Abstract
The performance of melt extract and wire fibre reinforced sprayed concretes produced at three field trials in the UK is reported. An emphasis was placed on measuring properties relevant to the applications of the material and in particular the effects of in situ fibre content and fibre type. Flexural strength was found to increase significantly with fibre content in a linear relationship from the unreinforced strength. Core compressive strengths of around 70 MN/m2 were achieved and increased slightly with in situ content. Toughness index, calculated from beam load/deflection curves, increased rapidly with fibre content to over 30 times that of the unreinforced matrix at 7% by weight. Two splitting tests on cores were investigated as possible methods of on site quality control and results indicated linear relationships between flexural and splitting strengths.
