Abstract

The invention discloses a method for regulating and controlling the dissolution rate of tricalcium silicate in an erosive ion environment. According to the method, nano sol is added into tricalcium silicate in an erosive ion environment containing magnesium ions and chloride ions, and ultrasonic catalysis is assisted, so that the dissolution rate of tricalcium silicate is regulated and controlled, a hydration system of the cementing material is stabilized, the influence of erosive ions on early dissolution and long-term durability of the cementing material is relieved, and the service life of the cementing material is prolonged. The application of the cementing material in ocean engineering is facilitated.
