as a stabilizing agent for wash water concrete and fresh concrete. The main disadvantage of superplasticizer usage is loss of

Grades of Concrete with Proportion (Mix Ratio) Civilology
Grades of Concrete. Concrete grades are denoted by M10, M20, M30 according to their compressive strength. "Mix" is the respective ingredient proportions which are Cement Sand Aggregate Or Cement Fine Aggregate Coarse Aggregate. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days.
