It's as if everything can't be perfect, no matter how strong the function and how high-quality the product is. There are always shortcomings. Just as there are many precautions in the use of cement pipes for building materials, what taboos does it have? The following Wanxinlai will introduce us in detail.
The first is the obvious defects of cement pipes.
After the agglomerated mortar layer or concrete component is often under high temperature and hot conditions, the strength will be lost. This is because under high temperature conditions, calcium hydroxide in cement stones will differentiate; otherwise, some aggregates are under high temperature conditions Will also differentiate or swell.
In the case of high temperature for a long time, it is possible to use fire bricks to block and protect ordinary mortar or concrete. For higher temperatures, special heat-resistant concrete should be used for pouring, and a certain amount of finely-ground heat-resistant material can also be added to the concrete.
