The invention relates to the field of building materials industry and construction and can be used to strengthen soil and road and airfield pavements, as well as to make mortars and concretes. Known as stonework, including Portland cement clinker 80%, ashes containing high amounts of silicon, aluminum, iron and low sulfur content and having losses during procuring) less than 6% in an amount of 20% and in excess of 100% gypsum IJ. .

A disadvantage of the known residents is the use of scarce portland cement and high quality requirements for the ash.

 It is also known to include the waste of asbestos-cement production in the wet state of 35-65%, gaps containing adium waste of the production of hydrofluoric acid 35-65%; when it contains 85-90% of gypsum, 2% calcium oxide hydrate, and iron oxide oxides and alkshini, as well as in excess of 100% active mineral, additive up to 1.5% 23.

This is the most true, near KIM ito technical entity:; The achievable result, in the disadvantage of this idle, is a relatively low strength.

The purpose of the invention is to increase: strength, in the grip.

. The goal is achieved | 0 by the fact that the cement, including asbestos, cement waste and the gypsum-containing component contains asbestos-cement waste, heat treated at a temperature of 120-150 s, E as gyro containing the component of borogips and
