Precautions for Construction of Concrete Pipe Machines
Here are some considerations for the construction of concrete pipe machines:
1. It is an important condition to ensure the durability of cement pipe equipment that better sand and stone aggregates with good sand and rock aggregate quality and qualified technical conditions are used.
2. For a reasonable selection of cement varieties, cement varieties with high strength and durability should be selected. According to the conditions of the use of cement pipe-making machinery, the corresponding cement varieties with special properties should be selected.
3. Appropriately control the water cement ratio and cement consumption of cement pipe making machines. The ratio of water to cement is the main factor that determines the compactness of concrete. It not only affects the strength of concrete, but also seriously affects its durability. Therefore, it is necessary to strictly control the water ash. ratio. Ensuring a sufficient amount of cement can also serve to increase the compactness and durability of the concrete.
4, mixed with air-entraining agent or water reducer. The addition of air-entraining agents has a good effect on improving the performance of impermeability, antifreeze, etc. In some cases, it can also save cement.
5. Improve the construction and operation methods of cement pipe making machinery. In the concrete construction, the cement should be evenly mixed, irrigated and vibrated densely and reinforced to ensure the construction quality of the cement pipe making machine.
