Abstract

The invention discloses a geopolymer double fluid grouting material for road base reinforcement. The material is formed by mixing a component A and a component B in a weight ratio of 3: 1. The component A is composed of the following materials in parts by weight: 60-70 parts of blast furnace slag micro-powder, 6-8 parts of an alkaline excitant, 1-3 parts of a stabilizer and 10-30 parts of water; the component B is composed of the following materials in parts by weight: 7-20 parts of polypropylene glycol, 9-15 parts of water, 60-80 parts of water glass, 2-6 parts of sorbitol, 0.5-2.5 parts of a surfactant and 1-3 parts of a catalyst. The invention further discloses a preparation method of the geopolymer double fluid grouting material for road base reinforcement. The double fluid grouting material prepared by the preparation method is excellent in performance and low in cost.

Description

technical field [0001] The invention relates to the field of processing and manufacturing road grouting materials, in particular to a geopolymer double-liquid grouting material used for road base reinforcement and a preparation method thereof. Background technique [0002] At present, when there are cracks, subsidence, potholes and other diseases on the old asphalt pavement and voids on the cement concrete pavement, the commonly used shallow grouting materials for the pavement include: cement slurry and organic polymers. Cement-based grouting materials have poor fluidity and permeability, and are difficult to inject into the small pores of the structural layer. Their durability is poor, and they are prone to softening and secondary pumping after grouting; high-polymer high-polymer grouting can only fill the structural layer in the early stage Cavities, etc., the water sealing effect is more obvious, but the interlayer loose matter cannot be consolidated. After two or three y...
