Process for producing concrete

A process for producing concrete comprising mixing barkhan sand with a fuel selected from the group consisting of a liquid fuel and a solid fuel, and with a plastic binder selected from the group consisting of clay, loess, loam and surfactant which liquifies and reduces water-consumption of the composition, said plastic binder being present in an amount sufficient to provide for granulation of said sand and said fuel and, the components of the mixture being in the following proportions in percent by weight:

• barkhan sand:
• 95 to 30
• fuel:
• 3 to 20
• plastic binder:
• 2 to 60;
• granulating the resulting charge;
• calcining the granules at a temperature ranging from 1,000.degree. to 1,600.degree. C.;
• crushing the calcined material;
• mixing the crushed material with cement and water, cement being used in an amount of from 10 to 100% by means of the calcined material and water in an amount of from 10 to 60% by mass of the total of the calcined material and cement.
