Description
Summary:In this paper, the iron tailings powder, iron tailings sand and iron tailings gravel in Qian'an city are used to replace fly ash, river sand and gravel respectively as admixture, fine and coarse aggregates of concrete. Through mix design, the high-fluidity concrete with strength grade C25, C30 and slump of 180~200mm is prepared. The compressive strength of all kinds of concrete with iron tailings powder as admixture can meet the requirements of the corresponding strength grade. The basic strength properties of full iron tailings concrete are more prominent in all kinds of concrete with iron tailings powder as admixture, and are the closest to that of fly ash concrete.
