粉煤灰细水泥的配制及浆液性能的研究

Study of the formula and the performance of fly ashes-fine cement mortar

本文通过试验得出 ,以粉煤灰为主要原料 ,加入一定的外加剂 ,可以配制出适合表土层注浆的、细度大于 45 μm占 9%的、强度满足 42 5 #水泥强度的细水泥。该水泥也可以用作其它建筑物的低热水泥。

According to the test, a kind of cement mortar applied to flooding in alluvium can be formulated by using fly ashes mainly and amount of additional preparation. The radius that great than 45μm only occupied the total of 9%. The strength of this fine cement can get the degree of the strength of 425 # cement and can be instead of the other low heat cement.
