Abstract
The use of non-metallic basalt fibre reinforced polymer (BFRP) bars in concrete structures has widely increased in the construction sector due to their high mechanical performance. However, BFRP bars have not been included in most design standards and specifications. This is due to lack of investigation on the performance of BFRP bars, in particular, their thermal stability when exposed to high temperature. In this paper, the thermal expansion coefficients of sand-coated basalt fibre reinforced polymer bars were investigated. The thermal stability of sand-coated BFRP bars were determined in the temperature ranging from room temperature to 3500C as per ASTM E228-11.The deterioration of fibre/matrix interface of sand-coated BFRP bars due to extreme temperature were observed using scanning electron microscopy. The experimental test results showed that the sand -coated BFRP bars were treated at extreme temperature, the deterioration of the interface between fibre and resin matrix bring significant reduction of the thermal properties.
