Experimental and numerical studies on punching shear strength of concrete slabs containing sintered fly ash aggregates
Abstract This paper presents experimental and numerical investigations on M30 grade of concrete containing 40% of sintered fly ash aggregates (SFAs) on the punching behaviour of reinforced concrete (RC) slabs. Two 1000 x 1000 x 100 mm reinforced concrete slabs were cast and subjected to punching tes...
