Embodiment 1
[0037] The magnesia high-performance anti-cracking agent for concrete provided in this embodiment, its raw materials include lightly burned MgO clinker 54wt%, phosphorus slag 31wt%, cinder 10wt%, quartz sand 2wt%, calcium chloride 2wt%, new heat of hydration Absorbent 1wt%;
[0038] The preparation method of the novel heat-of-hydration absorbent is:
[0039] S1. the maleic anhydride and sodium thiocyanate that the molar ratio is 7:1 are mixed, add the water of 1.5 times of the total mass of maleic anhydride and sodium thiocyanate to be mixed with solution;
[0040] S2. under the atmosphere of nitrogen, be that the sodium benzenesulfonate solution of 32% is added dropwise in the solution of S1 gained by mass percent concentration, stir while heating while dropping, the quality of the sodium benzenesulfonate that is added dropwise is 0.5% of the total mass of the reaction solution; the temperature is raised to 60° C., the reaction is kept for 2 hours, and the novel hydration he...
