Lightweight concrete can be prepared either by injecting air in

its composition or can be achieved by omitting the finer sizes

of the aggregate or even replacing them by a hollow, cellular

or porous aggregate.

i ) No-fines concrete

ii) Lightweight aggregate concrete

iii) Aerated/Foamed concrete

Produced with the help of a Foam Generator by using a

foaming agent.

It contains isolated air bubbles, which creates million of

unconnected tiny voids or cells in the mix.

Wide range of controlled densities from 400 kg/m3 to 1,800kg/m3.

The density recommended is 1kg/m3 for blocks and 1.2 kg/

m3 for prefab elements and walls cast in-situ.

It is being used long timeago as a conventional,

simple and economical

solution for buildings

roofing. The practical experience

shows a number of

disadvantages related to

using the conventional

Concrete tiles for roofing.


14/20

It is one of the newlyproduced materials used

instead of the Concrete tiles.

The most ideal solution for

roofing in Iraq and theMiddle East where

temperature varies

extremely.

The area to which highperformance cellular concrete

can be applied in the

development of light weight

binary density insulatingcontrol panel system

Product consideration of future

generation in new building


16/20

Optimum thermal insulation

Substantial weight reduction

Highly increased fire rating

Maximum sound absorption

Fast progress in construction

Saving in raw material

Savings in steel reinforcement in high rise

Savings in transportation

Savings in craning


17/20

Very sensitive with water content in the mixtures

Difficult to place and finish because of the porosity and

angularity of the aggregate.

In some mixes the cement mortar may separate the aggregate

and float towards the surface

Mixing time is longer than conventional concrete to assure

proper mixing


18/20

As reinforced load-bearing in-situ walls and roofs in LowRise Buildings.

Even block-work can also be used for load-bearing low rise

constructions.

Non load-bearing internal or external walls in High Rise

Buildings.

Thermal Insulation of building roofs and walls & roofs of cold

storage.
