| Abstract [eng] |
Not autoclaved concrete is classified as lightweight concrete with a density of 200 to 1800 kg/m3. Poured concrete has characteristics such as high strength in weight ratio and low density. The use of acrylic concrete reduces the constant load on structures and foundations, saves more energy and reduces the cost of construction work. Also, in the production of construction products such as concrete blocks, etc., production and transportation costs are reduced compared to normal concrete, the porous concrete has the potential to be used as structural material for structures. According to the purpose, lightweight concrete is divided into thermal insulation with a density less than 500 kg/m3, structural - thermal insulation with a density of 500 - 1200 kg/m3, and structural ones. Their density is 1200 - 1800 kg/m3. Ship production - repair technology generates industrial waste that consists of metal and anti-corrosion coating dust. Their utilization is quite problematic, and it is looking for ways to cheapen and more efficiently utilize these waste. One of the possible solutions is the use of these wastes in the production of aerated concrete. With the increasing cost of energy resources, the production of autoclaved aerated concrete is becoming increasingly promising. However, its manufacturing technology is still being refined. This article is a brief overview of concrete, its constituents, production method and properties. The purpose of the literary analysis was to broaden and deepen the knowledge about the potential application of aerated concrete in the construction industry these days, using technogenic waste. |
