ABSTRACT
Two High strength concrete beams (HSCB) and four SBR-latex modified high strength reinforced concrete beams (LMHSCB) are chosen with dimension of
150 × 230 × 3300 mm. The characteristic strength of concrete used, is of 60MPa and 12 mm dia bar is used as main reinforcement along with 8 mm dia stirrups at 100mm center-to-center spacing. 53 MPa cement and 7% silica fume are used as binder. 15% of SBRlatex used in the investigation. Test beam are subjected to two different levels energy inputs. The impact responses and loads are monitored and stored during 1, 25, 50, 100, 150, 200 and upto 400 impact blows.
