Abstract: The composition of the combined fine aggregate is developed. Researches on studying of efficiency of inclusion of fraction of 5 mm in structure of filler for fine-grained concrete are carried out. Optimum compositions of fine-grained concrete with the use of the combined filler are calculated. Rheological properties of concrete mix and physical and mechanical characteristics of concrete on the combined filler are defined.

Keywords: combined fine aggregate, spatial frame, concrete composition, workability, mode of heat-and-moisture treatment, medium density, water absorption, strength of concrete.
