1) How much power consumption is required for running AAC Blocks machinery plant?

A) 50 hp to 100 hp depends upon capacity of plant


2)How labor force is required in running a AAC light weight brick machinery plant?

A) 15 to 20 members need


3) Is to operate boiler certified person need?

A)yes,two certified boiler operator needed and pay more than RS 10,000 for each


4) In what sizes are AAC light weight bricks available for sale?

A)Length Height Thickness

2 feet 9 inches 4inches

2 feet 9 inches 6 inches

2 feet 9 inches 8 inches


5) What type of cement grade can use in AAC light weight bricks manufacturing?

A)53 grade ordinary Portland cement (OPC) is used for manufacturing AAC bricks.


6) What type of fly ash can be used for AAc bricks production?

A)  We should use fine fly ash, which is available in thermal power plants. (It is also available in certain industries free of cost. You got make to make your own transport arrangement).This raw material is one hundred percent (100%) suitable for AAC bricks production.


7) What type of conveyor can be used in AAC bricks machinery plants?

A) Here are two types of conveyors that can be used:

*Belt conveyor for fly ash * Screw conveyor for cement
However, our suggestion would be to use only belt conveyor for both,

which is sufficient. It is better to avoid screw conveyor for cement.



8)Are AAC Blocks Load-bearing?

Yes, this is very true. The AAC Blocks and panels with a minimum of 8  inches thickness are most suitable for load-bearing applications.However, this holds good when used by following our prescribed internationally accepted design aids and acceptable stress listings. The 6 inches AAC Blocks are used for interior load bearing applications. Several load bearing applications require vertical cores reinforced with debar and concrete. Moreover, code requires cores at corners, doors and windows. For design information please, consult our Technical Manual or Contact us at:  to request a technical manual and get all the required information. We, gladly look forward to your


9)What is the type of mortar that is used with AAC Blocks?

A)It is advisable to use Thin-bed mortar designed in particular for AAC Blocks. However, traditional sand cement mortar made at site can be used. It is delivered in powder form that can be mixed readily.Moreover,the raw material used is polymer modified Portland cement. It is exclusively designed to retain water from entering the pores of AAC blocks, which perfectly bond the AAC blocks together firmly. Moreover, to hold fast the blocks only a thickness of 2 to 3 mm thin mortar bed is needed. This is extremely thin joint, which also prevents heat loss and speeds installation. you can how to mix mortor in


10)Are the AAC Blocks safe to use and time tested?

Yes, AAC Blocks are extremely safe to use in construction work. Also,they are time tested. They are being used in construction work in Europe, ever since 1923. The technology shifted to Asian countries with its usage from the year 1972, in India. Moreover, AAC Blocks are not  made from toxic or hazardous material. It is the safest building product available. This has been confirmed by several tests have been conducted by laboratories with international certifications. It does not emit fumes or emit heat above the level of cooking food for eating. There is no waste produced during manufacturing as well. It neither contains nor emits toxic substances. The tests conducted in the laboratories areauthentic and hold international certification.



11)How far AAC Blocks in wall masonry is cost effective in comparison to brick wall masonry?

The size of the AAC Blocks is 9 times the size of traditional bricks use in construction work. Therefore,this result in substantial saving in cement due to less number of joints compared to brickwork,including plaster work finishing. Moreover, the AAC Blocks are made with technical specification that follows accurate measurements. The measurements are in standard form. Thus, resulting in less consumption of Plaster,POP, or Putty finish, which reduces the cost construction of walls in AAC Blocks.

Over all the dead load reduces because of its lightweight and low density.Thus, there is considerable low steel consumption in structural construction work when compared to clay masonry in conventional form. Indeed, there is an increase in the carpet area as well. It is by a margin between 3 per cent to 5 per cent as well. Moreover, it also depends on the design and type of construction done.The construction speed is high and there is a big saving in operating cost.It is due to fact that the AAC Blocks are light weight, including their size is much bigger. This is seen in the reduced cost in maintenance taking into consideration the power consumption bills and insurance.

12)How do you install concealed wiring in walls constructed by AAC Blocks?

The installation of electrical wiring in AAC Blocks construction is done by following a . After the construction of the walls is done, the electrician gives markings on the required areas where the wiring travels. It is indicated directly on the walls. There are two types of procedures followed. One is manual and the in the other an electric outer is used to cut channels on the inner portion of the walls. Thereafter, the electrician does the installation of the wiring. Next, the AAC Blocks wall is filled with regular plaster. This gives a clear smooth finish to wall that is free of cracks in them. Moreover, it does not require any pre-planning.So also the changes are made easily. The extra number of receptors,receptacles, including switches can be additionally installed by the routing method wherethe conduits are made on the AAC Blocks.
