FAQs
Q.Is AAC block time tested and safe ?
A. Yes, AAC Blocks are extremely safe and time tested , they are being used in construction since 1923 in Europe and in India they are being used since 1972 , Tests conducted by independent laboratories shows that AAC is not hazardous or toxic.
Q. Does installation of AAC blocks require a specialized mason ?
A. No,the application procedure is similar as with the conventional red/clay bricks and hence any ordinary mason can carry out the AAC block wall work with slight training. IS:6041 (for AAC Block masonry) lays down the procedure for application of AAC blocks.
Q.Does AAC provide the strength as provided by traditional red/clay bricks ?
A. Buildings built till few years back were load bearing structures, i.e. the weight of the structure was borne by the walls of the building, hence high strength was required in the wall. However, buildings constructed today are non load bearing structures, i.e. the weight of the structure is borne by the beams and the pillars and not the wall. Walls of today acts just as a partition. Therefore, AAC provides adequate amount of strength as required by the structure of today.
Q.Can an AAC block wall bear the load of wall hung fixtures and furnitures ?
A. Yes, AAC blocks can easily bear the load of wall hung fixtures and furnitures and nails can beeasily hammered like any other clay/red brick wall.
Q.Can concealed wiring be installed in AAC block wall ?
A. Concealing work becomes extremely easy and fast on an AAC block wall as channels can be easily cut out on the wall using simple conventional cutting tools or machines.
Q.Can an AAC block be cut or drilled ?
A. AAC bock can be easily cut with simple tools like a hacksaw or a handsaw, drilling can also be easily achieved.
Q.Can the smooth surface of AAC blocks attract and hold the plaster ?
A. Yes, AAC blocks attracts and holds the plaster like any ordinary clay/brick wall. Depending on the quality of masonry work, plastering can also be ommited and even if required, a plaster thickness of not more than 10mm is recommended.
Q. Can ordinary Cement-Sand joining mortar be used for joining of AAC blocks ?
A. Yes, ordinary Cement-Sand joining mortar in the ratio of 1:6 can be used for joining of AAC blocks. However, for additional benefits and cost savings, it is advisable to use Powerbond Thin-bed joining mortar/adhesive designed especially for AAC Blocks. It is delivered in ready-to-mix powder form. Just 2-3 mm thin mortar bed is needed to adhere the blocks.
Q. Do AAC blocks absorb more water compared to traditional Clay/red brick ?
A. No, AAC has a honeycomb structure and the pores in AAC are discontinuous. This prevents any capillary action taking place in blocks and hence does not allow water to pass through it and also absorbs less water compared to traditional red/clay bricks.
