Title of the articleThe requirements to raw materials for obtaining hydraulic binder with low temperature calcination
Abstract.The analysis of the literature is showed, that by raw material for obtaining hydraulic binders with low temperature calcinations (hydraulic lime and romancemetnt) in various time were used natural and artificial the carbonate-clay mixes with the contents MgO up to 21 %. The russian specifications for raw material and the standards on romancement in the technical literature are absent. The critical analysis of the requirements to raw material for portlandcement and the conducted researches of raw material РТ have allowed to generate the requirements on a structure of raw material for obtaining low temperature calcinations hydraulic binders (hydraulic lime and romancemetnt). Is established, that mineral and chemical compositions the carbonate – clay raw material of a series of deposits of Tatarstan is suitable for obtaining hydraulic binders with low temperature calcinations. The technical properties of hydraulic binders were established, including mark on strength. The mark of romancement – «200». Group of lime – hardly hydraulic, strength – 13 МPа. Group of lime – poorly hydraulic, strength – 7,5 МPа. Values of strength not less, than for existing modern analogs.
Keywords.Carbonate and clay raw materials, composition, requirements to raw materials, calcinations, hydraulic lime, romancement.
