The Mix Design process is normally implemented for the structure that needs higher grades of concrete like M25, M30, etc, and where consumption of Concrete is high. Concrete Mix Design for M20, M25, M30, and higher grades of concrete can be calculated from the example given below.
Quantities derived through the nominal mix method and design mix method are different from each other. From experimentation, we find out that M15 grade concrete, batched through the nominal mix method, has equivalent quantities of materials as M20 grade concrete batched by the design mix method. WHAT IS M15 GRADE CONCRETE?

02-05-2020· Different grades of concrete have different proportions. Same, Different grades of Concrete Mix design need a different quantity of water. Don't forget, excessive use of water in concrete may lead to shrinkage and creep. M20 Grade of Concrete requires approximate 200liters or 53 gallons of water.
06-09-2016· 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.
