Mechanical and fracture properties of geopolymer concrete with basalt fiber using digital image correlation

This paper investigates the mechanical and fracture properties of basalt fiber reinforced fly ash geopolymer concrete with different length (3 mm, 6 mm, 12 mm and 18 mm), which were tested by means of compressive strength test, splitting tensile strength test and three point bending test. The fiber reinforced mechanism was characterized by SEM. Simultaneously, the strain field and displacement field of FAGC were explored by using of digital...
