Problems solved by technology

The second is that the newly formed minerals are attached to the surface, blocking the pathway of active ion reaction, so that the reaction speed is quickly slowed down or the reaction cannot be carried out.
Second, minerals such as aluminosilicate, silicate, and aluminate gel are attached to the surface of fine slag particles (causing coking and blockage poisoning), and it is difficul

Abstract

A disclosed alkali-activated grouting material is prepared from the following raw materials in parts by weight: 40 to 60 parts of slag powder, 30 to 40 parts of water glass, 100 to 200 parts of high-iron sulphoaluminate cement, 20 to 30 parts of sodium bentonite, 20 to 30 parts of lithium carbonate, 10 to 20 parts of citric acid, 10 to 20 parts of graphene oxide, 20 to 60 parts of sodium hydroxide, 10 to 30 parts of sodium alginate and 20 to 40 parts of silicon dioxide. Sodium hydroxide and sodium alginate are added, so that the slag powder can be excited to form a novel gel material, and the breaking strength and the compressive strength of the novel gel material are improved.

Description

technical field [0001] The invention belongs to the field of grouting materials, in particular to an alkali-activated grouting material. Background technique [0002] Alkali-activated gelling materials use the catalytic principle of alkali activators. Alkali activators can catalyze the hydration of slag and speed up the hydration reaction of slag, but the hydration reaction speed slows down or basically termination. The reason for slowing down is that the alkali activator (catalyst) participates in the reaction to generate new minerals, causing the activator (catalyst) to be permanently lost and the active ions to be greatly reduced. The second is that the newly formed minerals adhere to the surface, blocking the pathway of active ion reaction, so that the reaction speed is quickly slowed down or the reaction cannot be carried out. Specifically, firstly, the reaction between slag and stimulator will generate low-calcium silicate, aluminate, and aluminosilicate gel, and alu...
