Annotation: The results of studies on the fine-grained concrete modified gypsum cement binder and agreggate of continuous particle size distribution have been given. It has been proved that the introduction of the gypsum-cement binder cullet and salts of unsaturated fatty acids or polyhydric alcohol leads to a modification of its structure, resulting in a change in the structure and mineralogical composition of the stone binder. As a modification of gypsum cement binder and the use of a continuous particle size distribution of the agreggate in the preparation of fine grained gypsum cement concretes modified binder increases the strength and water resistance of the concrete part. Agreggate with continuous particle size distribution obtained by mixing quartz sand tailings iron ores. Cumulative effect of modifications flabby gypsum cement – binder salts of unsaturated fatty acids or polyhydric alcohol and use of continuous particle size distribution of the aggregate exceeds the effect of each factor is applied independently.

Keywords: fine concrete, strength, filler, salt, alcohol.
