Study and Application of the Xonotlite Based Calcium Silicate Material

Among the heat insulating materials for fumaces and high temperature pipeline, xonotlite based calcium silicate has the best cost performance. With an activaion technique (wet grinding with an activator), its bulk density may be reduced, its strength may be incnaed and its heat resistance may al-so be greatly enhanced. Thus, the cost performance may be more optimized.Ih this paper, the results of the optimization experiments on raw materials, mixture proportions,technical paramters are presented, the basic properties of its pilot scale product are compared with those of conventional ones. In addition, the mechanism of its optimization is discussed with the SEM and XRD technique.
