FIELD: building materials, building industry.
SUBSTANCE: invention relates to binding agents based on ash from thermal electric power plant. Binding agent containing fly ash and lime involves additionally limestone and alkylidene phosphonic acid activated after mechanical-chemical treatment in the presence of lime wherein components are taken in the following ratio, wt.-%: fly ash, 82.0-92.0; lime, 3.0-9.0; limestone, 4.97-8.91, and alkylidene phosphonic acid, 0.03-0.09. Invention provides enhancing strength, hardiness and water resistance of material and decreasing content of lime. Invention can be used for strengthening soils, making bases and froze-protective layers in road dress or as self-contained building material.
EFFECT: improved and valuable properties of binding agent.
