Lightweight concrete is composed of porous aggregates. Such aggregates can be volcanic pumice or shale. A porous material can improve its thermal conductivity, reduce its density, and increase its resistance to corrosion.

Autoclave treatment is an important feature of lightweight concrete. It is produced through a chemical foaming reaction of aluminium powder and hydrogen gas. During the manufacturing process, air bubbles are formed with a diameter of approximately one mm.

Lightweight concrete is also used in construction of high-rise buildings. A few examples of these buildings are the Bank of America Building in Charlotte, N.C., and the Ieder Zijn Huis in Jette, Belgium.

Fakafehoanaki ki he sima angamaheni ., lightweight concrete has a lower specific weight, 'a ia 'oku 'uhinga ia 'e lava ke faka'ekonomika ange ki he ngaahi poloseki lalahi ange .. Pea mo e, 'oku toe lahi ange 'ene teke ki he uesia ..
