High Alumina Cement (HAC) is a special type of cement made by fusing or sintering a mixture of bauxite (aluminium ore) and limestone. Unlike ordinary Portland cement, it has a high content of alumina (typically 35–80%), which gives it unique properties.

HAC is darker in color (usually grey to black), rapid hardening — gains strength much faster than normal cement and is excellent resistant to high temperatures, chemicals, and sulfates.


Application

---

• Refractory linings (furnaces, kilns)

• Sewer and marine structures

• Rapid concrete repairs

• Precast in harsh environments

• Chemical and industrial plants

• Cold weather concreting

Benefits

---

• Rapid strength gain – early high strength within 24 hours

• Excellent heat resistance – ideal for high-temperature environments

• Chemical resistance – performs well in acidic or sulfate-rich conditions

• Minimal shrinkage – maintains dimensional stability

• Low permeability – enhances durability and reduces corrosion risk

• Improved resistance to abrasion – suitable for heavy-duty surfaces

• Performs well in cold climates – suitable for winter concreting

Packaging

---

• 25 kg/bag
