Is compressive strength test required for standard mixes of concrete?

Is compressive strength test required for standard mixes of concrete?

In some countries like Britain, specification for concrete does not normally require cube tests for standard mixes of concrete. The quality control of standard mixes in Britain is achieved by checking if the appropriate mix proportions are adopted during the mixing of concrete. However, in Hong Kong the requirement of testing for compressive strength is still required for standard mixes in the specification because it is impractical to inspect and check all constituent materials (e.g. cement, aggregates etc.) for concrete for compliance.

As there is high variability in mixing materials owing to variance in the origin of production of constituent materials in Hong Kong, there is a risk that the end-product concrete does not comply with the design requirements even though the mix proportions of standard mixes are followed closely by engineers.


This question is taken from book named – A Self Learning Manual – Mastering Different Fields of Civil Engineering Works (VC-Q-A-Method) by Vincent T. H. CHU.

hi…can u pls give info about the appropriate mix proportion for different grades of concrete???

dean says:

in our country, climate is rainy but at interval sessions. so sometimes, the truck are dispatched from rainy areas but intended destination is sunny. as such , compressive 28days is implemented
