2. INTRODUCTION
• AAC was invented in mid-1923 in Sweden.
• It is also known as Autoclaved CellularConcrete
(ACC) or Autoclaved Lightweight Concrete
(ALC).
• Aeration process, imparts it a cellular light-
weightstructure.
• AAC products are precast in various sizes and
provide structure, insulation,and fire and mold
resistance

3. • Aerocon bricks are three sizes: Infill, Jumbo,
and Thermal blocks
TYPES OF AEROCON BRICKS

4.  Infill blocks
The size of the InfillAerocon brick is
600X600mm and the thickness varies
in theranges of 75-200mm.
caneasily replace 60% of the concrete in
roof slabs ,
significantamounts of concrete, steel, labor,
water, plaster etc.

5. Jumbo blocks
•Jumbo blocks are typically in
the size of 600X300 mm, and
thickness ranges from 75to200
mm.

6. Thermal blocks
•These blocks are also called as
Aerocool thermal blocks whose
size and thickness is 300X200 mm
and 50 mm respectively.

7. Advantages
• Easy to install. They are easy to install and
can complete the construction procedure
in a shorter span.
• Aerocon blocks acts as better substitutes
for bricks and concrete blocks for Partition
Walls.
• Strength and durability

8. Disadvantages
•Not many contractors and people are
familiar with the product.
•The initial cost for the manufacturing
plant is high compared to bricks.

9. DESIGN CONSIDERATIONS
General considerations
AAC masonry components (block units) can
be used to build load bearing or non load
bearing walls.
• O-block units used to build pilasters.
• U-block units used to build bond beams
and lintels.

10. Installation Guide
• Check foundation.
• Receiving and distribution of
AAC wall units.

11. Installation requirements
• Tools
• Equipment
• Other materials
• Installing O-block for pilasters in first
course

12. Laying the first course (levelling
course)
• Lay the first course over a semi-dry
cement mortar levelling bed- ½" to
2" thick.
• Corner blocks are laid first and the
first course should be completed
before second course installation.

13. Cutting blocks
• A hand saw or band saw to cut the blocks to
specific lengths
Placing control joints in first course
• These are vertical joints taken through the full
wall thickness, and from bottom to top.
• 3/8" to ½" thick.

14. Raw Material Preparation and Storage
• • The first step of AAC production is
grinding of silica rich material (sand, fly
ash, etc) in ball mills.
• • There are two methods for mixed
milling.
• • One is dry mixing to produce binding
material, and the other method is wet
mixing.

15. .
• Other supplementary
and chemicals are
also have to be
prepared. Raw
material storage
assures the
continuous
production and
material stability
•It is the basic process that assures the smooth
production and production quality

16. Dosing and mixing
• • Maintaining ratio of all ingredients as per the selected
recipe is critical to ensure consistent quality of
production.
• • Fly ash/sand slurry is pumped into a separate container.
• • 0nce the desired weight is poured in, pumping is
stopped.
• • Dosing unit releases this mixture as per set quantities
into molds for foaming.
• • Dosing and mixing process is carried out continuously
because if there is a long

17. Demoulding and Cutting:-
• > Cutting operation is achieved by
moving green cake through
horizontal cutting machine.
• > Horizontal or Vertical cuttings are
made through cake using
stationary steel wires.
• > These wires can be adjusted
offline to get desired height of AAC
blocks or panels.

18. ITS IMPORTANCEIN NEXTGENERATION
CONSTRUCTION
Use of waste Product:
• Fly Ash is usually a by-product of thermal power plants and is an important
raw material in the manufacture of AAC Blocks.
Water Conservation:
• AAC blocks don't need curing, as water used in other ordinary Clay Bricks
Durability: -
• AAC has a very porous structure filled by Air Bubbles which arrests water
absorption into the AAC material is minimum. So, It leads to Low
maintenance and increased durability.
Recycle / Reuse :-
• Waste from the cutting process is recycled back with raw materials and
used again.
• "AAC blocks can be reused into base preparation of roads

19. COST ANALYSIS
• > Cost of building materials vary from
region to region.
• > For Instance, one cubic meter comprises
of 600 bricks, which costs around Rs.3000-
4000/- cubic meter.
• > However, AAC blocks are available at the
range of Rs.2800-4000/- per m3

20. CONCLUSION
• • As a construction system, AAC provide
significant environment and other benefits
for the building owner.
• • The short and long term effect of using
AAC compared to many other materials
results in lower energy consumption,
reduced operating costs, greater safety
and comfort, and a healthier and more
trouble - free building.
