4. CONCEPT OF
SELF COMPACTING CONCRETE [SCC]
•MakingConcretestructurewithoutvibrationisthebasic
conceptofSCC,Example–Placementofconcreteunder
waterbyuseoftermiewithoutvibration.
•Placingconcretefortallcolumnsintheliftof5-6meters
withoutvibration.

5. •Placing concrete with horizontal flow of 10 mtr. Without
vibration.
•The concept was designed initially in Japan at University of
Tokyo in 1980 but was further developed in 1990 and
substantial use is done after year 2000.
•European Federation of Natural Trade Association
representing product and application of specialist building
products (EFNARC) is the main European Federation using
developed SCC.

8. ADVANTAGES OF SCC

9. ADVANTAGES OF
SELF COMPACTING CONCRETE [SCC]
•Faster construction
•Reduction in Site Manpower
•Better surface finish
•Easier placement
•Improved durability
•Greater freedom in designing concrete sections
•Reduced noise level
•Safer working environment

10. There are 3 ways in which SCC can be made
a)Powder Type
b)VMA Type
c)Combine Type
FORMS OF SCC MIXES
