Why use "Ghacem Super SUPER RAPID Portland limestone Cement"    
  (Class 32.5R)?

  • Super Rapid results in high early strength development. This enables target customers to improve on their work rate, enhance repetitive use of other construction materials such as moulds and formwork. Example, Block Makers can strike their moulds more quickly and thus sell in a shorter period after casting.
  • Water-retention of cement is enhanced in Super Rapid. Cement requires water for its chemical reaction to enable it develop strength. This characteristic (water-retention) of the cement directly effects its strength development
  • Good workability is better achieved with the use of Super Rapid. Lean mixes of cement and sand are harsh and unworkable, nevertheless, Super Rapid is designed on the principle that part of the cement is replaced by an equal volume of limestone so that the binder paste still fills the voids in th e sand. In this way good working qualities can be secured.
  • Shrinkage of concrete is reduced in Super Rapid. The higher fineness of the cement reduces the tendency for «bleeding», which also reduces the shrinkage of the concrete.
  • Bonding properties of Super Rapid are pronounced. The presence of fine particles of limestone component in the cement enhances the bonding properties of the cement.
  • Plasticity of cement mortar is more pronounced with Super Rapid. The bonding properties, workability and other properties of the cement enable concrete made with Super Rapid to be easily moulded into required shapes to attain desired aesthetics.
  • Super Rapid uses Ghanaian raw material, in the form of limestone, for its production. Continuous usage of Super Rapid Cement will guarantee business opportunities, job creation, and increased government revenue.
  • Again Super Rapid is environmental friendly since its composition of higher limestone content reduces carbon dioxide emission into the air.
