Near-surface characteristics of fibre-reinforced concrete floors: an investigation into non-destructive testing

An investigation was undertaken on a wide range of factors affecting the abrasion resistance of fibre-reinforced concrete floors including concrete mix design, fibre shape, length and type, water-cement ratio, and curing regime. In addition to using the rolling wheel abrasion tester, several non-destructive methods such as initial surface absorption, impact resistance and hardness were included so that assessments could be made on their ability to predict the abrasion resistance of concrete floors. The subsequent analysis of the experimental data suggests that the impact resistance and hardness tests are more appropriate for this purpose.
