| 摘 要： | 通过大量试验发现,采用P.O42.5水泥作为基准水泥试验时(用同一种矿渣粉试验样品),矿渣粉的早期活性值要比采用P.I52.5水泥为基准水泥时的早期活性值大很多,3d和7d抗压强度前者比后者高,但28d抗压强度后者却又赶上甚至超过前者。透过此现象,深入分析它的产生机理,为实验单位如何选取基准水泥及基准水泥的生产提供了参考。

| Abstract: | Through a large number of tests, we have found when we adopt 425# portland cement as reference (using the same sample of finely- pulverized blast- furnace slag), slag powder’s early activity value will be big- ger than that of 525# Portland cement as reference. 3- day compressive strength and 7-day compressive strength of the former are higher than the latter, but the 28- day compressive strength of the latter is yet bigger than the former’s. We have analyzed the mechanism of this phenomenon. It will be a r... |
