... the study, it is clear that basalt fibres can be used to reinforce mortar as the fibres remain unaffected up to 500 °C. Minimal increases in flexural strengths and compressive strengths were measured with the addition of basalt fibres at both ambient and elevated temperatures. SEM pictures revealed fibre...

... of the room temperature strength or 24 MPa. Microstructure analysis was conducted using a high-resolution scanning electron microscopy (SEM) model Quanta 650 FEG with an accelerating voltage of 15 keV. Relatively small, flat broken samples selected randomly from compression tests were analyzed without any...
