|fibrous concrete;纖維性混凝土
纖維增強混凝土(Fiber Reinforced Concrete,簡稱FRC)是一種通過向普通混凝土基體中摻入短纖維材料,以提高其抗裂性、韌性和耐久性的複合材料。以下為詳細解釋:
纖維增強混凝土由水泥基體(如普通混凝土)和均勻分散的纖維材料組成。纖維作為增強相,可彌補傳統混凝土脆性大、易開裂的缺陷。根據美國混凝土協會(ACI 544.1R)定義,纖維長度通常為6-50毫米,摻量占總體積的0.1%-3%。
纖維通過以下方式增強混凝土性能:
多項實驗表明,摻入1.5%鋼纖維可使混凝土抗彎強度提高30%-50%(ACI期刊《Materials Journal》第119卷)。中國國家标準化管理委員會GB/T 21120-2018亦規定了纖維混凝土的測試方法。
纖維增強混凝土(Fiber Reinforced Concrete,FRC)是一種通過向混凝土基體中均勻摻入短纖維形成的複合材料,旨在提升傳統混凝土的力學性能和耐久性。以下是其詳細解析:
如需進一步了解具體纖維性能對比或工程案例,可參考權威文獻或行業标準(如ACI 544報告)。
