Among which the experiment group using 50% fly ash, 10% silica fume instead of ordinary Portland cement shows rather better durability either in standard curing or the accelerated aging experiment.
Result show that the hydration of cement is accelerated by limestone flour at early ages.
结果表明:在水化早期,石灰石粉加速了水泥的水化。

The problem of accelerated setting of SAAS cement was solved by a series of tests. Retarding mechanism of the new cement was discussed and rational technical method was proposed.
