INTEGRATED PLAIN AND SLURRY INFILTRATED FIBRE CONCRETE (IP-SIFCON) COMPOSITE BEAMS

Composite beams (IP-SIFCON) were composed of two layers; a bottom SIFCON layer and an upper layer manufactured of plain cement paste. Beams made totally with SIFCON were also investigated for comparison. The effects of the SIFCON layer thickness on the flexural strength and energy absorption of composite beams were reported. The IPSIFCON beams exhibited a distinctive deflection hardening behaviour and performed comparatively with total SIFCON beams. The studies indicate that, compared with normal concrete beams, the IP-SIFCON composite beams have significantly improved flexural strength and energy absorption capacity.
