Performance of polymer-modified fiber-reinforced high strength concrete
Publication details: Thane ACC LTD 2021Edition: Vol.95(6), JuneDescription: 47-56pSubject(s): Online resources: In: Indian Concrete Journal - ICJSummary: This paper presents the results of polymer-modified fiberreinforced concrete (PMFRC). The various strengths considered in this investigation are compressive, flexural, and shear strengths. The regimes of dry air curing are 28 days and 90 days. The M-40 grade of concrete is used as a reference mix. The fiber content was varied from 1% to 10% by weight of cement at the interval of 1% with 5% constant dosage of SBR (Styrene Butadiene Rubber) polymer. Cubes, prisms, and push-off specimens were prepared and tested subsequently at the ages of 28 days and 90 days. The significant improvement in compressive, flexural, and shear strengths, as well as ductility and toughness is observed due to synergistic effect of polymer and fibers. The results of effect of number and pull-out length of fibers on failure plane are presented.| Item type | Current library | Status | Barcode | |
