Concrete Mix Design Calculation M20, M25, M30

Sep 06, 2016 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.

• Proper design and construction are absolutely necessary if the pavement is to perform. • Must be uniform throughout pavement’s life. • Poor subgrade/subbase preparation can not be overcome with thickness. • Any concrete pavement, built of any thickness, will have problems on a poorly designed and constructed subgrade or subbase.

An example of proportioning a mix design through use of this form is detailed in Table 3.1. The contractor establishes the initial parameters for a mix design and serves as the starting point for subsequent proportioning calculations. The initial step in proportioning the mix design is to calculate the water content per cubic yard of concrete.
