Jul 31, 2019 The C20 concrete mix is a medium-strength concrete recommended for basic household constructions such as retention of posts, garden walkways and many more. This cement and sand mix is, however, not recommended for use in constructing a foundation and other construction works that would need super resilient concrete.
Concrete strength is measured by the weight it can withstand 28 days after it has been laid and cured. Our concrete strengths range from grade C10 to C40. C10, with a strength of 8 newtons, is designed for kerb backing and bedding. C40, our strongest concrete with a strength of 40 newtons, is designed to withstand heavy-duty loads.
Concrete mixed at this ratio is generally known as a C20 mix and its more than suitable for garden paths, concreting fence posts, shallow retaining wall foundations, some extension bases, shed bases and many other domestic and commercial applications. C20 is a medium strength concrete mix.
