In modern conditions, one of the ways allowing the construction company to be competitive in the market is the use of modern high - quality and, at the same time, cheaper building materials. Many technogenic formations, in particular solid waste are valuable technological raw materials and can be involved in technological redistribution in order to obtain composite building materials. In the production of crushed stone, sands from lithoid pumice and perlite, it is advisable to produce separation and separate obsidian. In this case, the separated obsidian turns into production waste. The expantion of obsidian will allow to obtain a large porous ultralight material and thereby solve environmental issues - recycle production waste. On the base of expanded obsidian, it is possible to obtain new types of effective composite thermal insulation and acoustic materials (cellular concretes and acoustic plasters), which have high performance properties and expand the range of effective building composite materials.
