Cement pipe manufacturers explain the price of concrete drainage pipes and the reasons for cracks. Cement pipe is one of the important large-scale equipment in the day, its function is very strong, and the price has also shown fluctuations in recent years. Next, the manufacturer will talk about the price of the cement pipe and the reasons for the cracks.
1: Causes of cracks on concrete surface
Most of the cracks on the concrete surface are caused by shrinkage, and they can be divided into two categories: one is that the moisture on the surface of the concrete that has just been poured is evaporated and dried. The humidity is small, so its surface will evaporate and dry, but its interior is still a plastic body, which causes cracks to occur.
The other type is caused by the internal and external temperature difference of the concrete caused by the hydration heat during the hardening of the concrete. For the deeper concrete, during the pouring of the upper concrete, it will continuously settle due to its own weight. Then when the concrete begins to set but does not finish set When suffering from the reinforcement bolts or the joint bolts of the formwork, this settlement will be blocked and cracks will occur.
2: Treatment of concrete surface cracks
First, we need to control the internal heating rate of the concrete effectively. We can mix the right amount of fly ash in the production of concrete to slow down the heat release rate of hydration. Second, we can control the temperature of the raw materials. The cooling pipe is circulated with water to release the heat of hydration.
When concrete is now cracked, we usually paint it with cement slurry or low-viscosity polymer to avoid water intrusion; if the crack is deep or wide, use pressure grouting technology to repair it.
In modern urban sewer pipes, cement pipes are often used, and the price of cement pipes is now a matter of great concern to people.The use of cement pipes has brought many advantages to our production days, so the price of cement pipes how?
In urban construction, cement pipes are generally used to clean sewage pipes. The price of cement pipes is calculated in meters. Of course, the price per meter of cement pipes of different materials and uses is different. But regardless How does its price change, its basic use is unchanged, and its use method will not change.
When using a cement pipe, check it before construction to ensure that each part is normal, and the connection between each hose is safe and reliable. Then use it to install the unit. It is also necessary to strictly observe the setting of each parameter and not to overload it. If it is overloaded, it may easily cause the cement pipe to crack, and the consequences are very serious.
After the introduction of the price of the cement pipe and the reasons for the cracks, I believe that we have learned a lot. If you have any questions you want to know, you can come to us. Our company focuses on producing various cement pipes for many years. Diverse and affordable, everyone is welcome to come to our company to buy.
