BT-20 template paint has a hard, bright and full coating, water resistance and wear resistance, rust prevention and corrosion prevention, and is widely applicable to various concrete templates and steam curing environments.
Since 2000, this paint has been applied in concrete projects with over 2 million square meters of formwork.
It is suggested to establish a four party technical expert group of the design unit, the supervision unit, the owner and the construction unit to jointly study and approve the construction scheme of important parts, the application of new technologies, new processes, new materials and measures to create excellence.
The use of cold-rolled ribbed steel bars can save 30-40% of the steel in the plate reinforcement, and the economic benefits are relatively significant, saving 20-30% of the steel.

Their bonding strength with concrete is more than three times that of smooth steel bars.

Suggestions on rationalization of construction 1.
The template release agent for concrete construction is BT-20 template paint (long-term release agent).
The concrete formed by the paint film is in a marble like shape, flat and smooth, without pollution, and the surface pores of the concrete are reduced by more than 90%.
The cold-rolled ribbed steel bars are made of ordinary low-carbon steel or low alloy steel hot-rolled circular bars as the base material, and after cold rolling reduction, they are rolled onto their surface to form steel bars with three or two sides of toothed transverse ribs, with a diameter of 4-12mm.

It is recommended to use Sikaflex 15LM single component low modulus polyurethane joint sealant for window sealing, and Sikaflex 11FC single component polyurethane elastic sealant for bathroom waterproof joints
.
The use of GS-32 mortar additive for wall masonry is no longer allowed in the country.
2.
After multiple engineering practices, it has been proven that the use of GS-32 mortar additive can effectively solve the problem of wall cracks.

It is recommended to use cold-rolled ribbed steel bars instead of HPB235 steel bars for cast-in-place floor slabs.
5.
However, when using other masonry materials, there is a problem of common quality problems, which is that the wall is very prone to cracks.
It has three main functions: (1) protecting the template from wear and tear; (2) Improving the appearance quality of concrete can achieve the effect of plain concrete; (3) Long acting release agent.
