What Is Heat-Resistant Fire Concrete?
Heat-Resistant Fire Concrete is a premium refractory castable made from high-alumina cement and carefully graded aggregates. Unlike ordinary concrete that cracks above 500℃, our Fire Concrete stays strong under extreme thermal shock, chemical attack, and abrasion — for decades.
Why Choose It?
- Withstands 1350℃ to 1600℃ without failure
- Easy to mix and cast — just like regular concrete
- Ideal for wet or dry environments
- Locally stocked in Colombo with nationwide delivery
