Technical Specifications


Walls of CLC have excellent sound insulation

CLC Bricks are available in 3 grade strengths:

  • Grade A: These are used as load bearing units & have a brick density in the range of 1,200 kg/Cum – 1,800 kg/Cum
  • Grade B: These are used as non-Load bearing units & have a brick density in the range of 700 – 1,000 kg/Cum.
  • Grade C: These are used for providing thermal insulation & have a brick density in the range of 400 – 600 kg/Cum.

Recommended usage of CLC based on density:

  • Density 300-600 kg/m³: This density is primarily applied for thermal insulation or fire protection. It uses only cement (or little flyash), water and foam and can easily be pumped. Foam generators allow the production of stiff foam for slopes to be applied on roof-tops.
  • Density 700-800 kg/m³: Is also used for void-filling, such as an landscaping (above underground construction), to fill voids behind archways and refurbishing of damaged sewerage systems. It is also been used to produce building blocks.
  • Density 900-1100 kg/m³: Serves to foremostly produce blocks and other non-load bearing building elements such as balcony railings, partitions, parapets and fence walls etc.
  • Density 1200-1400 kg/m³: Are the most commenly densities for prefab and cast in situ walls, load-bearing and non-load-bearing. It is also successfully used for floorscreeds (sound and insulation plus weight reduction).
  • Density 1600-1800 kg/m³: would be recommended for slabs and other load-bearing building elements where higher strength is obligatory.
