Abstract

Self compacting concrete (SCC) is a new, innovative technology which represents one of the most significant advances in concrete technology during the last two decades. The use of SCC for the production of hollow core slabs (HCS) is proposed to allow for placing shear reinforcement in deep HCS. However, many researchers have expressed concern that SCC could negatively affect the hardened properties such reductions in the modulus of elasticity as well as shear strength and bond between concrete and steel strands. This paper presents development work on the manufacture of HCS using SCC. Preliminary results of short-term flexure testing of full-scale HCS members made using SCC and conventional dry cast concrete (DCC) are presented and discussed.
