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

本研究对大量使用浆状粉煤灰配制混凝土的配合比设计理论进行了探讨。1.证明我们的方法不需要大量使用高效减水剂。给出了粉煤灰浆液的稳定期。2.针对硅酸盐水泥掺量恒定的粉煤灰混凝土提出的计算公式适用于粉煤灰掺量恒定的粉煤灰混凝土。接下来，展示了混凝土的新方法及其配方，该混凝土始终具有与纯波特兰水泥混凝土相同的抗压强度，并且具有适当的水泥和粉煤灰含量组合。3.容易生产含有大量粉煤灰的混凝土在预拌混凝土厂
