MELT EXTRACT STEEL FIBRE REINFORCED SPRAYED CONCRETE

A series of trials were carried out to investigate the suitability of melt extract stainless steel fibres as a reinforcing material for sprayed concrete. Three fibre dispersing techniques were studied and from the test panels sprayed, information was obtained on fibre rebound and the effects of fibre type and content on compressive, flexural and splitting strengths. Rebound of the drawn wire fibres was found to be twice that of the melt extract fibres on plywood panels and approaching two and a half times on rock. The addition of steel fibres produced increases in compressive and flexural strengths, typical values for a 7.5% fibre sprayed concrete being 15% and 55% respectively although increases of over 120% were achieved. The splitting strength of cores was investigated as a possible form of quality control to provide informationon tensile properties of fsc. Results indicated a linear relationship between flexural and splitting strengths. (Author/TRRL)
