➤ The significant detriments of autoclaved circulated air through cement are recorded underneath.
➤ The generation cost per unit for AAC is higher than other standard cement.
➤ The quantity of the maker is constrained. In this way, the cost will radically increment in places a long way from the maker and need to travel a long separation.
➤ It isn't as solid as traditional cement.
➤ Autoclaved Aerated Concrete is a Lightweight, Load-bearing, High-ensuring, Durable structure thing, which is made to a wide extent of sizes and characteristics.
➤ AAC Blocks is lightweight and appear differently in relation to the red squares AAC squares are on numerous occasions lighter.
⧪ Quality Checklist of AAC Block on construction site:-
STACKING:-
➤ Stacking ought to be done uniquely on even and leveled ground surface over the 100 - 200 mm for Ground Surface
JOINTING:-
➤ Keep it Limited to 10 to 12 mm with ordinary concrete mortar and 3 to 4 mm with instant jointing mortar
Adapting:-
➤ Adapting Beam to 2 number of 8 width fortification bar after 1.2 to 1.4 m range from the beginning level
MOTAR FOR MASONRY:-
➤ Instant jointing synthetic with 3 to 4 mm thickness or with traditional bond mortar (1:6 )
Lintel:-
➤ Least 150 mm support for lintel at the two sides. Lintels ought to be put on a mortar bed
WETTING OF BLOCK:–
➤ Prior to the use of mortar, dunk hinder in water and lift quickly or apply water with brush
Relieving OF MASONRY:-
➤ Relieving required uniquely for bond mortar joint and not required for instant mortar jointing
CUTTING OF BLOCK : -
➤ Use an instrument like a hacksaw or rotating shaper or hand wood saw
Mortar:-
➤ Least External mortar thickness 12 to 15 mm
Stature:-
➤ Watch that AAC shut isn't done in excess of 1200 mm ina day
Resilience:-
➤ Check verticality and Alignment of the AAC BLOCK. Deviation will not be in excess of 10 mm in Alignment and 5 mm in verticality for 3m tallness.
⧪ Favorable position of AAC Block portrays as following:-
1. The AAC Block helps in fast construction work, in this way decreasing time and construction costs. In AAC Bricks it is anything but difficult to utilize standard instruments for cutting the dividers for electrical work, including boring of openings
2. AAC Blocks have a compressive quality of a normal (3-4.5) N/mm³. This is better than most sorts of lightweight squares. Also, it is 25 percent more grounded than different results of a similar thickness.
3. The AAC Blocks are impervious to fire between a specific farthest point of time. It is from a 2 hours least time to 6 hours' most extreme time limit.
4. The AAC Blocks are impervious to bugs and bugs.
5. AAC Blocks are impervious to seismic tremors. The common property it is produced using is light in weight. This, thusly, expands the soundness in the structure structures.
6. AAC Blocks are profoundly financially savvy in nature. Therefore, offering cost-sparing and less interest in construction work.
7. The AAC Blocks are Non-harmful in nature. They can't be harmed from smoke from contamination and smoke of the smokestack in industrial facilities.
8. AAC Blocks are lightweight. It is the greatest component, which is useful in transport and during construction fill in also.
9. Warm protection the AAC Blocks have protected characteristics. The warm conductivity level of the AAC Bricks keeps the room temperature warm during winter. In summer, it is cool and decent. By the day's end, it offers colossal investment funds on cooling load, which means less power bills.
10. ACC Blocks are soundproof in nature. This is because of their permeable nature, which assimilates sounds up to certain decibel levels.
