Calcium aluminate cement (CAC) is a type of hydraulic refractory cement. It solidifies within 6 hours at 25-35 degrees Celsius. Additionally, its flexural strength and compressive strength are enhanced within 24 hours. Compared to common Portland cement, this cement has higher early strength and faster setting time. Kerui exported this product to 50+ countries. And we received good reviews.
