纤维增强混凝土(Fiber Reinforced Concrete,简称FRC)是一种通过向普通混凝土基体中掺入短纤维材料,以提高其抗裂性、韧性和耐久性的复合材料。以下为详细解释:
纤维增强混凝土由水泥基体(如普通混凝土)和均匀分散的纤维材料组成。纤维作为增强相,可弥补传统混凝土脆性大、易开裂的缺陷。根据美国混凝土协会(ACI 544.1R)定义,纤维长度通常为6-50毫米,掺量占总体积的0.1%-3%。
纤维通过以下方式增强混凝土性能:
多项实验表明,掺入1.5%钢纤维可使混凝土抗弯强度提高30%-50%(ACI期刊《Materials Journal》第119卷)。中国国家标准化管理委员会GB/T 21120-2018亦规定了纤维混凝土的测试方法。
纤维增强混凝土(Fiber Reinforced Concrete,FRC)是一种通过向混凝土基体中均匀掺入短纤维形成的复合材料,旨在提升传统混凝土的力学性能和耐久性。以下是其详细解析:
如需进一步了解具体纤维性能对比或工程案例,可参考权威文献或行业标准(如ACI 544报告)。
