Preparation of steel-basalt hybrid fiber reinforced concrete and its uniaxial compression performance
In order to investigate the compressive properties of steel-basalt fiber hybrid reinforced concrete at long age,this paper changes the volume of steel fiber and basalt fiber admixture to prepare 9 groups of specimens for uniaxial compression test,the results show that:①Concrete specimens with 1％volume admixture of steel fibers and 0.6％volume admixture of basalt fibers has relatively good damage patterns with compressive strength,peak strain,and axial compressive toughness ratios;②Fiber on the energy consumption of concrete materials is to play a positive role in enhancing,mixed with fiber,volume mixing of 1.5％of steel fiber and volume mixing of 0.4％of the energy consumption of the best effect of enhancement;③When mixing steel fibers and basalt fibers,basalt fibers have a greater effect on the compressive strength of concrete,steel fibers have a greater effect on the peak strain of concrete,and the axial compressive toughness ratio of concrete is affected to a greater extent by steel fibers;④The relationship between the compressive strength,peak strain and fiber volume admixture of concrete is fitted based on the test data.
