Fly ash combined with a bonding agent, an air entrainer, water, and a foaming agent which forms gas as a result of a chemical reaction within the mixture; allowed to foam and harden, produces a material that is relatively strong and light, has good structural strength, and is resistant to fire, freezing, and thermal shock. Since the major component, fly ash, is a waste product, the material is also inexpensive, and can help alleviate a waste disposal problem. The composition can be handled and fabricated much like concrete, and standard concrete components can be used to modify its strength, setting time, density, color, and water reistance. It may also be formed or crushed for use as a light weight aggregate.
