Autoclaved aerated concrete is cured in an autoclave-a large pressure vessel. In aircrete production the autoclave is normally a steel tube some 3 metres in diameter and 45 metres long.Steam is fed into the autoclave at high pressure, typically reaching a pressure of 800 kPa and a temperature of 180 AÂ°Ã¢. che pulverised flyash is usually milled to achieve adequate fineness. A small amount of anhydrite or gypsum is also often added. Autoclaved aerated concrete is quite different from dense concrete (ie: normal concrete) in both the way it is produced and in the composition of the final product.
Engineering design process. The engineering design process is a methodical series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered - though the part(s) that get iterated and the number of such cycles in any given project may vary.
