Crack repair grout of concrete, its manufacturing method, injection method and using the same

摘要

Even for cracks of fine concrete of 100μm or less, high permeability can be obtained, crack repair grout of concrete with a durability and water sealing excellent effect, a method of manufacturing the same, and of the injection method using the same It is an object of the present invention to provide. Silica fine particles, dispersing agents, and the material A that contains water, calcium compound having a mean particle size of 1.0μm or less, dispersing agent, concrete and consisting of a B material containing water average particle size of 1.0μm or less crack repair injection material, calcium compounds, high-speed stirrer, media agitating mill, and the injection material is calcium hydroxide, calcium compound particles and / or silica is selected from the group consisting of grinding machine using a high pressure water The injected material is one which is produced using one or more kinds are, the injection material which comprises a polymer dispersion Moreover, the injection material which comprises a curing time adjusting agent, of the grout production process, as well as a configuration injection method using the same.
