Thermalite blocks are what is known as Aerated Concrete and in Europe, GasBeton or PorenBeton. Basically a giant rectangular "wagon " is filled with a slurry of Cement, Sand, Pulverised Fuel Ash, Lime, Aluminium Powder, Anhydrite and hot water and the "mix" rises like a giant grey cake full of bubbles. This cake is then cut into building blocks, put into an autoclave and the result is an extremely light weight, (the lightest floats in water)highly insulating, but very strong building material. Other manufacturers use Silica Sand to replace all or part of the PFA content, but this is obviously less environmentally friendly. Silica Sand-based blocks tend to be white in colour.
