Stabilzation Theory for Slurry made of Lnorganic Powders as Mineral Admixture for Concrete

本研究探讨了在混凝土中大量掺入浆体状粉煤灰的配合比设计理论。1.论证了本方法不需要大量使用高效减水剂。给出了掺入等硅酸盐水泥掺量的粉煤灰混凝土的稳定化周期。在此基础上，给出了在水泥和灰分配合比适当的情况下，使普通硅酸盐水泥混凝土保持相同抗压强度的新方法及其公式。3.在预拌混凝土厂生产大掺量的粉煤灰混凝土容易产生

In this study, mix design theory for large quantity use of coal ash in the shape of slurry into concrete was discussed.1.It was certified that large quantity use of superplasticizer is not required by our method. The period of stabilization of coal ash slurry was shown.2.The formula that was presented for the concrete containing coal ash with constant Portland cement content was shown to be applicable to the concrete containing coal ash with constant powder content. Next, the new method and its formula for the concrete that always performed the same compressive strength to the Portland cement only concrete with the appropriate combination of the cement and coal ash content were shown.3.Concrete containing large quantity of coal Ash was easily produced in ready-mixed concrete plant
