Nothing to do with the coming ice age, but I find this concept fascinating.
Commenting on youtube, Mark Soares thinks Foam Cement is “the BEST building material in the world.”
“It is an ultra light masonry product weighing only 1/5 of the weight of ordinary concrete,” says Soares. “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.”
Soares adds that “it’s fire proof, water proof, insulating, bulletproof, 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.”
