    High strength non shrink repair material

    Introduction of material

    High strength repair material is a kind of super early strength concrete structure repair material which is based on cement, high strength material (quartz sand) as the main aggregate, supplemented by polymer powder, high efficiency water-reducing agent, early strength agent, expansion agent, anti-segregation and other materials.

    High polymer quick structure repair material is artesian, fast hardening, early strength, high strength, no shrinkage, micro expansion; Non-toxic, harmless, no aging, no pollution to water quality and the surrounding environment, good self-densification, zuxiu and other characteristics.

    High strength repair material is a kind of high performance super early strength concrete structure repair material developed according to the characteristics of concrete structure damage.

    Material characteristics

    Super early strength: high early strength, can meet the requirements of rapid repair of concrete structure.

    No shrinkage: the repair material mixed with high-efficiency expansion agent, can prevent the repair material water loss shrinkage.

    Durability: inorganic mixture, corrosion resistance, aging resistance.

    Environmental protection: non-toxic, harmless, no corrosion to steel, no pollution to water quality and the surrounding environment.

    The technical requirements

    Technical requirements of high strength repair materials are shown in table 1
