3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 compressive strength Rd The maximum compressive stress that a specimen can withstand under axial compression until failure. Note. The unit is MPa. 3.2 ε0 The axial strain is calculated by dividing the axial change in the original length by the original length when the specimen is subjected to axial compression until failure. Note. Expressed in percentage (%). 4 Principles The stress is obtained by dividing the maximum load that a cylindrical specimen can withstand under axial compression until failure by the cross-sectional area of the original specimen. force as compressive strength. Unless otherwise specified, the test is generally carried out at room temperature within the range of 10℃~35℃. For tests with strict temperature requirements, the test temperature should be 23℃±5℃. ......
