Abstract
The mainobjectiveofthisresearchistoinvestigatethepossibilityofusingferrocement concretetorehabiliteethedamagedplateswhichfailedunderimpactload.Thecurrent workpresentsthecomparisonbetweentheresultsofthe first crackloads,theultimate loads andthedeflections inthecasesoftheimpactandstaticloads.Seventeenplateswere damaged underimpactload [3TD$DIF][1], whichhavingthedimensionsof500500and25mm thick. Theplatesweresubjectedtoimpactloadby1.15kgsphericalsteelballunderits height 1.12matthecenterofthetestedplates.Theferrocementplateswerereinforcedwith skeletal steelbarsweldedgalvanizedmeshesandexpandedsteelmesheswithskeletal steel bars. Theplates weretesteduptofailure.Thedamagedplateswererepairedby employing concretemortarandtwolayersofgalvanizedsteelmesh(300*300mm)atboth the topandbottomfacesofthedamagedplateandtiedwithonelayer(500*500mm)by means ofshearconnectorsatbothtopandbottomofthedamagedplatebyusingLscrew bolts withimbedded fisher.Therehabilitationplates(500*500*50mm)weretested simply supportsalongitsfoursidesandsubjectedtocentral flexuralloadingsuntilfailure.
