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.
