水泥抗折抗压强度的测定数据

水泥抗折强度以及抗压强度这两个方面的检测，确保其强度能够与建筑工程施工规定的标准要求相符合。水泥抗折抗压强度是评价水泥品质的重要指标，应严格按照相关标准进行施工，以确保工程的质量及安全。按照国家标准GB/T17671-2021，运用检测设备电动抗折试验机DKZ-6000、伺服抗压抗折试验机YDW-300C对分别凝结3天和28天的抽样水泥胶砂进行抗压强度以及抗折强度的检测，每个样品水泥胶砂分别进行三次检测，计算出三次单块值的平均值，最后判定所检项目符合国家标准标准要求，当3天、28天的抗压强度以及抗折强度的检测平均值同时满足标准，则判定为符合，公式如下：Fx=IF(AND(3天抗压强度平均值>=17,28天抗压强度平均值>=42.5,3天抗折强度平均值>=3.5,28天抗折强度平均值>=6.5),"符合标准")This dataset focuses on detecting the flexural and compressive strength of cement to ensure that its strength meets the standard requirements specified in construction engineering. The flexural and compressive strength of cement are important indicators for evaluating cement quality, and relevant standards must be strictly followed during testing to ensure engineering quality and safety. According to the national standard GB/T17671-2021, the flexural and compressive strength of sampled cement mortar specimens cured for 3 days and 28 days respectively were tested using the electric flexural testing machine DKZ-6000 and the servo-controlled compressive and flexural testing machine YDW-300C. For each cement mortar specimen, three replicate tests were conducted, and the average value of the three individual test results was calculated. Finally, the tested items are judged to meet the national standard requirements. The compliance judgment is passed only when the average values of 3-day compressive strength, 28-day compressive strength, 3-day flexural strength, and 28-day flexural strength all meet the standard thresholds. The judgment formula is as follows: Fx=IF(AND(3-day compressive strength average ≥17, 28-day compressive strength average ≥42.5, 3-day flexural strength average ≥3.5, 28-day flexural strength average ≥6.5),"Complies with Standard")
