Mechanical Properties and Microstructure of Basalt Fiber Reinforced Concrete Under the Single-Side Salt-Freezing–Drying–Wetting Cycles
Highlights 1. Through the design of this single-side salt-freezing–drying–wetting cycle test method more truly reflects the impact of the service environment on concrete (ordinary concrete, basalt fiber reinforced concrete). 2. Through the comparative study of macroscopic mechanical properties and microstructure, the failure mechanism of concrete (ordinary concrete, basalt fiber reinforced concrete) and the main strengthening mechanism of basalt fiber under single-side salt-freezing–drying–wetting cycle were revealed. 3. The correlation calculation proves that the mechanical properties of concrete (ordinary concrete, basalt fiber reinforced concrete) are highly correlated with porosity, pore size distribution and critical pore size under single-side salt-freezing–drying–wetting cycle. 4. The sensitive aperture of compressive strength and splitting tensile strength of concrete (ordinary concrete, basalt fiber reinforced concrete) under single-side salt-freezing–drying–wetting cycle is calculated, which provides a reference for further comprehensive analysis and calculation.
