Abstract

A study was conducted to add agricultural and industrial wastes and nanomaterials to concrete combined with carbon fibers to improve the mechanical and electrical properties of concrete for use in advanced applications in electromagnetic shielding and conductive concrete. Carbon fiber was used at 2 wt.% of sand and ( electrical induction furnaces slag(EIF), carbon nanotube (CNT), steel wool fibers, prepared corn husks) at 0.5 and 1 wt.%. of cement. The results of using 1% of steel wool with carbon fibers showed the highest percentage of compressive strength when tested at 3,7, 28 days of age, the DC conductivity and electrical resistance of samples was measured at the age of 7 days. The sample containing the CNT provided the best performance in this test and the results are also good for the sample containing steel wool.
