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.

The invention relates to the use of a multi-component composition comprising A) a polyol component (A) comprising at least one polyol and water, B) a hardener component (B) comprising at least one polyisocyanate, and C) a solid component (C) comprising a hydraulic binder and one or more aggregates, as an early water resistant construction or repair material for constructing, repairing or refurbishing component parts, wherein the mixed and applied multi-component composition is immersed in water not later than 8 hours, preferably not later than 2 h, after application. The use as an early water resistant construction or repair material is especially suitable for component parts, which are in contact with water during operation such as offshore wind energy plants or water retaining systems, e.g. pipelines.

Disclosed herein are concrete and asphalt crack filler compounds and methods for utilizing them. According to some embodiments, a method of utilizing one of the compounds can include the steps of (1) obtaining a surface crack filler compound, (2) depositing the surface crack filler compound into a surface crack (e.g., concrete, asphalt, etc.), and (3) depositing water onto the surface crack filler compound to cause the surface crack filler compound to solidify and fill the surface crack. Additionally, and according to some embodiments, the method can further include, prior to depositing the surface crack filler compound into the surface crack: removing debris from the surface crack using at least one of a brush, pressurized air, or pressurized water.
