Introduction to Self Compacting Concrete
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
Why SCC Is Required ?
REQUIREMENTS · Faster construction · Reduction in site manpower · Better surface finishes · Easier placing · Improved durability · Greater freedom in design · Reduced noise levels, absence of vibration
HOW SELF COMPACTION
IS ACHIVED?
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
ACHIVEMENT OF SCC
TEST
WHERE SCC IS USED ?
U-S-E-S In Congested Reinforcement
SCC FOR COVERING REINFORCEMENT
Regular Concrete columnexhibits poorcompaction
REGULAR HPC BEAM POOR CONSOLIDATION
SMOOTH SURFACE FINISH
TEXURE SURPRISE WITH SCC
LIMITATIONS IN SCC
• Slightly Higher Creep due to paste• Skilled worker in production• Formwork• Casting time is more• Costing Factor
Formwork
SOME EXAMPLES OF SCC STRUCTURE
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

CONCLUSION

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.
