Large-caliber cement pipes have brought us great convenience in our lives. Therefore, the amount of demand in urban construction is very large, but the phenomenon of cracks often occurs in use. In order to be used in urban construction, Therefore, we have to deal with the cracked pipeline, but how to deal with it in detail, the next editor of the cement pipe manufacturer will tell you a detailed treatment method.
First, we need to effectively control the heating rate inside the concrete. We can mix the appropriate amount of slag in the concrete production to slow down the release rate of hydration heat. Second, we can control the temperature of raw materials. The cooling pipe is connected to the circulating water to release the heat of hydration.
When cracks have appeared in the concrete, we usually use cement paste or low viscosity polymer for sealing to avoid water intrusion; if the cracks are deep or wide, we should use pressure grouting to repair them.
