Sound transmission class(STC) is 40 for 4-inch width and 45 for 8-inch width. Thermal resistance is 0.8 to 1.25 per inch of thickness Although we can cut aac blocks by the carpenter’s saw easily, it is time-consuming and requires particular labour for this specific work.Īlso, Read – What is WPC Board? – Advantages, Disadvantages, Uses Properties of AAC BlockĬompressive strength is 35 to 40 kg/cm2 as per is code 2185 We can’t hammer aac block for the service like chiselling because it may break.Hence several builders are using traditional building methods for the installation of an extra insulation layer. Northern European countries’ new building codes require a very thick wall if using aac block only.We have to use a large diameter wall plug, which has a higher cost than a standard plug. Its brittle nature requires long thin screws for wall hangings and cabinets and requires a drill bit or hammering in.

The cost per unit of AAC block is high, but overall, masonry cost is low because it requires less mortar for installation.AAC blocks have brittle nature therefore, they require more care than clay brick while handling and transporting.AAC blocks are well known for cracks after installation, which can be overcome by reducing the mortar strength.AAC blocks are non-load-bearing material hence it can be used only for partition walls.The weight of the standard size of a block, which is 600 × 200 × 200 mm is 15 kg.Īlso, Read – Silt Content Test For Sand Disadvantages of AAC Blocks The only by-product is steam made of non-toxic ingredients that do not exist gasses.įollowing the block, sizes are available in AAC Blocks. Mix productive use of recycled Industrial waste is a fly ash non-polluting manufacturing process. Hence helps in reducing the heating and air conditioning costs of a building. These blocks allow excellent thermal insulation due to tiny air pores and the thermal mass of blocks.

Minimum WastagesĪAC blocks have negligible breakage less than 5% hence utilization of blocks increases. These blocks are easy to install also set and harden quickly. Reduces construction time by 20% different sizes of blocks helps reduce the number of joints in wall masonry, lighter blocks facilitate more comfortable and faster construction. Blocks can be easily cut drilled nailed Miled and grooved to fit individual requirements available in custom sizes simplifying hydro sanitary and electrical installations such as pipes or ducts, which we can install after the completion of the leading construction.Īlso, Read – 10 Best Cement Companies In India Faster Construction
