STEEL FIBRE TREATMENT TO IMPROVE BONDS

The article describes tests carried out to determine the effect of various wire treatments on the flexural tensile strength of a fiber-wire reinforced mortar. A scanning electron microscope was used to assess the effect of the treatments on the wire and also on the wire-paste bond. Three basic types of fiber-wire were used-a plain carbon steel wire 25 mm long and 0.38 mm diameter, and two types of crimped wire. The plain wire treatments tried were (1) degreasing using sodium hydroxide and acetone, (2) surface roughening using rusting, heating to red heat, and dilute hydrochloric acid, and (3) surface coating using zinc. It was concluded that fiber-wire concrete can only be considered as an alternative to normal reinforced concrete if tensile strength increases of 400-500% over plain concrete can be guaranteed. /TRRL/
