Frequently Ask Question

AAC block full form

5 Star AAC Blocks made of AAC are referred to as autoclaved aerated concrete block and are among the most eco-friendly and light construction materials.

What exactly are AAC blocks?

AAC blocks are precast, foam concrete environmentally sustainable construction material made of quartz sand aggregates as well as calcined Gypsum, portland cement, lime aluminum powder and water. Following mixing, moulding and curing the concrete is autoclaved using pressure and heat, and therefore acquires its unique properties. AAC bricks are highly in great demand because of their strength, load-bearing , and thermal insulation characteristics.

AAC block is utilized to construct constructions both for exterior and interior. Blocks can be coated with stucco or siding materials such as vinyl siding or veneer brick.

AAC block cost: AAC blocks sizes and prices

Autoclaved concrete manufacturers create AAC blocks in various sizes and strength. The AAC block cost is for rectangle AAC bricks that have a size (length * height + weight) that is 600mm by 200mm x250mm could range from Rs 3,500 to Rs 4,500 for a cubic meter. The AAC blocks' sizes and prices vary, based what the maker of the block is.

AAC blocks arrangement

The material is offered in AAC panels and blocks. The blocks are laid out in stacks in the exact fashion as traditional mortar. However, the mortar is thin-layered is used, and the panels are arranged vertically. For structural purposes, they can be reinforced, grouted cells and beams can be included within the wall's wall section. Blocks can be laid out by hand. However, the positioning of AAC panels requires the assistance of equipment, such as cranes due to their huge size.

AAC blocks shapes

Lintel blocks, sometimes called U-shaped bond beams are available in the thickness of 8, 10 and 12 inches.

Tongue and groove AAC slabs or blocks are available in huge dimensions. They can be connected to other units without using mortar along those vertical edges.

Cored blocks are utilized for the construction of vertical grout cells.

AAC blocks' disadvantages: Why why is AAC block not being used in foundation?

While AAC blocks are commonly used in masonry units in high-rise RCC (reinforced cement concrete) frames however, they can be costly when they are used in smaller load-bearing structures. When you're using AAC blocks, this could become one of the drawbacks. With the price of AAC block prices, purchasing only a few blocks for structures of this kind can cost more as when compared with ordering bulk in large quantities for larger projects. But, it is light and therefore can be used to reduce dead load and the use for structural steel is decreased in RCC frame structures. This means it will reduce construction costs in the case of high-rise constructions.

Additionally, the column foundations of RCC frames are built to bear the load of a structure. In these types of constructions, RCC foundations are arranged upon which RCC columns are elevated. Plainth beams are set on the plinth and block masonry from AAC is elevated on it. This means that there is no need to install AAC block masonry to be placed between the columns beneath the DPC level the plinth beam. DPC or damp-proof courses is a term used to describe the material that is applied at the basement level to stop the flow of moisture through floors and walls.

Load-bearing is a method of constructing low-rise structures with a low rise. The thickness of walls and the dimensions of the AAC blocks are essential when it comes to load bearing walls. Additionally, the location of these blocks is an art that requires the expertise of. It is crucial to design the wall by an experienced structural engineer.

AAC blocks installation

The process of constructing AAC blocks is comparable to the traditional concrete bricks. The positioning of AAC panels requires the assistance of cranes. Based on the finishing, these panels may be attached directly or by mechanically attaching them to the surfaces of AAC.

Blocks for AAC: Where can they being used?

AAC blocks are used extensively for building apartments, as well as other residential, industrial and commercial structures, like hospitals, hotels, offices and schools. Because of their outstanding heat insulation capabilities, AAC bricks find application for both exterior and interior construction. They are perfect for structures with high rises.

AAC blocks vs red bricks

AAC blocks are sought-after by builders in India because this modern building material has advantages over traditional bricks due to a variety of reasons.

First of all, bricks weigh more than concrete and the use of them in construction results in increased costs and waste. Additionally, the increasing cost of kiln fuel could influence the total cost. AAC blocks, on contrary, are light. AAC blocks are light in weight. AAC blocks is around 80 percent lower than bricks made of red and can result in a decrease in the usage of steel and cement, thereby making it more cost-effective. In addition, they are eco-friendly, AAC blocks ensure better durability, as well as better thermal and sound insulation as in comparison to bricks.

Blocks of AAC vs CLC blocks : which one is more effective?

CLC (cellular lightweight concrete) blocks are made by the cellular light concrete (CLC) or foam concrete. It is a concrete that is lightweight constructed by mixing flyash slurry and cement with foam that has been pre-formed. CLC blocks are generally less expensive in comparison to AAC blocks. In the area of compression strength AAC blocks are superior to CLC blocks.

AAC Blocks Background and history

In the 1920s, Dr. Johan Axel Erikkson, along with Professor Henrik Kreuger, developed AAC blocks. After patenting the process of manufacturing around 1924 AAC blocks began to be manufactured in full force beginning in 1928 in Sweden.

At present, AAC blocks manufacturing on an extensive scale as a building material is carried out across nations like those of the United States of America, Russia, Germany and India. The demand for AAC blocks is growing across many countries of Asia as well as India due to the growing demands for housing units and commercial space. But demand for this type of construction material is developing in India.
