What is an aerated concrete block?
Aerated blocks are a type of innovative concrete blocks that contain more than 80 percent air. They are also called autoclaved aerated concrete (AAC). Aerated concrete is a group of materials you would describe as lightweight concrete.
What are the disadvantages of AAC blocks for home construction?
Some of the Main Disadvantages of AAC Blocks are given below:-
- AAC Block is Non load Bearing material, it can be used only in wall partitions.
- AAC block is brittle in nature that means It can break easily.
- Their water absorption is very high.
What is the difference between AAC blocks and concrete blocks?
The solid concrete blocks are used as an alternative of clay bricks but concrete blocks are heavy in weight hence buildings becomes heavy. The cost of concrete block masonry is also high hence AAC blocks are used in the construction of the wall.
How do I check quality of AAC blocks?
AAC Blocks have a compressive strength of an average (3-4.5) N/mm³….Specification :-
| Size | mm | 600 x 200 x (75 to 300), |
|---|---|---|
| Compressive Strength | N/mm 2 | 3 – 4.5 (IS 2185 part 3) |
| Normal Dry Density | Kg / m 3 | 550 – 650 |
| Size Tolerance | mm | ± 1.5 |
| Fire Resistance | Hrs. | 2 to 6 (Depending on Thickness) |
Are aerated blocks strong?
Autoclaved aerated concrete blocks are very strong and they far outlast that of their ordinary counterparts. The blocks consist of materials that are not biodegradable and repel mold. Because of their great strength, AAC blocks are more stable as well.
Can aerated blocks be used externally?
Yes they can be used externally.
Can I use aerated blocks outside?
Are aerated blocks load-bearing?
Aerated blocks can be used for lightweight partitions and loadbearing internal walls. They have been available for about 40 years or so and have replaced earlier lightweight blocks made from a variety of lightweight aggregates.
Are Thermalite blocks the same as aerated blocks?
Thermalite Hi-Strength Smooth Face Hanson’s Thermalite blocks are lightweight, meaning they can be laid more quickly. The aerated concrete blocks contain pockets of trapped air providing good compressive strength, high levels of thermal insulation and moisture resistance.
Are aerated blocks load bearing?
Can you use aerated blocks for retaining wall?
Do aerated blocks absorb water?
Now, let’s look through 6 disadvantages of aerated concrete: due to high water absorption, finishes required to breath to prevent environmental impact (weathering) on the aerated concrete, i.e. Cover autoclave aerated concrete with plaster, decorative facades, etc.
