Influence of Ultrasonic Treatment of Cement Paste on Physical-Mechanical Properties of Cement Compositions

The article presents the data on the impact of activation of mixing water and ultrasonic treatment on the kinetics of heat emission and time of setting of cement paste as well as on the strength of cement-sand mortar. It is shown that increasing the intensity of ultrasonic impact reduces both the beginning of setting and the end of setting of cement paste. The joint combination of mixing water activation and ultrasonic treatment of the modified cement paste makes it possible to significantly improve the strength of mortar mixes. The kinetics of heat emission of cement paste mixed with activated water and subjected to the ultrasonic impact demonstrates the acceleration of processes of hydration and structure formation of cement stone that is of practical importance for monolithic construction.
