CAC (Calcium Aluminate Cement)

• CAC (Calcium Aluminate Cement) is a type of hydraulic binder manufactured by fusing limestone and bauxite in a kiln. CAC cement sets quickly, and its high early strength is beneficial in precast concrete production, where rapid demolding and handling are required. CAC cement is also used in refractory castable, which is used to line high-temperature furnaces, kilns, and boilers.

  Some of how CAC is useful in construction (pre-bagged dry mix systems), mining, water treatment, sewer rehabilitation, refractory, and other applications are:

  • Rapid setting: CAC has a high early strength and can set and harden quickly. This makes it useful in applications where a fast turnaround time is required.
  • High strength: CAC has excellent mechanical strength and can be used in various construction and refractory applications requiring high strength.
  • Acid resistance: CAC is highly resistant to acidic environments and can be used in applications where exposure to acids is expected, such as in water treatment plants.
  • Reduced drying shrinkage: CAC has a low shrinkage rate compared to Portland cement, making it suitable for applications where cracking due to shrinkage is a concern.
  • Sewer rehabilitation: CAC is commonly used in rehabilitating sewer pipes due to its ability to withstand the harsh chemical environment found in sewer systems.
  • Refractory: CAC is commonly used in refractory applications due to its high melting point, making it ideal for use in the linings of furnaces and kilns.
  • Pre-bagged dry mix systems: CAC is used in pre-bagged dry mix systems to provide a rapid setting and high strength to the final product.
  • Mining: CAC is used in mining applications as a binder in manufacturing explosives.
  • Water treatment: CAC is used in water treatment applications because it neutralizes acidic water.
