What are the differences between refractory cement and ordin

Although refractory cement and ordinary cement are both cements, they have significant differences in composition, pressure resistance and shrinkage rate. These differences determine their unique use values ​​and limitations.
1. Different chemical compositions: The composition of refractory cement contains high-temperature-resistant oxides, which gives it excellent high-temperature resistance. In contrast, ordinary cement contains mainly silicates and its properties are relatively conventional.
2. Different compressive strengths: Refractory cement tends to perform better, especially in high temperature environments, and its strength remains more stable.
3. Different shrinkage rates: In terms of shrinkage rate at high temperatures, refractory cement is also far superior to ordinary cement. Its shrinkage rate is smaller, which helps maintain the stability of the structure.
