High alumina cement (HAC) is a specialized binder widely used in high-temperature industrial applications, providing excellent refractoriness, chemical stability, and fast strength development. Unlike ordinary Portland cement, high alumina cement is engineered to withstand extreme thermal and chemical conditions, making it a preferred material in steel, cement, glass, petrochemical, and energy industries.
At Highland Refractory, we offer high-quality high alumina cement designed for durable performance in refractory castables, monolithic materials, and pre-cast industrial components. Our products are carefully manufactured to deliver consistent high Al₂O₃ content, rapid strength development, and long-term operational stability, ensuring our customers’ industrial processes run safely and efficiently.
High alumina cement is produced by calcining high-purity bauxite and limestone at high temperatures and grinding the resulting clinker into a fine powder. Its primary component is Al₂O₃, typically ranging from 50% to 85%, depending on the grade. The high alumina content provides:
Superior refractoriness, allowing continuous operation at temperatures exceeding 1750°C
Rapid strength gain, shortening curing and drying periods
Resistance to chemical attack from slags, acids, and molten metals
Compatibility with a variety of refractory aggregates, including corundum and high alumina bricks
Highland Refractory’s high alumina cement is specifically formulated to meet the rigorous demands of industrial applications worldwide, supporting long-term furnace performance and safety.
High alumina cement is extensively used in industries where high-temperature performance, chemical stability, and mechanical strength are critical. Below are the key industrial applications.
High alumina cement plays a vital role in steel furnace linings, providing strong bonding for refractory castables used in:
Electric Arc Furnace (EAF) linings
Ladle and tundish refractory castables
Steel transfer channel linings
