1980年以来,我们结合水泥软练方法新标准的实施,本着需时短、准确可靠、设备简单、便于推广的要求,在分析烘烤法、沸煮法等预测水泥标号试验结果的基础上,进行了“胶皮闭模湿热法”预测水泥标号的试验,试验周期为九小时。通过对40个水泥厂不同水泥品种,标号为325～525号的53个水泥样品试验数据的统计回归分析:九小时“胶皮闭模湿热法”预测水泥标号不仅与标养强度的相关关系密切,而且复演性好。是快速预测水泥软练标号的一种有效方法。一、材料、设备及试验步骤 Since 1980, based on the implementation of the new standard for cement soft training methods, based on the requirements of short-term, accurate and reliable, simple equipment, and easy popularization, we will analyze the test results of cement labeling, such as baking method and boiling method. , Conducted the test of cement labeling with the “mold closed hot-damp method”. The test period is nine hours. Through the statistical regression analysis of test data of 53 cement samples with different cement types in 40 cement plants, numbered 325-525: the nine-hour “rubber skin closed-mold damp heat method” predicts that the cement label not only has a close relationship with the standard strength. And the recurrence is good. It is an effective method for quickly predicting the softness of cement. First, materials, equipment and test procedures
