Compressive behavior of steel-polyethylene hybrid fiber reinforced cementitious composite
A hybrid fiber reinforced cementitious composite (HFRCC) was produced by mixing steel fiber (SF) and polyethylene fiber (PE) together in the cement matrix with an appropriate ratio. Under the same PE volume percentage, the effect of various SF aspect ratios (30, 50, 65, 83.3, and 108.3) and volume p...

| description | A hybrid fiber reinforced cementitious composite (HFRCC) was produced by mixing steel fiber (SF) and polyethylene fiber (PE) together in the cement matrix with an appropriate ratio. Under the same PE volume percentage, the effect of various SF aspect ratios (30, 50, 65, 83.3, and 108.3) and volume percentages (0%, 0.3%, 0.6%, and 0.9%) on the compressive behavior of HFRCC was experimentally studied. The results indicated that the aspect ratio and volume percentage of SF had little effect on the elastic modulus of HFRCC. With the addition of SF, the maximum increase of compressive strength and peak strain reached 33.82% and 24.29%, respectively. And the HFRCC presented maximum compressive strength and peak strain when the aspect ratio of SF was 108.3 and the volume percentage was 0.6%. In order to reveal the compressive constitutive relationship of HFRCC, a piecewise function was adopted based on the comparison of existing theory and furthermore in which the fiber reinforcing index, compressive strength, peak strain, and elastic modulus had been introduced. It is concluded that the proposed compressive constitutive model has more agreement with test data. |
