What is CLCCELLULAR LIGHTWEIGHT CONCRETE (CLC), IS A VERSION OF LIGHTWEIGHT CONCRETE THAT IS PRODUCED LIKE NORMAL
CONCRETE UNDER AMBIENT CONDITIONS. IT IS PRODUCED BY INITIALLY MAKING A SLURRY OF CEMENT + FLY ASH (OPTIONAL) +
SAND + WATER, WHICH IS FURTHER MIXED WITH THE ADDITION OF PRE-FORMED STABLE FOAM IN AN UNIQUE FOAMED
CONCRETE MIXER. THE MIXTURE IS EITHER POURED OR PUMPED INTO ASSEMBLED MOULDS OF BRICKS OR FORM-WORK OF
REINFORCED STRUCTURAL ELEMENTS OR POURED ONTO FLAT ROOFS OR VOIDS FOR THERMAL INSULATION OR FILLING. The
foam imparts free flowing characteristics to this slurry due to ball bearing effect of foam bubbles enabling it to easily flow
into all corners and compact by itself in the moulds/forms without requiring any kind of vibration or compaction.
Cellular Light Weight Concrete (CLC) technology has been used in over 45 countries of the world over the past 30 years to
construct Over a hundred thousand houses, apartments, schools, hospitals, industrial, commercial buildings etc.
The introduction in India of a modified version using over 40% fly ash has made it an even more eco-friendly and cost
effective version of CLC. The new product is set to revolutionize the manner in which buildings are constructed. In the
process, the product brings quality housing closer to the masses at a faster and at a lower cost.
Advantages of CLCAdvantages of CLC Bricks
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.
Faster construction.
Huge saving of labour.
CLC Bricks offer highest thermal insulation making cool summers and warm winters.
Reduced Air conditioning expenses.
CLC Bricks are fire resistant.
Non toxic fumes in case of fire.
Excellent acoustic barrier. More peace of living, No disturbance from your neighbours 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.
CLC Flooring
Brickwell CLC is used for roofing and flooring applications
extensively.
A low density mix is chosen and the resulting air content gives the material excellent thermal insulation properties.
The low density also has the advantage that it does not significantly add to the overall weight of the roof.
Foamed concrete has two benefits when it is used for roofing. The first benefit is that it provides a high degree of
thermal insulation. The second benefit is that it can be used to lay a flat roof to falls, i.e. to provide a slope for
drainage. Foamed concrete is also much lighter than slopes made from mortar screeds. This means that a roof with
a slope made of foamed concrete imposes a lower loading on the structure of the building.
CLC can be produced and poured for floors and roofs on-site. In roofs it can be used because of very good
insulation properties and it is comparitively lightweight.
For floors CLC offers faster installation and a less expensive option because of the flowing and self-leveling
properties.
CLC BricksCellular Lightweight Concrete (CLC) bricks are environment friendly and manufactured from common natural raw material.
The energy consumed in the production process is only a fraction compared to the production of other materials and emits
no pollutants and creates no toxic products or by products. The CLC bricks that we offer provides thermal and sound
insulations and also fire protection eliminating need for many layers of plastering and do not emit any toxic gas when
exposed to fire. These bricks are highly strong and of customized shape thus requiring less amount of cement and plastering
and giving an even shape to the construction.
Brickwell’s manufacturing unit located at multiple cities, supplies CLC
Bricks to residential, commercial and industrial real-estate developent projects across India.
Brickwell’s wholly owned manufacturing unit can produce CLC Bricks as per standard industrial sizes or tailored for your
specific requirements. 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.

The properties of cellular concrete obtained by using the specific foaming agent Isocem S/L, however, are influenced by the
foam/cement ratio, rather than by the properties of the foam itself, and this ratio determines the final heat and sound
insulation properties ot cellular concrete.
ISOCEM S/L is an innovative foaming agent, made up of natural surfactants mixed to vegetable raw materials: it is highly
effective and can also be used as an air-entraining additive for cement mixes containing light aggregates (EPS, vermiculite
etc.).
Physical Properties:
The most significant physical property of cellular concrete is its density. It is determined by the quantity of air in a cubic
meter of material, that is by the air/cement ratio. The most frequently used densities are:300 kg/m3400 kg/m3500 kg/m3600
kg/m3
These densities correspond to different values of thermal insulation and mechanical resistance, which approximately amount
to the values in the following tables:
D 300 kg/m3 = 0.062 kal/m/h/C°
D 400 kg/m3 = 0.08 kal/m/h/C°
D 500 kg/m3 = 0.09 kal/m/h/C°
D 600 kg/m3 = 0.12 kal/m/h/C°
Doses: 2.5-3% (percentage of foaming agent for the production of cellular concrete).Applications: layers and/or sloping
terraces.
Storage: 1000 kg tanks or 200 kg drums.
CLC Blocks are competitive with bricks in pricing and offer significant savings for finished structures.
Savings in construction cost can be as much as 18% when using CLC Blocks, as compared to brick, after taking
into account the resulting savings in gravel, cement, steel, labor, structure, foundation etc.
