This paper compared the rheological properties and compressive strengths of self-compacting\nconcrete (SCC) and conventional cement concrete. The flowability and segregation resistance of\nfreshly mixed concrete specimens were examined by the V-funnel apparatus, while the characteristics\nof passing ability were investigated with the L-box apparatus. Cylindrical concrete specimens\nof 100 mm diameter Ã?â?? 200 mm length were investigated for compressive strength. The\nrheological properties of SCC are incomparable with those of the conventional concrete due to\ntheir diverse testing methods and characteristics of individual flow. The compressive strength results\nof hardened concrete showed that SCC gained strength slowly compared to the conventional\ncement concrete due to the presence of admixtures and its 28 days strength was lower than conventional\ncement concrete, but SCC eventually had potentials of higher strength beyond 90 days.\nFinally, the effect of water-cement ratio on the plastic properties of self-compacting concrete was\nquite negligible compared to conventional concrete.
