Aerated light-weight concrete is composed of cement, fine aggregate, water and foaming agent. Grout made from slurry-type (sludge) mortar (a mix of cement, soil and water) mixed with foamed bubble is called Aerated mortar, while Aerated light-weight concrete made without soil is called Aerated cement slurry. Since it has a property of concrete and soil, unit weight and unconfined compressive strength can be set arbitrarily by changing material configuration, which meets required unconfined compressive strength at 2.0N/mm² or below. Aerated light-weight concrete has excellent characters such as lightweight, fluidity, high construction performance and self-controlling, which can be utilized in various civil engineering works such as lightweight banking, shield filling, backfill grouting, void filling, etc. Since our company's establishment in 1961, we have achieved the Aerated light-weight concrete construction results of more than 10 million CBM in the fields of building and civil engineering.
