3. Introduction to
Self Compacting Concr

4. INTRODUCTION
 SCC, was first introduced in the late 1986’s by
Japanese researchers
 Also known as
“ SELF - CONSOLIDATING CONCRE TE ’’
& “ SUPER WORKABLE CONCRETE ’’
 Self-compacting concrete (SCC) is an innovative
concrete
 It is able to flow under its own weight, completely filling
formwork and achieving full compaction

5. Why SCC Is Required ?

6. REQUIREMENTS
 · Faster construction
 · Reduction in site manpower
 · Better surface finishes
 · Easier placing
 · Improved durability
 · Greater freedom in design
 · Reduced noise levels, absence of vibration

7. HOW SELF COMPACTION
IS ACHIVED

8. ACHIVEMENT OF SCC
 Reduce volume of ratio of Aggregate to the
cementations materials
 Increase the Water Cement ratio
 Grading Coarse Aggregate & Fine Aggregate Content
 Use Powdered material or Admixtures to modifying
viscosity
 Use super plasticizers for high mobility

9. ACHIVEMENT OF SCC

10. TEST

11. WHERE SCC IS USED

12. U-S-E-S
 In Congested Reinforcement

13. SCC FOR COVERING REINFORCEMENT
Regular Concrete column
exhibits poor
compaction

14. REGULAR HPC BEAM POOR CONSOLIDATION

15. SMOOTH SURFACE FINISH

16. TEXURE SURPRISE WITH SCC

17. LIMITATIONS IN SCC
• Slightly Higher Creep due to paste
• Skilled worker in production
• Formwork
• Casting time is more
• Costing Factor

18. SOME EXAMPLES OF SCC STRUCTURE

19. SOME EXAMPLES OF SCC STRUCTURE
•Year of built : 2009
•SCC volume : 250000 cubic meter
•Location: Dubai
•Project Highlights:
- Highest amount of SCC
-Tallest building
Case Example : Burj Khalifa

20. SOME EXAMPLES OF SCC STRUCTURE

21. SOME EXAMPLES OF SCC STRUCTURE

22. CONCLUSION
22
 SCC with high workability, proper strength, and
adequate durability can be produced using locally
available materials.
 Attention must be paid to formwork, segregation, and
shrinkage.
