Title of the articleThe study of character of cement stone neoplasms during the hardening in the presence of carbonate filler
Abstract.Application of the fine ground mineral fillers is one of the effective ways to improve the physical and mechanical properties of mixed binders and influence on the processes of structure formation of cement stone. However, the use of natural additives-fillers leads to additional costs for their production, transportation and grinding. As a substitute for natural mineral raw materials in mixed binders it is proposed to use the carbonate sludge of water softening. In this paper we studied the effect of carbonate filler from water softening sludge on processes of hydration of cement compositions and character of neoplasms arising in their hardening. It is established that, when introduced into the cement sludge of the carbonate solution increases the degree of hydration of the clinker minerals, is increased the amount of the calcium hydrosilicates and produced hydrocarboaluminates calcium. It has been shown that it promotes prolonged strength during hardening of the cement stone.
Keywords.Mixed binder, additives, fillers, hydration of clinker minerals, structure of cement stone, sludge water softening.
