Problems solved by technology

[0003] However, in the prior art, when steel slag powder and slag powder are used to replace cement clinker, in order to make the concrete meet the specifications, a large amount of slag powder and a small amount of steel slag powder need to be used, so that the utilization rate of steel slag is very low, and excessive use The use of slag powder makes the actual production cost higher, which leads to the problem of high production cost when using steel slag to produce cementitious materials

Abstract

The invention belongs to the technical field of gelling materials, and provides a gelling material for a building and a preparation method. The gelling material for the building is prepared from the following ingredients: composite steel slag powder, composite mineral slag powder, waste gypsum, geopolymer, polyethylene fiber, NS-780 redispersible latex powder, an exciting agent and an adjuvant, the various ingredients are combined into a formula of the gelling material in a certain weight ratio, in a gelling agent prepared by the formula, the dosage of steel slag is increased, the dosage of mineral slag is decreased, and meanwhile, as the waste gypsum, the geopolymer, the polyethylene fiber, the NS-780 redispersible latex powder, the exciting agent and the adjuvant are added, the performance of the gelling material is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of gelling materials, and in particular relates to a gelling material for construction and a preparation method thereof. Background technique [0002] In the prior art, steel slag has certain gelling properties due to its chemical composition and phase composition being similar to ordinary silicon cement clinker. Steel slag is used as fine aggregate, and steel slag powder and slag powder replace cement clinker to prepare cement cement to produce products. Concrete with stable performance and good workability enables steel slag to be utilized and improves the utilization rate of steel slag. [0003] However, in the prior art, when steel slag powder and slag powder are used to replace cement clinker, in order to make the concrete meet the specifications, a large amount of slag powder and a small amount of steel slag powder need to be used, so that the utilization rate of steel slag is very low, and excessive u...
