We offer high quality and precisely designed bricks manufactured with Autoclaved Aerated Concrete (AAC) - a path-breaking technology in the construction Industry. Autoclaved Aerated Concrete (AAC) blocks also known as Fly ash Light weight Brick or Block. It is a lightweight, precast building material that simultaneously provides structure, insulation, and fire and mold resistance We offer durable and Eco-friendly construction materials.
AAC (Autoclaved Aerated Concrete) is a certified green building material. These precast concrete blocks are extremely lightweight and widely used for internal and external construction.
Presence of uniform air pockets in AAC blocks results in significantly less weight compared to the clay bricks. This leads to not only lower costs in transportation but also in lower dead weight of the structure and hence contributing to lower requirement for steel and cement in building the structure.
AAC blocks have the compressive strength in the range of 3.0-4N/m2 compared to clay bricks that have just 2.5-3N/m2. The blocks can be efficiently used as a building material for hospitals, schools, high-rises and other structures.
AAC block weighs almost around 80% less as compared to the conventional red brick ultimately resulting into great reduction of deadweight. Further, the reduced deadweight results into reduction of the use of cement and steel which helps great in cost savings
High thermal insulating qualities. The thermal conductivity of the AAC blocks helps maintaining the inner temperature to be warm during the winters and cool during the summers which ultimately leads to savings in air conditioning load and consequently enhanced energy efficiency.
The porous structure of the AAC blocks results into enhanced sound absorption. The Sound Transmission Class (STC) rating of the AAC blocks up to 45 db. Thus, AAC blocks have been the most ideal material for the construction of walls in auditorium, hotels, hospitals, studios, etc.
As the AAC block is very easy to handle, can be easily used to cut and align the AAC. Moreover, the AAC blocks come with larger sizes and fewer joints. This ultimately results in faster construction work as the installation time is significantly reduced due to fewer amounts of blocks and the masonry amount involved is also lowered.
Depending upon the thickness of the Autoclaved Aerated Concrete (AAC) Blocks, they offer fire resistance from 2 hours up to 6 hours. These blocks are highly suitable for the areas where fire safety is of great priority.
The light weight property of the AAC blocks results into higher steadiness of the AAC blocks in the structure of the buildings. As the impact of the earthquake is directly proportional to the weight of the building, the building constructed using AAC blocks are more reliable and safer.
The AAC products, because of their cellular and discontinuous micro structure are superior to the normal clay brick in resistance of water penetrability and thus the external surface of AAC walls provides superior resistance to moisture penetration than the traditional clay bricks.
AAC blocks are highly superior in terms of the strength. Higher level of strength of these blocks gives higher stability to the structure of the building. AAC is manufactured from non-biodegradable materials, which neither rot nor attract mould, keeping interiors clean and durable.
The process of manufacturing AAC Blocks ensures constant and consistent dimensions. Factory finished blocks provide a uniform base for economical application of a variety of finishing systems. Internal walls can be finished by direct P.O.P., thus eliminating the need of plastering.
Autoclaved Aerated Concrete (AAC) Block consist of the inorganic material in its constitution that helps preventing/avoiding termites, damages or losses.
