1.0.1 This standard is established to unify the method for evaluation of concrete compressive strength, promote enterprise to improve its management level and ensure the quality of concrete compressive strength.
1.0.2 This standard is applicable to evaluation of compressive strength of ordinary concrete and light-weight aggregate concrete.
As for concrete with special requirements, the evaluation for its strength shall also meet the relevant requirements of the current national standard.
1.0.3 In addition to the requirements of this standard, the evaluation of concrete compressive strength shall also comply with the relevant requirements of the current national standard.
Note: as for the engineering designed according to TJ 10-74 Code for Design of Rebar Concrete Structure, when using this standard to carry out evaluation of concrete compressive strength, it's required to convert concrete mark adopted in design into concrete strength grade according to the requirements of Annex 1 in this standard. The concrete mixing strength during construction shall also be converted according to the same principle.
