This procedure is suitable for testing the compressive strength of concrete with strength grades C50~C100 in engineering structures. This procedure does not apply to the testing of concrete compressive strength under the following circumstances: 1. Concrete that suffers from severe frostbite, chemical erosion, and fire, resulting in inconsistent quality between the inside and outside, and concrete with uneven surfaces; 2. Concrete that is wet and formed by special processes; 3. Thickness Concrete components less than 150mm; 4 Concrete where the ambient temperature is lower than 0°C or higher than 40°C.
