IRJET- Comparison of Different Mixed Design Methods of Self - Compacting Concrete
0 likes4 views
1) The document compares different mix design methods for self-compacting concrete (SCC), including the Okamura, CBI, UCL, and aggregate packing methods. 2) Test results showed that the Okamura method required the least paste volume and cement and had the highest ratios of sand to mortar and coarse aggregate, making it the best performing method. 3) Compressive and flexural strength results at 7 and 28 days showed SCC designs by all methods performed better than normal concrete designs and that the Okamura method yielded the highest strengths.

Compressive strength at 7 days
Flexural Strength at 7 days
Compressive Strength at 28 days
Flexural Strength at 28 days
3. CONCLUSIONS
• Okamura Method is best among the different Self
Compacting Concrete mixed design methods as this
method consumes least past volume and cement
and utilize highest sand/mortar and coarse
aggregate
• Okamura Method requires least number of trial
mixes.
• For the same target strengths (Compressive and
Flexural) the Self Compacting Concrete mix design
methods are superior than the Ordinary Normal
mix design method

To Compare the Compressive Strength and Flexural Strength of Self- Compacting Concrete using different mixed design methods. 1. INTRODUCTION Self Compacting Concrete is a very special type of concrete which can flow and fill in to every corner of form work, even in the presence of congested reinforcement purely by its own weight and without the need of vibrating compaction. Self-Compacting Concrete (SCC) is characterized by a low yield, high deformability, and moderate viscosity necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and there after until the concrete sets. 1.
