With unique foam excitation technique, coal ash and other waste materials are mixed together in a scientific proportion, then they will become gold bricks—high-performance building blocks which can float on water with many advantages of lightweight, environmental protection, energy-saving and thermal insulation after going through many techniques of compulsory stirring, activation, foaming, output, casting molding. Special foaming agent is composed of several chemical raw materials in a certain proportion that are easy to buy. It will become light after foaming which is much more effective than that of most foaming agents sold in the market, but the price of it is 50% lower than that of most foaming agents sold in the market. High efficient curing agent is composed of several chemical raw materials in a certain proportion that are easy to buy, which greatly reduces cement quantity and cost. It has advantages of high strength and light weight, and enables non-autoclaved blocks (bricks) to reach and exceed the required strength of steam-cured blocks; MS innovative forming non-autoclaved blocks new molding technology, moulds can arbitrarily change the size of blocks in order to adapt to fit around the block sizes that walls need, which reduce the cost of moulds, and are convenient.
