Abstract

Abstract

The experiments of the mixing of macro-synthetic fibers and polypropylene fibers, the mixing of steel fibers and macro-synthetic fibers reinforced shotcrete on the compressive strength and flexural strength were carried out, whose mechanical properties were compared with those of baseline group and single fibers group, The results show that the compressive strength, flexural strength, flexural compression ratio of hybrid fibers shotcrete are more obviously improved than those of single fibers shotcrete, and it can give full play to the superimposed effect.When the mixing contents are 0.7% of steel fibers and 0.3% of macro-synthetic fibers, the strength and flexural compression ratio of shotcrete are the best, and it is effective to make up for the disadvantages of steel fiber with its easy rust, heavy weight and high cost etc.
