Static Tests
Bending tests were performed in accordance with the ASTM C393 standard at a 1 mm/min loading rate using Shimadzu Universal test equipment with a 250 kN load cell. During three-point bending tests, load was applied with a 30 mm-diameter cylinder. The span length between the 30 mm-diameter supports was 80 mm. Figure 2 shows the application of load to the specimen.
