LITEBUILT Cellular Concrete Technical Details

LITEBUILT cellular concrete stacks up! 

Our cellular concrete is a patented technology and we continue to see the superior results of our product after every new application. We stand by the technical benefits that LITEBUILT™ products provide:

Fire Resistance

LITEBUILT cellular concrete is extremely fire resistant

  • A 150 mm thick LITEBUILT™ concrete wall was exposed to a furnace up to 1200°C and maintained fire resistance for 5 hours (Fig. 1)
  • Intense heat does not cause the cellular concrete to spall or explode, or give off toxic gases, fumes or smoke
  • Reinforced steel remains cool and protects for longer time than standard concrete

Acoustical Insulation

LITEBUILT cellular concrete has a high sound absorption capacity

  • Low frequency noise is greatly absorbed, making it an ideal insulating layer on structural slabs to restrict noise transmission from floor-to-floor in multi-level residential or office buildings
  • Cost of additional materials to reach required sound insulation is greatly reduced when compared to other methods of construction

Thermal Insulation  

LITEBUILT cellular concrete provides outstanding thermal insulation

  • Very low transmission of heat reducing the requirement for additional insulation in floors and walls
  • Energy is saved by cutting both heating and air conditioning requirements, giving greater comfort in a wide range of temperatures
  • Condensation from atmospheric humidity, which arises from changes in the ambient temperature, is reduced

Structural Integrity

LITEBUILT cellular concrete meets or exceeds conventional concrete structural integrity

Compressive Strength

  • The controlled LITEBUILT™ cellular concrete mixes allow us to ensure the quality and consistency of the end product
  • Compressive strength tests are continuously conducted through our Quality Control Program
  • Compressive strength is optimal at a 28 day cure and continues to increase over time
  • Has a faster “rate of use” than conventional weight concrete so it can be built on top of/in conjunction with much faster than traditional concrete

Tensile Strength

  • Cellular concrete can be as high as 0.25 of its compressive strength with a strain of around 0.1% at the time mold release so it is not prone to cracking like traditional concrete

Shear Strength

  • The shear strength of our product varies between 6% and 10% of the compressive strength so reinforcement is seldom required in flooring and roofing units

Expansion

  • The coefficient of linear expansion for cellular concrete is of the same order as that of conventional concrete (i.e. 0.000009 per degree centigrade)
  • This factor becomes important when using cellular concrete on large areas of roof slabs which are exposed to heat and cold

Shrinkage

  • Cellular concrete, like all cement, shrinks during the curing stage
  • The greater extent of shrinkage occurs during the first 28 days, after which time it is negligible
  • If the conditions of cellular concrete are well controlled during the first 28 days, shrinkage can be kept under 0.1%
  • This specifically applies to our LITEBLOK™ building product under our QC controlled program to ensure there are no changes from structural shrinkage once the blocks are in use
  • All other applications have a much faster “use” rate than traditional concrete
