Thermal Ceramics FireMaster Firecrete 125
Categories:	Ceramic
Material Notes:	Firecrete 125 is used on the floor of fire training facilities and harsh outdoor burn applications. It is a dense refractory concrete which incorporates an intermediate-purity, calcium-aluminate cement, giving high strength and abrasion resistance. It also offers superior thermal shock resistance when exposed to hose stream conditions at high temperature. This performance is achieved by the incorporation of RFT (Rapid Fire Technology) and stainless steel fibers. Features: Superior thermal shock resistance, which provides spall resistance Lightweight Low thermal conductivity High strength Abrasion resistance Information provided by Thermal Ceramics Data has not been recently verified. Please contact manufacturer for current information.
