What is heat-resistant concrete?

It can be used in thermal engineering with working temperature below 600℃ and can be made into concrete with strength as high as 50MPa. This kind of concrete is suitable for producing concrete components in small concrete precast plants, but it is not suitable for use in construction sites. In China, slag coagulation was popularized in 1959. After long-term use and testing, most of them are of good quality. Slag concrete is a kind of lightweight thermal insulation concrete with slag instead of sand, stone aggregate and cement.
