Deal with concrete with epoxy grout roots rotted construction preparation!

Parts of concrete column mild roots rotted phenomenon, can be patched by the method of grouting, epoxy grout material using concrete, the construction process is: the old concrete cut hair to wash saturated, perfusion, daub and perfusion slurry curing. Construction of concrete measures are as follows: a, basal processing ( 1) Cut hair. In order to ensure the epoxy grout and basement concrete has good bonding, wire brush or sand blasting method to remove surface dirt floating layer ( With paint or grease contamination with acetone rinse) 。 Such as loose base level, should use artificial cut hair, cut off the damaged concrete, make the basement with hard and solid concrete surface, cut hair must be thoroughly, but also shoulds not be too much depth, in order to avoid damage to the concrete. ( 2) Washing and saturated. The chisel in addition to the surface of the concrete, using water cannon ( Adopts tap water) Will rinse clean debris, dust and continuously and evenly spraying, the concrete surface layer reach saturation state, and the surface without MingShui. Second, the configuration of the epoxy grout epoxy grout and the amount of water in accordance with the provisions in the material barrel mixer is used to move slowly from side to side, up and down fully stir well, and mixing blades shall not to liquid level, so as to avoid mixed with air bubbles. Consistency to determine according to the need of site construction. Finished product grouting, with large fluidity, no shrinkage, early strength and high strength ( 28 days to 55 mpa) Such as performance, can satisfy the workability and strength requirement. www。 adssrrt。 com
