Aeroliance Exports is based in India and lists building materials on Global Trade Plaza. The company offers Autoclaved Aerated Concrete (AAC) blocks, described as lightweight precast units that provide thermal insulation, soundproofing, fire resistance and moisture proofing. The blocks are noted as three times lighter than red bricks and are said to reduce foundation load, structural steel consumption and mortar consumption. The supplier also lists fly ash, a finely divided powder from coal combustion that is processed for use in concrete mixes. The fly ash is presented as a pozzolanic material that can improve workability, increase long-term strength and enhance durability against sulfate attack and alkali-silica reaction. It is offered for applications such as ready-mix concrete, precast products, mortar, grout, soil stabilization, road construction and dam construction.
