Cement hydration rate regulating material as well as preparation method and application of cement hydration rate regulating material
The invention provides a cement hydration rate regulating material which is a dextrin and starch composite structural material, wherein the mass percentage of starch is 0.5-60%, preferably 1-25% and more preferably 1.5-10%. The cement hydration rate regulating material is simple in preparation process and low in cost; and the cement hydration rate regulating performance of the cement hydration rate regulating material is greatly improved as comparison with that of the prior art. Meanwhile, the cement hydration rate regulating material can generate a cement hydration influence different from that of the traditional micromolecular retarder; the regulating material has few and even no influences to the induction period of hydration, but can be used for greatly reducing hydration rates in an acceleration period and a deceleration period; however, the traditional micromolecular retarder is mainly used for prolonging the induction period for cement hydration, but has no influences to the hydration rates in the acceleration period and the deceleration period of the cement hydration.
