编织纤维格栅增强混凝土梁弯曲韧性指数的试验研究
EXPERIMENTAL TEST ON THE FLEXURALTOUGHNESS INDEX OF THE CONCRETE BEAMS REINFORCED BY FIBER GRIDGEO FABRICS
【摘要】 介绍了测定碳纤维格栅、碳/玻璃混杂纤维格栅织物增强混凝土复合材料的抗弯试验,绘出了它们的典型荷载挠度曲线.研究表明,纤维格栅织物可以明显提高混凝土的弯曲韧性指数和抗弯强度.
【Abstract】 The experiment on the flexural toughness index of the concrete composite Beams reinforced by the carbon and carbon/glass fiber gridgeo fabrics is introduced. The typical curve reflecting the relation between the pressure and the deflection of the two kinds of the beam is drawn. The experimental result proves that the concrete composite beams reinforced by fiber gridgeo fabrics have improved flexural toughness index and flexural strength.
