One of the most common lightweight mixes we deal with is GEN 3 / C20 concrete. With a strength rating of 20 newtons after 28 days, this mix is commonly used for domestic projects, but can also be used for certain commercial applications. As a lightweight mix, GEN 3 / C20 concrete has the highest cement content of all other individual GEN mixes.

But the British standard mainly uses the cube strength as characteristic strength to represent the concrete in the design formulas. Therefore, knowing the relevant strength classes or the relationship between the structure are important. As it appears, there is no linear relationship between the cube strenth and the cylinder strength.
