Abstract
This paper sheds light on the behavior of reinforced concrete RC spliced one-way slab OWS in the case of using four types of concrete in the splice region in addition to the non-spliced specimen. Five specimens have been used, one cast as a monolithic unit for comparative and four consisting of three precast members and two splice regions with (normal concrete NC, high strength concrete HSC, slurry infiltrated fiber reinforced concrete SIFCON, and reactive powder concrete RPC). The whole dimensions of specimens are 2130mm length, 600mm width, and 100mm thickness. The parameters that have been studied which first flexural cracks, ultimate load, max deflection, longitudinal concrete strain and failure mode in addition to calculating a new index called ductility index which represented the capacity of ductility after failure, in which proportions to the deflection at ultimate load and flexural cracking load. The results from the investigation test shows that in the case of using RPC and SIFCON in the splice region, there is a convergence in increasing value of ultimate load and deflection. While no improvement in specimens' behavior with NC and HSC in the splice region.
