Abstract: Disclosed are a multifunctional cement hydration heat control material and a manufacturing method therefor. The cement hydration heat control material in is a comb polymer having three side chain structures, the three side chain structures are respectively a carboxyl group, a sugar alcohol group, and a polyether structure, and the main chain of the polymer is a carbon chain structure formed by free-radical polymerization of a double bond in a double bond compound monomer. The multifunctional cement hydration heat control material can achieve integration of cement hydration heat control performance, water reduction performance, and shrinkage reduction performance in a same molecule, can achieve control focusing on a performance by means of structural adjustment, does not need multi-component compounding during use, and is more convenient. The control material is non-toxic and water-soluble, can be made to have an appropriate concentration, and is convenient to use.

Abstract: Disclosed are a method for separately preparing light magnesium oxide and calcium oxide by using dolomite and an application thereof in preparation of a calcium-magnesium composite expanding agent. In the method for preparing light magnesium oxide and calcium oxide, based on the difference in decomposition temperature between magnesium carbonate and calcium carbonate during the calcination and decomposition of dolomite and the difference in the weight of the materials after decomposition, the effective separation of magnesium oxide and calcium oxide is realized by a one-step method, thus separately preparing light magnesium oxide and light calcium oxide. The calcium-magnesium composite expanding agent is prepared by using the foregoing light magnesium oxide and calcium oxide. On the one hand, the present invention solves the problem of the limited origin of the light magnesium oxide raw material of the magnesium expanding component in the calcium-magnesium composite expanding agent.
