Introduction. Autoclaved aerated concrete is a versatile lightweight construction material and usually used as blocks. Compared with normal (ie: dense concrete) aircrete has a low density and excellent insulation properties.he 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.
Lesson Summary. The activation energy is the energy required to start a reaction. Enzymes are proteins that bind to a molecule (substrate) to modify it and lower the energy required to make it react. The rate of reaction is given by the Arrhenius equation.
what is the activation energy of a reaction? what happens when molecules collide with less energy than this?
