Large-caliber cement pipes have brought us a lot of convenience in our days, so the amount of demand in urban construction is very large, but the phenomenon of cracks often appears in use, in order to be used in urban construction, Therefore, we have to deal with the pipeline showing cracks, but how to deal with it in detail, I will tell you a detailed treatment method below.

First, we must effectively control the internal heating rate of concrete. We can mix the appropriate amount of mineral fly ash in the production of concrete to slow down the release rate of hydration heat. Second, we can control the temperature of the raw materials. The tube is circulated with water to release the heat of hydration.

When the concrete is cracked, we usually use cement paste or low viscosity polymer to seal it to prevent water intrusion; if the crack is deep or wide, we use pressure grouting to repair it.
