Cast-in-place floor (ceiling position) Reinforcement protective layer is not enough, local steel exposed. I intend to use epoxy resin mortar
If not skilled, epoxy resin mortar is not good to paint. And grass-roots bonding is a problem, the level of skilled workers is also a problem.
Suggest,
1, steel rust to be completely, or the same burst open;
2, carbon fiber reinforcement approach, that is, epoxy resin plus fiberglass cloth, professional construction. Quality assurance, the effect is much better than their own configuration of epoxy resin mortar. In addition, crack prevention. This method of handling is a formal approach that can be changed by design.
3, the surface putty putty, it is finished.
I have dealt with a variety of cracks blocked, fill, closed. And epoxy mortar of the prestressed anchor head and structural reinforcement. Specification of epoxy coated steel bars, the anchorage length should be increased, the correction factor is 1.25 see GB50010-2017. Can be seen that the surface is more smooth and easy to erosion.
Epoxy resin 100, curing agent ethylenediamine 8, toughening agent dibutyl phthalate 12, diluent acetone amount. Epoxy resin warm water bath after adding toughening agent, diluent stir well, before the application of curing agent and cement appropriate, stir well, run out again. After the paint is scratched with a scraper, it is finally taken with a hair dryer (hairdressing).
