水泥胶砂强度的测定数据

水泥胶砂强度的检测，需要从抗折强度以及抗压强度这两个大的方面进行检测，确保其强度能够与建筑工程施工规定的标准要求相符合。水泥胶砂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《水泥胶砂强度检验方法(ISO）》，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GB175-2007《通用硅酸盐水泥》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")

The detection of cement mortar strength shall be conducted in two core aspects: flexural strength and compressive strength, to verify that the strength complies with the standard specifications stipulated in construction engineering. Cement mortar strength is a critical indicator for evaluating cement quality, and the detection work shall be strictly implemented in accordance with relevant standards to ensure engineering quality and safety.
According to the national standard GB/T 17671-2021 *Method for Testing Strength of Cement Mortar (ISO)*, the electric flexural testing machine DKZ-6000 and servo compression and flexural testing machine YDW-300C are used to detect the compressive strength and flexural strength of sampled cement mortars cured for 3 days and 28 days respectively. Three replicate tests are carried out for each sampled cement mortar, and the average value of the three individual test results is calculated. Finally, the tested items are judged to meet the requirements of GB 175-2007 *General Portland Cement*. The test is determined to be compliant if the average values of 3-day compressive strength, 28-day compressive strength, 3-day flexural strength and 28-day flexural strength all satisfy the corresponding standard limits. The 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),"Compliant with Standards")
