Abstract

In terms of the importance of implementing mega constructions in 4-G citiesthat need slabs capable to resist punching shear strength, this research was initiated in order to investigate the resistance of fiber reinforced geo-polymer concrete “FRGPC” slabs with opening to punching at slab-column connection, in reference to Ordinary Portland Cement Concrete “OPCC” slabs. Primarily, literature in the field of FRGPC slabs was reviewed.An experimental work was achieved in the Faculty of Engineering, Fayoum University's Concrete Research and Material Properties Laboratory, whereFRGPC and OPCC cubes, cylinders and slabs (i.e. with and without openings)with different fiber ratios were cast to investigate their mechanical properties and slabs punching shear.Measurements were undertaken; analyzed and graphs so as tables were produced.Finally, conclusions were deduced and recommendations were suggested. The results highlighted that FRGPC (i.e. with 1.5% fiber) improved the mechanical properties, in reference to OPCC. In addition, he results flagged-out that FRGPC slabs without opening (i.e. with 1.5% fiber) enhanced the punching strength in reference to slabs with opening.
