# grade 20 concrete mix ratio

A properly designed mixture possesses the desired workability for the fresh concrete and the required durability and strength for the hardened concrete. For example, if the concrete is M20 grade, it means the concrete will attain the characteristic compressive strength of 20 Newton per millimeter square in 28 days after curing. The grade of concrete is also denoted as C16/20, C20/25, C25/30, etc., which means Concrete Strength Class (C) the number behind C refers to Compressive strength of Concrete in N/mm 2 … Concrete Mix Ratio. We have given the materials requirement for M15, M20, M25 and M30 Grade Concretes in the blog. Concrete strength classes 20/25 and class 25/30 can be produced with Portland-limestone cement grade 42.5 using 1:2:4 and 1:1.5:3 mix ratios respectively. C20 is 1:2:4(1 part cement, 2 parts fine aggregate, and 4 parts coarse aggregate.) 20 MPa is expression or Unit to show Compressive Strength of CMR (Concrete Mix Ratio). Reply Link.

The mix ratio of 1:2:3 consists of 1 Part cement, 2 Parts sand, and 3 Parts stone (plus some water) to make a concrete mix you can use for most any building project. As we know that during concreting when we place wet concrete its gets hardened after certain standard time 30 minute to 10 hours and voids of concrete is completely evaporated so there is decrease in their volume and there volume is decrease by about 54% it means dry volume of concrete is increased by 54%, We have given Volume of wet concrete = 1m3, And we know that dry volume of concrete is 1.54 times of wet concrete volume. Concrete grades are denoted by M10, M20, M30 according to their compressive strength. Simple grade of concrete is m5, m 7.5,m10,m15, m 20 having decided grade of concrete mix ratio according to their nominal mix. A concrete of Grade C20 means that the concrete will have a compression resistance of 20 N/mm2 per square millimeter in 28 days. This paste is also called as concrete. between Water and Cement of the fresh mix concrete. In BS 8110: Part 1: 1985, the improved durability of concrete is achieved by using mixes with higher strength such as Grades 25 and 30. This will be based on some parameters they will have to explore.
