Description
Summary:In order to preliminary investigate the opportunity to whole substitute natural aggregates of conventional concrete with steel slag and scrap tire particles. Volume deformation, compressive and flexural strength of concrete containing EAF slag and (or) scrap tire particles as aggregate were experimentally investigated by strength test according to the specification of GB/T 50081-2002 and unrestrained specimens volume deformation test. The results indicate that the mechanical strength of steel slag concrete is acceptable, though slightly lower flexural strength than that of conventional concrete. The expansion induced form steel slag using as both coarse and fine aggregates in concrete may lower the shrinkage and expansion to a certain extent. By partial substitution of fine steel slag aggregate with scrap tire particles, both the mechanical strength and the volume stability of scrap tire particle modified steel slag concrete are satisfactory, with similar strength properties to conventional concrete and obvious lower volume deformation change.
