Concrete Mix Design Different Grades of Concrete

22/08/2017 To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-

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. This process is usually adopted for structures which requires higher grades of concrete such as M25 and above and

c) Other merits: Mix design can help us to achieve form finishes, high early strengths for early days, concrete with better flexural strengths, and concrete with lower densities. 1.3 Concrete design properties Concrete needs to be designed for certain properties in the plastic stage as well as in the hardened stage. Properties desired from concrete in plastic stage: • Workability

Conventional grade C20, C25 and C30 concrete mix ratio

The basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design. 2, meet the concrete peaceability. 3, meet the durability of the use of concrete. 4, meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades, such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60
