To achieve a true characteristic strength, assessment of the mix design must be carried out pre-contract. If a large quantity (several cubic metres or more) of concrete of specified characteristic strength is required, then it is suggested that ready-mixed concrete is used. For a smaller quantity, on-site batching (volumetric) suppliers can ...

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.

Grades of Concrete. Actually, what do we mean by grade of concrete.? Concrete grades are denoted by M10, M20, M30 according to their compressive strength. The "M" denotes Mix design of concrete followed by the compressive strength number in N/mm 2

Mixes are measured in grades, with strengths ranging from 10 Newtons through to high strength concrete mixes available online at 45 Newtons. A C20 mix has a relatively low cement content, meaning that the strength of the mix is one the lower mixes of the design concrete products that we offer.
