From loading angle, the material that pours into the pressure zone through crack is higher to the compressive strength requirement of material self.For example: the compressive strength of epoxy resin cured product is 〉=40MPa that cement material 28d is 〉=60MPa therefore, to pour into cement material favourable.
Chemical material is a kind of macromolecule slurry material, solidify later intensity and durability not as good as inorganic material, and price is high.For improving the durability of building, reduce engineering cost, it is useful adopting inorganic material.
Usually, polymer chemistry slurry material more or less has some toxicity, and human body and environment are more or less had some injuries and pollution, is Harm reduction, environment pollution, and it is useful adopting inorganic material.
By the reasonable Arrangement of drilled grout hole, cementation can realize in the hole, circumfusion in seam, more is conducive to stitch interior filling full, closely knit, and set strength is higher.Chemical grouting material circulation can make slurry temperature rise aggravation, and viscosity increases and uniform velocity quickening time of setting, is unfavorable for the abundant diffusion of slurries, if implode occurs, will cause plugging, plug-hole and block the accident such as seam face.
Chemical grouting material is sewed with higher selection requirement to wetting.Due to wet seam, do not reach the functional requirement that recovers construction after even chemical grouting material can not pour into or pour at all.Cement grouting material can effectively solve this technical barrier.
