high aluminum cement
Quick Summary
High-alumina cement is a type of hydraulic cement characterized by a higher alumina content compared to Portland cement. This composition allows it to develop strength more rapidly and exhibit greater resistance to heat and chemicals.1
It is produced by fusing bauxite and limestone at high temperatures, typically between 1,500 to 1,600 °C, or through sintering at around 1,250 °C. The primary cementing compound in high-alumina cement is calcium aluminate. This cement gains a significant portion of its ultimate strength within 24 hours and is valued for its durability against chemical attack. A white variant, with minimal iron oxide and silica, possesses exceptional refractory properties, making it suitable for lining furnaces.2
