粉煤灰复合矿物外加剂的研制

Preparation of compound mineral admixture for fly ash

本文利用化学活化和物理活化相结合的原理 ,研制出一种复合型混凝土矿物外加剂 ,通过有效激发粉煤灰的活性 ,利用粉煤灰可以作为胶结材的性质 ,取代部分水泥 ,在满足使用要求的基础上大幅度降低水泥用量。

In this paper,a compound mineral concrete admixture is prepared by utilizing the principle of combining both chemical and physical activation.Part of cement can be replaced by effectively activating fly ash activity and utilizing the property that fly ash can be used as a binding material,thus the cement demand can be greatly decreased while the use requirement can also be met.
