Micro-spherical hydration heat regulating agent as well as preparation method and application of micro-spherical hydration heat regulating agent
The invention provides a micro-spherical hydration heat regulating agent which is prepared by carrying out polymerization and crosslinking reaction on dextrin, a crosslinking agent and a dispersing agent in the existence of a redox initiator, wherein the mass of the crosslinking agent accounts for 1-5% of the mass of the dextrin, the mass of the redox initiator accounts for 1-3% of the mass of the dextrin, and the mass of the dispersing agent accounts for 1-3% of the mass of the dextrin. The invention also provides a preparation method and an application of the micro-spherical hydration heat regulating agent. The regulating agent is prepared by carrying out crosslinking modification on the dextrin, is of a spatial net structure and is high in acid, alkaline and shear resistance and capable of effectively reducing the peak value of the hydration heat release rate and improving the compressive strength of concrete.
