- Scope
- This standard specifies the instruments, materials, mortar composition, test conditions, operation steps and result calculation of the cement mortar strength test reference method. Its compressive strength test result is equal to the ISO679 result. At the same time, alternative standard sand and vibrator are also included. If there is any disagreement with the results after using the standard sand, the benchmark method shall prevail. This standard applies to the inspection of the flexural and compressive strength of Portland cement, ordinary Portland cement, slag Portland cement, fly ash Portland cement, composite Portland cement, and limestone Portland cement. When using this standard for other cements, the applicability of the provisions of this standard must be studied.
