Abstract
In order to evaluate the measurement uncertainty of cement compressive strength,the GB/T 17671-2021 Test Method for Cement Mortar Strength(ISO Method)was used to measure the compressive strength of cement with a curing age of 3 days and 28 days.The measure-ment certificate of the testing machine and the resolution of force value display were collected,and the measurement uncertainty of cement com-pressive strength detection was evaluated.The results indicate that in the testing of cement compressive strength,molding and curing should be strictly carried out in accordance with the standard requirements.The testing machine should be regularly verified/calibrated,and when the testing frequency is high,periodic verification should be carried out to ensure the accuracy of cement compressive strength testing results.关键词
