What is the difference in composition between refractory cem
Refractory cement and ordinary cement are both materials used for masonry, but there are big differences between the two. The main difference is high temperature resistance.
1.
Refractory cement is a kind of
refractory material. It is made of high temperature resistant materials, such as alumina, calcium oxide and silicon oxide. It can withstand extremely high temperatures and usually has good fire resistance and wear resistance above 1000°C. and corrosion resistance. Compared with ordinary cement, refractory cement can still maintain good structural stability and strength at high temperatures, thanks to its special high-temperature resistant composition design.
2. Ordinary cement is mainly a material used for building masonry. It is mainly made of limestone, clay and gypsum. It can withstand low temperatures, usually below 100°C, and has good bonding strength and durability. Its basic chemical component is calcium silicate, which has good hydraulic hardness, that is, it can harden in water and reach a certain strength.
