Note: C40-6-0.1 is the ID of specimen. C40,C50,C60 refer to the concrete grade;6,18 refers to the length of chopped basalt fiber yarn is 6mm,18mm, respectively.0.1,0.2,0.3,0.4 refer to the basalt fiber mixed with rate of is 0.1%,0.2%,0.3%,0.4%, respectively. If there is no number following the concrete grand number means the tests is reinforced without basalt fiber. The rest Numbers reference to the above method.
