Influence of basalt micro-fibres on the abrasion resistance of concrete in hydraulic structures

Abstract In hydraulic structures, abrasion resistance can be a significant driver in concrete specification. Basalt micro-fibres represent potentially sustainable construction product and have been shown to provide various benefits concrete, however the implications for hydrodynamic are date unclear. This paper is first investigation of its kind examine basalt fibre-reinforced (BFR) concretes using ASTM C1138 underwater test method. Towards this, incorporating fibre dosages 0.5, 1, 1.5 3 kg/m were tested. The relationships between fundamental mechanical properties evaluated. For particular examined, it found that based on Shapiro-Wilks tests at 95% confidence, loss BFR followed normal distribution; use contents up did not effect resistance, compressive tensile splitting strengths, as well modulus elasticity. It concluded micro-fibre used their other attributes such controlling bleeding, shrinkage plastic cracking structures without deleterious effects resistance. regression models proposed predict from only 48 h strength 24 both
