Precautions for making concrete hardened floor in factory
Published: 2015/9/18 Author: Qi Feng Floor
Concrete hardened floor is a kind of floor that can reach Mohs's level 9, this floor can be very suitable for all kinds of places with high requirements for floor hardness, so I think a lot of machinery factories, electronics factories and other factories Large vehicles often pass through the ground, and they can be used as concrete hardened floors. In this way, there is no need to worry about the ground being unable to withstand the rolling of the vehicle.
Wuhan Qifeng Flooring Company is a professional concrete hardening floor construction company. It has a huge team, more than 500 construction workers, and advanced flooring machines. It has been doing flooring for more than ten years. The floor can be used well for up to 30 years, and sand problems will not easily occur during use. At the same time, the floor can reach Mohs 9 hardness, which can withstand the rolling of the vehicle. Now I will introduce to you the experience of Wuhan Qifeng Flooring Company in making concrete hardened flooring.
Matters needing attention for concrete hardening floor:
1. Floor drying: ensure that the penetrant and hardener are fully ground to the capillary pores of the concrete, which is conducive to the formation of the polysilicon layer.
2. Sufficient immersion time of penetrant and hardener (more than 4 hours): ensure the depth of the polysilicon layer.
3. Thoroughly clean the floor: no hardened material remains on the floor surface, which is good for the floor.
4, sufficient amount of penetrant and hardener: to ensure the depth of the polysilicon layer.
Requirements for concrete:
1. The intensity reaches above C25 (at least above C20).
2.Water-cement ratio is not higher than 0.4.
3. The slump of the concrete mixed on site should be no more than 5cm, and the slump of the pumped concrete should be no more than 12cm.
4. For the secondary concrete floor, the thickness of the surface layer should not be less than 5cm.
5. In order to achieve better results, Qifeng company recommends adding reinforced mesh in the concrete (rebar diameter should be> ∮16).
6. The formed concrete can be divided into blocks for unlimited time polysilicon treatment. The cycle is short, the construction is flexible, and the normal temperature can be used for construction when the ambient temperature is greater than 0 degrees.
