水泥标号快速测定法的研究和应用,是基本建设战线长期以来迫切要求解决的课题。自1971年以来,我们进行了一系列试验研究,取得了成果。目前提出的利用水泥净浆强度发展曲线预测水泥标号的快速试验方法,操作简便,设备投资少,可以在12～24小时内预测水泥28天标准强度。当40℃养护时试验结果以95％的保证率,使误差在 The research and application of the rapid determination method of cement number is a topic that has been urgently required to be solved in the basic construction front for a long time. Since 1971, we have conducted a series of experimental studies and achieved results. Presently proposed rapid test method for predicting the cement number using the cement paste strength development curve is simple to operate, with less equipment investment, and can predict the cement standard strength for 28 days within 12 to 24 hours. When the test results are maintained at 40°C, a 95% assurance rate is used to make the error
