Thm SIX three polnts that rhould be cian8ed before examsnlng the behavior of concrete plates under lmpilcl loading. Frrrlly. thc high- strength concistc plate should be defined. Secondly. the dcfin~tton of Impact loadtng rhould beoutlmed. Fmally. the ohjcct#ves of the research should he dewnbed cledrly. Hngh-strength concrete IS defined as any concrete wtth eomprernve-strength over 41 MPa.
