Abstract: Influence of the maintenance of fraction of 0–0,16 mm on mobility of mixes and strength of usual concrete with use of a small filler from mixe of fly-ash and slag of thermal plants, screening of granite and limestone are investigated. The expediency of replacement to quartz sand by fraction of 0–2,5 mm of fly-ash and slag of thermal plants, screening of granite and limestone are establish. It are show that the maintenance in screening to 10 % raised fractions of 0–0,16 mm, and to 20 % did not reduce strength of concrete.

Keywords: a small filler of concrete, mixe of fly-ash and slag of thermal plants, screening of granite and limestone, mobility of mixes and durability of concrete.
