Abstract

The invention discloses a manganese residue-based concrete admixture function regulator and a preparation method thereof. The regulator is prepared by compounding the following raw materials by mass percent: 75%-85% of a mixture of a polyester polycarboxylate water reducer and a polyether polycarboxylate water reducer, 5%-15% of a composite active exciter, 1%-5% of a retarder and 1%-5% of a composite air entraining agent. When the function regulator is used, the working performance and the age strength of a manganese residue-based concrete admixture meet the requirements under high manganese residue mixing quantity, and the maximized utilization of manganese residues in concrete industry is improved; on one hand, the working performance of concrete is improved, and on the other hand, the concrete strength is ensured through modifying the activity of the manganese residue-based concrete admixture.

Description

technical field [0001] The invention relates to a manganese slag-based concrete admixture function regulator and a preparation method thereof, in particular to a composite admixture for adjusting the working performance of a fresh manganese slag-based concrete admixture and the strength of a hardened steel slag-based concrete admixture. Background technique [0002] The commonly used concrete admixtures are cement, fly ash and mineral powder. Fly ash is a fine powder collected from the flue gas of boilers that burn pulverized coal. Among them, low-calcium fly ash is currently the largest and most widely used concrete admixture at home and abroad. At present, the development of mineral resources is limited, so that the resources of fly ash and mineral powder are facing an increasingly scarce state. [0003] With the mining of manganese ore and the development of manganese products, the manganese slag after production has become a major problem in rational disposal. The man...
