Abstract
The invention discloses a slag powder active agent based on dual-alkali desulfurization waste, a preparation method and application thereof. The slag powder active agent is composed of the following raw materials in percentage by weight: 65-80% of waste collected by double-alkali desulfurization; 1-12% of diethanol monoisopropanolamine; 3-12% of sodium thiocyanate; Alcohol polyoxyethylene ether phosphate 1-12%. The present invention creatively proposes for the first time that the waste collected by double-alkali desulfurization is used as the raw material of the slag powder active agent, so that waste resources can be turned into treasures, and the activation effect is good. cost, with great social and economic benefits.
Description
technical field [0001] The invention belongs to the technical field of cement production, and in particular relates to a slag powder active agent based on double-alkali desulfurization waste and a preparation method and application thereof. Background technique [0002] Slag powder is a good cementitious material, especially S105 high-grade slag powder has high activity. The concrete added with high-quality slag powder has high strength, good workability, and quick demoulding, which can improve the impermeability and frost resistance of concrete and increase slump. At present, the slag powder used in the market is less than the national standard S105, with a market share of less than 5%; the market share of S95 slag powder is only less than 35%, which cannot meet the needs of the construction market, especially the national key construction projects. The main reason for the low proportion of high-grade slag powder is that the activity index of slag powder is low, which cann...
