摘要

This report presents the experimental investigation carried out to evaluate the211u001eperformance characteristics of basalt fiber reinforced concrete and basalt bar 211u001ereinforced concrete. The fibers and bars were supplied by Research and Technology 211u001eInc., Madison, WI. All the experiments were conducted following the ASTM 211u001estandards. The test program was conducted for fresh and hardened concrete 211u001eproperties. The frest concrete properties consisted of the following tests: 211u001eslump, Vebe slump, Vebe time, concrete temperature, air content and unit weight. 211u001eThe hardened concrete properties determined were compressive strength, static 211u001emodulus, flexural strength, load-deflection behavior, comparison of load-211u001edeflection curves, ASTM toughness indices, first crack toughness, post crack 211u001ebehavior, Japanese standard method for toughness indices and equivalent flexural 211u001estrength.
