Concrete Mix Design Calculation M20, M25, M30 Procedure
Concrete Mix Design Calculation for M20, M25, M30 Concrete with Procedure & Example. 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.a day is illustrated in the Figure 4. The strength of the concretes with intermittent curing one times varies a day with respect to the number of days increased. The maximum strength developed by the concrete mix-M20 on 28 days curing one times a day is 20.93 MPa, whereas after 15 days same concrete mix gains 17.58 MPa.
