High-toughness geopolymer grouting material modified by ultra-high weight fibers and emulsified asphalt, preparation and application
The present invention relates to a high-toughness geopolymer grouting material modified by ultra-high molecular weight fibers and emulsified asphalt, and a preparation method and application thereof, wherein the grouting material comprises the following components in parts by mass: 4-12 parts of emulsified asphalt, 80-100 parts of a geopolymer, 103-126 parts of an alkali-activated solution, 2-3 parts of ultra-high molecular weight fibers and 30-35 parts of water. Compared to the prior art, the grouting material modified by ultra-high molecular weight fibers and emulsified asphalt is simple to prepare, has good fluiditygood, and matches well with road substrate; the good toughness and crack control capability of the ultra-high molecular weight fibers enables this novel grouting material to overcome the problem in durability of common geopolymer-based materials. The material of the present invention can be applied in filling voids beneath a slab of a cement concrete pavement and in the technology of non-excavation road reinforcement of a road base course and a subgrade of a high-grade highway.
