METHOD FOR CONTROL OF SETTING AND HARDENING PROCESSES IN WATER-CEMENT SYSTEMS

摘要

FIELD: construction.;SUBSTANCE: invention is related to the field of construction, namely to the field of construction works with application of water cement systems, and may be used in construction and repair works with application of concrete or mortar based on water-cement mixture. Method for control of setting and hardening processes in water-cement systems includes mixing of cement and water with previous treatment of water with acoustic oscillations with frequency from 17.5 to 22.5 kHz until level of energy introduced in water is from 3.0 to 40 kW-hr per 1 m³ of water. Invention is developed in dependent clauses.;EFFECT: expansion of facilities for effect at water-cement mixtures in process of their setting and hardening.;8 cl, 9 ex
