What are the construction methods of self-leveling cement? I believe most of them are unclear. Maybe you have been exposed to some or a few and don’t fully understand them. So let’s introduce to you the construction methods of cement self-leveling and take stock of the maintenance methods of cement self-leveling. ?
What are the self-leveling construction methods of cement?
First, the construction methods of self-leveling cement are: Which
1. Base layer treatment
Whether the original ground is smooth and whether there is sand? , sanding, cleaning. Achievements: dust-free, loose and smooth. If there is sand on the ground, it must be treated.
2. Application of sealing primer
For self-leveling of surface cement, this is An extremely critical step is to prevent the self-leveling bubbles in the surface layer from being too thin or too thick, which will cause corresponding quality problems, uniformity, and one to two layers. Glue the cracks with glass fiber cloth.
3. Mix
Add water to the self-leveling cement and mix. The whole process lasts for three to Stay still for about five minutes.
4. Roller coating on the ground
Use a special melon board to smooth it. The thickness is generally 4-6 mm according to product requirements. Grouting and smoothing.
5. Defoaming treatment
Use defoaming rolling to eliminate the self-leveling cement floor Soak treatment!
Second, take stock of cement self-leveling maintenance methods
After the construction is completed, conduct on-site inspections It is closed and the cement self-leveling floor that has initially set is naturally cured. Apply cement-based self-leveling professional sealer to clean the base layer. It must be clean and free of dust, grease and other impurities. Apply it evenly with a man-made fiber mop or other suitable tools, and allow 1-2 hours of drying time each time. It will be open to pedestrians 4 hours after all the climbs are completed. It can be used normally after 7 days.
Detection method:
Cement-based self-leveling material provides a wear-resistant surface layer , so the main factor that bears the vertical load is determined by the ground base. Therefore, the strength of the ground base must be tested, and the tensile strength of the concrete base must be greater than 1.0MPa. Also identify weak areas that need to be repaired.
Comprehensively and thoroughly inspect the base, and use a ground pullout strength tester to detect the pullout strength of the ground to determine the strength of the concrete base.
Generally, the test is carried out according to the base concrete pouring flow section. At least one point is tested in each flow section, and additional test points are added as appropriate depending on the ground conditions (one test data is available for every 300 square meters) ).
Use the ground pullout strength tester to detect the pullout strength of the ground. The pullout test process is as follows,
① Core drilling, use a Bosch electric hammer with a hollow drill bit with an inner diameter of 35mm to drill a hole about 10mm deep on the concrete floor.
②Adhere to the steel seat (round steel bonding head with an outer diameter of 35mm).
③Inspection, place the aluminum support on the steel base, screw the steel connector on the steel base, and then penetrate the Hilti drawing instrument . Tighten the handle of the puller until the steel base breaks the concrete.
④ Reading, read the data directly from the pulling instrument panel, and the obtained data is the tensile strength of the concrete floor.
⑤Record and compile data into tables and mark them on the floor plan.
What are the self-leveling construction methods of cement?
Summary: What are the construction methods of self-leveling cement? , taking stock of cement self-leveling maintenance methods, the above article has given you a detailed introduction. I hope that after reading this article carefully, it will be helpful to your work!
