Fiberglass Rebar (GFRP Bar)

What is the difference between GFRP rebars and steel rebars?

主要体现在四个方面:物理性能方面,GFRP筋重量仅为钢筋的1/4,抗拉强度更高(≥600MPa),但弹性模量和抗剪强度低,是脆性材料,没有屈服平台。耐腐蚀与电绝缘方面,GFRP筋在酸碱盐及潮汐环境中永不生锈,且不导电、不导磁;钢筋易锈蚀,体积膨胀导致混凝土开裂。热导率与截线膨胀系数方面,GFRP筋导热性低,热膨胀系数更接近混凝土,温度应力小。施工连接方面,GFRP筋无法现场焊接,连接依靠专用绑扎钢丝、U型卡扣和工厂预制的弯折形状。
