RESEARCH OF THE STRENGTH OF CEMENT STONE BASED ON THE WATER VAPOR CONDENSATE OF FLUE GAS

Abstract

The production of cement causes significant emissions of greenhouse gases, in particular CO2, which leads to global warming. The development of methods of disposal of these ages is an urgent task. The paper examines the possibility of using steam condensate from the flue gases of cement production as a raw material for obtaining cement stone. The mechanical characteristics of the cement stone made with the use of flue gas vapor condensate and in accordance with the characteristics of the cement stone made on tap water were determined. It was established that the cement stone obtained with the use of steam gas condensate has the best mechanical properties. The resulting cement has higher flexural strength than tap water cement, and cement stone has higher flexural and compressive stresses. At the same time, the fragility of cement stone made from mixed condensate of flue gas steam remained the same as in cement stone made using tap water.
