The author has developed materials and technologies of incinerator's ash and slag (IAS) in combination with other industrial wastes (all kinds of slags dumped by the iron and steel industry, liquid, sludge, and powdered wastes of chemical, textile, paint and varnish, petrochemical, engineering, iron and steel, and other industries). The materials have very high water and frost resistance. All of the ecologically burdensome components became chemically strong binded in insoluble compositions in acid, neutral and alkaline environments. The developed materials from these wastes can be used as lean concrete with unusual structures without binders like cement or lime. They can be used instead of sand, crushed stone, gravel, and all other traditional natural inert materials for the construction of bases of waste disposal sites, roads, airfields, darns etc. and other types of construction with a high economical efficiency. The "know-how" of the compositions and technologies are available. The patent of Russia is pending.
