The study on manufacture of early strength cement composite materials
Abstract：There is bad effect for early strength （3 d） of cement when partial solid waste material is used to cement admixture individually, which may restrict the use of cement. For this purpose, fly ash, mineral powder, limestone powder, and red mud were chosen to replace cement with constant quality with proportion of 5, 10, and 15 percent separately, firstly. On this basis, the proportion of red mud was fixed to 5 percent and the total proportion of mixture was fixed to 15 percent, and fly ash, mineral powder, and limestone powder was mixed with red mud. The influences of composite admixture on 3 d, 28 d strength of cement were studied. The results show that two groups of composite admixture can improve strength of 3 d and 28 d, which are 10% mineral powder and 5% red mud, and 5% fly ash, 5% mineral powder, and 5% red mud.
