Foam Cement or Autoclave Aerated Cement is in my opinion, the BEST building material in the world. In Germany for example, it is used in 60% of all buildings. It is an ultra light masonry product, weighing only 1/5 of the weight of ordinary concrete. It is composed of 1 part water, 1 part cement (which is powdered or ground limestone), 1 part non toxic dish soap. The detergent is foamed using air from a compressor and a pump or motor to agitate the mixture (I use a conventional drill and paint mixer to blend it all together and it works fine). The expansion of trapped materials results in air or oxygen molecules which comprise the majority of the material (I believe close to 80%) upon expansion. It's fire proof, water proof, insulating, bulletproof (U.S army used the foam for ballistic testing, look it up) and earthquake proof, hurricane and monsoon proof, impervious to insects, rodents provides acoustic insulation and is 100% free of toxic of harmful substances, which makes it 100% biodegradable and completely recyclable. It is all natural and produces no by products. Also, as if it weren't' enough, it won't rot, rust, corrode, warp under cold or heat or otherwise decompose in at least 30 years for my home so far. The future was invented in 1923, but the powerful lumber and steel industries of America have lobbied hard to keep AAC uncertified for U.S. building codes. But there's a bunch of countries in Asia and Europe that have awakened to this super accessible, high quality low cost housing. This is not the building material of the future, it can be the building of the present.
