Solution for excessive temperature of cement pipe
The use of cement pipes is very common, but there are many problems in it. When using them, many problems must be paid attention to, and the high temperature of cement pipes often occurs. The high temperature of cement pipes will affect its construction performance , Rapid setting, large slump loss of concrete, and even easy to cause temperature difference stress of cement concrete, causing damage such as cracking of concrete. So how to deal with this problem? This article introduces in detail.
Strengthening the ventilation of the mill can take away a part of the heat, but according to the calculation of the heat balance of the mill, the heat taken away by the mill ventilation generally accounts for only 20% of the total heat removal of the mill. Strengthening the ventilation in the mill Although the temperature of the material can be reduced, the ventilation in the mill is constrained by the resistance of the system, air lock, air leakage, etc., and also by the fineness of the product. Therefore, by improving the ventilation in the mill, the There are certain limits to temperature.
After setting the mortar layer or concrete component, the strength of the cement pipe will be lost if it is often in a very high temperature environment, mainly because the calcium hydroxide in the cement pipe is under the high temperature environment. Will differentiate, in addition, some aggregates can also differentiate or swell in high temperature environmental conditions.
For long-term locations with very high temperatures, refractory bricks can be used to isolate and maintain general mortar or concrete. In case of very high temperatures, special heat-resistant concrete should be used for pouring. A certain amount of finely ground heat-resistant material should be added to the concrete. This is the solution to the excessive temperature of the cement pipe. I look forward to assisting you!
