• ### Concrete Mix Design Calculation For M20, M25, M30 Concrete

what is standard mix this is an old technique for mixing concrete in a manner like 1 cement: 2 sand : 3 aggregates by their volume. mix the dry ingredients ( cement, sand, and aggregates ) and slowly add water until concrete becomes workable. this concrete mixture may need to be changed based on the aggregate used to provide workable concrete.

• ### Concrete Mix Design Calculation - M20, M25, M30

concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures. so, concrete mix design can be stated as concrete mix = cement:sand:aggregates. the concrete mix design involves various steps, calculations and laboratory testing to find right mix proportions.
