TRANSCRIPT
AUTOCLAVED AERATED CONCRETE BLOCKS
Presentation by:R.MEHAR BABU(04-04-0004)
INTRODUCTION:
• Clay bricks, the mainstay of building construction, are steadily giving way to a new, vastly improved building Blocks concept in India.
• As the fly ash is the material which is available in abundance, the idea of introducing fly ash into Concrete blocks along with some other binding materials has added strength and reduced weight..
• The addition of flyash has reduced the cost of the block.
WHAT IS AUTOCLAVED ?• The term Autoclaved means high pressure steam
cured for added strength and dimensional stability to blocks
• Aerocon blocks are an excellent substitute • Aerocon Blocks are eco-friendly and are ideal for
modern day buildings, assuring quality construction and comfortable living.
• Aerocon Blocks are ideal material for all types of partitions due to their light weight, fire resistance and superior acoustic properties.
• mixture of cement, fly ash, lime and water involving an aeration process that imparts its unique cellular structure.
TYPES OF AAC BLOCKS
• Aerocon HQ Blocks
• Aerocon jumbo blocks
• Aerocon infill blocks
AEROCON HQ BLOCKS
• Aerocon HQ Blocks are made with a mixture of cement, fly ash, and special additives along with water involving areation process that imparts its unique cellular structure.
PROPERTIES OF AEROCON HQ BLOCKS
1. Light Weight: 1/3rd the density of clay bricks. Hence Economic design and savings in cement and steel.
2. High Thermal Insulation: Thermal performance 5 times better than clay brick & 10 times better than RCC.
3. Good Sound Insulation 4. FireResistance: withstood standard fire test for 4
hours
ADVANTAGES
• Perfect Finish
• Big Savings
• FlexibleWallThickness-Bydesign
• EaseofWorkability
Relevant I.S. code • IS 2185 (Part III) - 1984 : Specification for AAC• IS 6041 - 1985 (Reaffirmed 1990): Code of
practice for construction of AAC block masonry.
• IS 6441 - 1972 (Part I to Part V): Methods of testing for AAC Products
AEROCON JUMBO BLOCKS
• AJB blocks are prepared same as HQ BLOCKS.
• Aerocon Jumbo Blocks are designed to get the benefits of their unique size in terms of mortar consumption, speed of construction, thermal insulation and ease of handling.
• Some practical tests abroad have shown that productivity can be increased by up to 200% with jumbo blocks when compared with conventional block laying.
Applications of jumbo blocks
• Suitable for both load-bearing and non load-bearing walls.
• Ideal for multi-storeyed buildings.
• Most suitable where thermal comforts at home and savings in air-conditioning cost are desired.
• Suitable for all fire-rated applications.
Outstanding Advantages of jumbo blocks :
• Savings in mortar
• Faster construction.
• Enhanced thermal and sound performancedue to less joints.
• Economic design -Savings in cement and steel.
• Easy handling even jumbo size due to lower density
• Light-weight -1/3rd the density of clay bricks
Relevant I.S. Codes
• I.S. 2185 (part III) -1984 : Specification for AAC.
• I.S. 6041-1985 Reaffirmed 1990 : Code of practice for construction of AAC
Block masonry.
• I.S. 6441- 1 972 (part I to part V) : Methods of testing for AAC products
AEROCON INFILL BLOCKS:
• Aerocon Infill Block is mixture of cement, fly ash, lime, aluminum powder and water involving an aeration process that imparts its unique cellular structure.
Applications:
• Any Roof with large column free space constructions.
• Commercial and multistoried buildings.
• Extension of unplanned floors.
• Fire rated buildings.
• Air-conditioned buildings
• MOST SUITABLE FOR LONG SPAN ROOFS
