Advantages of CLC

CLC Blocks cut to custom sizes on site.

  • CLC Bricks have excellent compressive strength in excess of regular clay bricks / solid blocks, guarantees min. Compressive strength of 3N/mm2.
  • Bending strength is 15 to 20% of compressive strength.
  • CLC Bricks density is 800kg/m2 which reduces dead load on structures.
  • Huge saving in foundation and structure savings upto 30% on beam costs.
  • Good earth quake resistance properties.
  • Easy handling. Lightweight CLC is easy to transport and stock.
  • Faster construction. CLC blocks are easily cut to custom size requirements on size using basic power-tools.
  • Huge saving of labour. Faster construction directly relates to reduction in labour requirement.
  • CLC Bricks offer highest thermal insulation making cool summers and warm winters.
  • Reduced Air conditioning expenses. Air-conditioning energy requirements can be 5 times lower than conventional structures.
  • CLC Bricks are fire resistant.
  • Non toxic fumes in case of fire.
  • Excellent acoustic barrier. More peace of living, No disturbance from your neighbour'[s home theatre.
  • Highly accurate and smooth walls reduction in plastering.
  • Opt for any finish on walls – external plastering, tiling, cladding, internal tiling, dry lining, spray plaster or anything of your choice.

Advantages in detail:

  • Savings in Raw Material: The tremendous savings described when using CLC are manifold, continuing with substantial savings in raw material (no gravel required), in dead load of high-rise reducing by almost half. Considering that a substantial amount of steel is necessary only to carry the weight of the structure, steel requirement might reduce by hundreds of ton in high rise.
  • Considerably Lower Weight: Weight reduction is obvious in transport, where almost double of volume of building material can be produced, it has an impact on craning, where either larger panels can be taken, or the full capacity in span. Alternatively less re-location of the crane is necessary.
  • Thermal Insulation: Thermal Insulation increasingly turns to be the most important issue in the planning and construction of buildings. There are many costly ways of insulation on sandwich structure of a wall, adding the one or another rigid insulation material, with a satisfactory result by computation but not always a sound solution in safety, health or environment. The best solution is, to incorporate thermal insulation in the mix of a concrete, such offered in air-cured CLC.
  • Fire Protection: The air-embedded in the CLC is also instrumental for the high fire-rating. In 1200 kg/m³ density a 13-14 cm thick wall has a fire endurance of 5 hours. The same delay occurs with a 400 kg/m³ layer of CLC in only 10 cm thickness. CLC is otherwise non-combustible.
  • Sound Insulation: Over the efforts to keep on increasing the thermal capacity of building members, other aspects have been neglected, such as sound insulation. Sound is experienced as air-borne or foot-fall sound (impact ). Air-borne it is a rule of density and therefore CLC offers superior protection than very light concrete (ACC). In impact sound it is superior to conventional concrete. Hitting a wall with a hammer, will let you feel the full force on the other side, whilst the air embedded in CLC will not allow the blow to pass through. At the most it will suffer a small dent and thereby prevent any greater damage.
  • Insulated Flooring: As the impact force will not transmit, slabs produced of CLC or topped with a layer of CLC floor screen will prevent any sound being noticed in the room below. Walls of CLC will also serve as sound retaining walls on roads or railway tracks therefore, absorbing the sound and preventing it from bouncing to the other side.
  • Customisable Physical Properties: Adding fibers to CLC is a further important benefit, increasing bending stress substantially and most of it impact strength. The three dimensional acting fiber (e.g. polypropylene) will further reduce shrinkage, therefore reducing water absorption and increasing strength (up to 25 %. This is appreciated most when producing slender building components.
  • Economical Production: Using only flyash, cement, water and foam, the cost for one m³ of CLC in most cases is less even than for the equivalent volume of conventional concrete. Adding all the described highly appreciated benefits (comprising CLC) to regular concrete, if at all possible, the cost for such regular concrete would probably double but still not reach the overall quality of CLC.
