Abstract:In order to study the influence of basalt fibers incorporation on the stress performance of high strength and self-compacting concrete columns, 3 HSCC columns (as the control group) and 12 basalt fiber modified HSCC columns were made with parameters of 0.1%, 0.2% of basalt fiber volume content and 15mm, 30mm of fiber length respectively to conduct the axial compression experiment. The results show that the ultimate bearing capacity of HSCC columns was improved after incorporating basalt fiber. The maximum improvement of 16.9% comes from the HSCC column with fiber length and basalt fiber volume content of 15mm and 0.1% respectively. Under the same load, the appearance and development of cracks in HSCC columns are delayed, and the strain and deformation decrease. When the ultimate bearing capacity is reached, the corresponding compressive strain and displacement increase by 24.3% and 20.6%, respectively, and the ductility of HSCC columns is significantly improved.
