摘要

摘要: 为了研究高流态高性能混凝土开裂后其导电性与开裂电阻之间的关系,以碳纤维和钢纤维作为复相导电材料与结构材料加入混凝土中用以改善其导电性能、韧性与抗裂性。通过试验分析,建立了混凝土梁在受弯荷载作用下电阻变化率与裂缝宽度的关系。研究表明:开裂后,混凝土电阻变化率与裂缝宽度呈线性关系。

Abstract: In order to study the damage after concrete cracking,the influence of the combined use of steel fiber and carbon fiber on the conductivity and crack resistance of concrete beam under flexural loading were investigated．Carbon fiber and steel fiber were added as diphasic conductive materials to produce the electric conductive and ductile concrete.It was reported the experimental and analytical work associated with establishing the crack width in relation to the fractional change in resistance of electric conductive concrete．After cracking,the electrical resistance change was found to correlate linearly with the crack width on the tension side of concrete beam．
