引用本文摘 要：為研究導電混凝土受彎過程的機敏性，在混凝土中摻入碳纖維和石墨來改善其力學及機敏性能，試驗研究了摻碳纖維和石墨導電混凝土的力學性能，建立了導電混凝土在受彎過程中荷載-撓度-電阻變化率的關系。在導電混凝土中適量用石墨代替碳纖維，可在不影響其力學性能的同時提高導電混凝土機敏性，對石墨-碳纖維導電混凝土撓度-電阻變化率進行擬合，得到撓度與電阻變化率關系的經驗公式，且相關性較好。 Abstract: In order to study the conductive concrete alertness bending process, graphite and carbon fiber were added to concrete to improve the mechanical and electrical properties. Experimental study on mechanical properties of graphite and carbon fiber electrically conductive concrete is carried out, and the load-deflection-resistivity change relationships of conductive concrete in the flexural load process are established. The results show that the right amount of incorporated graphite instead of carbon fiber in the conductive concrete can increase the alertness of conductive concrete without affecting its mechanical properties. The empirical formula of the relationship between the deflection and the rate of change of resistance of the graphite-carbon fiber conductive concrete is obtained, and the correlation is good.
