Sustainability of autoclaved aerated concrete (ACC)

Autoclaved aerated concrete (“AAC”), though not much known in the United States, is now one of the many building products being touted as “green” or “environmentally friendly.” This paper briefly examines the advantages and disadvantages of building with AAC, paying specific attention to the aspects of the product that may lend to its designation as a sustainable building material. ACC concrete block showing the cellular pore structure (Shi and Fouad 105) AAC is not a new building material; however it is new to United States of America. It originated from Sweden in the early years of 1920 as a result of a rise in demands of timber supplies; AAC is a lightweight building stone that is manufactured (Shi and Fouad 105). AAC is used in a large number of commercial, industrial, and residential applications. This material has been used in Europe for many decades. Also leading in the use is Middle East followed by South America and Australia. Autoclaved aerated concrete is a precast product manufactured by mixing silica, cement, lime, water, and aluminum powder, and pouring it into a mold. With respect to reinforced AAC products like roof panels, lintels, steel rebar or mesh is also placed in the mold. When added to the concrete, the aluminum powder reacts with the silica, forming millions of microscopic hydrogen bubbles (Shi and Fouad 105). The hydrogen bubbles make the concrete to expand relatively five times its original volume. The hydrogen then evaporates, leaving a tightly closed-cell aerated concrete. ...Show more
