Abstract

Statement of the problem. An experimental investigation of impact strength of ternary blended cement concrete slab with steel fiber under impact loading was carried out. The amount of replacement of binder with Fly ash varies from 10 to 30 % in step of 10 %, glass powder from 20 to 40 % in step of 10 % and fiber volume fraction from 0.75 to 2.25 % in step of 0.75 %. Parametric performance of ten 600 × 600 mm, 60 mm thick reinforced concrete slabs was evaluated. The impact test on the slab was conducted by dropping a steel ball from a height of 457 mm under impact setup. The parameters like failure mode, the impact energy of first crack and ultimate crack failure, ductility index, failure pattern, ultimate crack resistance, crack resistance ratio were investigated when subjected to impact load. Results. The test results reported that the slab specimen S7 shows better performance in strength.
