Standardized Prescribed Concrete (SPC)| BS 8500-2

SPC or standard mixes of concrete are concrete that are defined list of concrete within BS 8500, that mentions the prescribed quantity of materials as per the British Standard.

SPC is usually mixed at the .site or obtained from a supplier with no quality standards.

The strength guaranteed by these mixes is, fair as they are the basic concrete mixes, as they are designed based on the assumed values contained within BS 8500. The types of SPC, their strength  , and their applications are mentioned in table below.
