Aero Bricks is the First manufacturer of Autoclaved Aerated Concrete(AAC) in Nepal. Established in 2015, the production unit of the company is situated in Chitwan. The company has the capacity to produce 450-500 cubic meter of AAC Blocks per day using fully automated German technology. AAC is a highly cellular light weight material produced from a mixture of cement, sand, lime, alumina and water and is one of the most reliable building products in the market.


Aero Bricks Company Pvt. Ltd. is fully committed to provide international standard products and value for money to its customers

Initially developed by Swedish Architect, Alex Eriksson in 1920's, Autoclave aerated Concrete(AAC) is one of the light weight building materials manufactured as blocks and panels from all natural ingredients.


AAC Blocks and Panels has been in use in Europe over 90 years with rapidly growing market shares in countries all around the globe. AAC Blocks and Panels are widely used in commercial, industrial and residential construction.


AAC blocks and Panels are the perfect alternative to the conventional practices which matches demand of modern construction

AAC is a precast product manufactured by combining sand, cement, lime, gypsum, water, and an expansion agent - aluminium powder, and pouring it into a mould.


In structurally reinforced AAC products like lintels or roof panels, steel rebar or mesh is also placed in the mould.


Once added to the concrete, the aluminium powder reacts with the silica, resulting in the formation of millions of microscopic hydrogen bubbles. The hydrogen bubbles cause the concrete to expand to roughly five times its original volume.


The hydrogen subsequently evaporates, leaving a highly closed-cell aerated concrete, then cut into which are further steam and pressure cured in an autoclave.

AAC products consist of load bearing, non-load bearing and cladding applications.


Complete load bearing applications, however, are limited to low-rise construction.


Cladding and large panels are available to take advantage of AAC’s insulative, fire proofing, and other benefits on mid- and high-rise projects.


The large wall, floor, and roof panels, measuring up to 20 feet long, 2 feet wide, and in various thicknesses, are also used in load-bearing capacities and are common in commercial and industrial applications.


The remainder of the AAC system consists of blocks, also called “units” which are stacked using thin-set mortar, as opposed to the traditional cement-based mortar.
