The flowability and segregation resistance of freshly mixed concrete specimens were examined by the V-funnel apparatus, while the characteristics of passing ability were investigated with the L-box apparatus. Cylindrical concrete specimens of 100 mm diameter × 200 mm length were investigated for compressive strength. (2015) Evaluation of Fresh and Hardened Properties of Self-Compacting Concrete. Then after it was increased and flexural strength of concrete reach up to 4.89 MPa.This paper compared the rheological properties and compressive strengths of self-compacting concrete (SCC) and conventional cement concrete. The compressive strength for 450 kg/m3 binder and 0.36 W/B ratio was observed around 62.65 MPa.The compressive strength was decreased as binder quantity increased up to 550 kg/m3.10 indicates a good correlation between the compressive strength and W/B ratio.

Flexural strength of beam was decreased as compressive strength of concrete decreased up to 550 kg/m3 volume of binder. Aggregates with higher packing density result in lesser void content, in turn minimising the volume of paste to fil up the voids. Packing density of aggregates is an indicator of the voids content.Step 3: The mixed aggregates were poured into bucket without any compaction.Step 4: Then, mixed aggregates were filled in a cylindrical container of known volume. PROPORTIONS OF AGGREGATES WITH CORRESPONDING EXPERIMENTAL PACKING DENSITYmore than 10 times the diameter of the maximum size of aggregates used to eliminate the wall effect.
