Foam concrete is also known as cellular light weight concrete. Do not confuse with other names like lightweight concrete, aircrete, foamcrete, low density concrete.
Foam concrete
consists of fly ash, sand and water. Sometimes cement is used instead of fly
ash. However, the slurry is mixed with aerated foam in a concrete mixing plant.
These aerated foams produce air bubbles.
Foam concrete has low density ranging about 400 kg / ㎥ to 1620 kg / ㎥
Uses of foam concrete
1. To make
aerated concrete blocks.
2. To create a
cavity wall for the purpose of insulation.
3. Protecting
the construction of interior space from external heat.
4. Building an
auditorium and multiplex wall where the sound is very high.
Advantages of foam concrete
1. It is thermally
insulated.
2 It is sound insulated
3. It resists
fire.
4. It is very
environmentally friendly.
5. Very low cost
due to the use of fly ash.
6. Self-leveling.
7. Self-consolidating.
8. Easy to
transport.
Disadvantages of foam concrete
1. Very low
strength.
2. Expensive
equipment needed.
3. High
shrinkage.
4. High mixing
time.
Differences between:
Whole Circle Bearing vs Quadrantal Bearing
Lintel level vs Sill level vs Plinth level
Construction Joint vsExpansion Joint
Site Engineer vs SiteSupervisor
