耐熱セメントと普通セメントの違い

The main differences between heat resistant cement and ordinary cement are high-temperature resistance, 構成, 物理的および化学的指標, と適用機会. 耐火セメント is high temperature resistant, 高強度, low shrinkage, and suitable for high temperature and corrosive environments; ordinary cement is used in the construction field, with high bonding strength and good durability. The two have their own characteristics and cannot be replaced by each other.

The difference between high-temperature-resistant cement and ordinary cement

Different ingredients

Refractory cement is a refractory material made of high-temperature resistant materials such as alumina, calcium oxide, and silicon oxide that can withstand extremely high temperatures, usually above 1000°C, with good fire resistance, 耐摩耗性, 耐食性.

Ordinary cement is a material mainly used in building masonry. It is mainly made of limestone, 粘土, and gypsum. It can withstand low temperatures, usually below 100°C, and has good bonding strength and durability.

There are differences in physical and chemical indicators

Different chemical composition

Refractory cement contains high-temperature resistant oxides in its composition, which makes it have excellent high-temperature resistance. In contrast, ordinary cement mainly contains silicates and its performance is relatively conventional.

Different compressive strength

Refractory cements tend to perform better, especially at high temperatures, where their strength remains more stable.

Different shrinkage rates

Refractory cement is also far superior to ordinary cement in terms of shrinkage at high temperatures, with less shrinkage helping to maintain structural stability.

Different application scenarios

Refractory cement is usually used in places that are exposed to high temperatures for a long time and in places with certain corrosiveness, 炉など, fireplaces, industrial kilns, high-temperature chimneys, 等. Due to its superior high-temperature resistance and fire resistance, it can effectively protect the structure from high-temperature damage.
Ordinary cement is more commonly used in the construction field, such as houses, bridges, roads, concrete structures, 等, for general construction and infrastructure construction. Ordinary cement has high bond strength and durability and is suitable for structures that bear static and dynamic loads.
