Increased in compressive strength for higher binder volume may be due to very strong bond between aggregate and cement.For higher volume of binder quantity and lower water binder ratio, the strength of concrete cube was increased. HARDENING PROPERTIES OF SELF COMPACTING CONCRETEFig 11 Flexural Strength Vs Binder Volume Flexural strength of concrete was measured by testing of beam of size 100 mm × 100 mm × 500 mm under four point bending test using Digital Universal Testing Machine having capacity 60 tone.

Step 2: This three types of aggregates were mixed manually for obtaining a proper blend.Packing density = 1- Void content (2)To achieve maximum packing density, experiments were conducted for different proportions of aggregates. (1) and (2), the packing density of the aggregates was determined.The aggregate combination of (Fine aggregate: Coarse aggregate 10 mm maximum size: Coarse aggregate 20 mm maximum size) by volume resulted in maximum packing density (0.677), and was used in all the experiments.The mass of the cylinder along with the aggregates filled in was measured and the empty weight of the cylinder was deducted to determine the exact quantity of combined aggregates filled in the bottom container.Knowing the mass of the individual aggregate type added and the volume of the container, the void content was calculated.

Experiments were conducted to determine the packing density of different combination of aggregates The packing density of aggregates was determined experimentally, using a modified version of the test procedure described in [21].
