?The concept of Self-Compacting
Concrete (SCC) was first proposed in
1986.
?2.Professor H. Okamura introduced this
concept.
?He was from Kochi University of
Technology, Japan.

1.Flexible Design – Can be used for any
shape.
2.Better Reinforcement – Fills gaps
around steel bars easily.
3.High Quality – Dense and uniform
concrete.
4.Smooth Finish – Looks visually
appealing.
5.Durable – Resists chemicals and gains
strength early.
? Why self-compacting
concrete..?

6.Easy Casting – Faster and
simpler pouring.
7.Efficient – Requires less labor.
8.Safer Work – Better working
conditions.
9.Eco-friendly – Reduces noise
and pollution.
10.Cost-Effective – Saves on
formwork and lasts longer.

?Normal concrete vs SCC
Aspect Normal Concrete Self-Compacting
Concrete (SCC)
? Compaction Requires external vibration for
proper compaction.
Flows and compacts under its
own weight without the need
for vibration.
? Workability Lower workability; may result in
voids if not adequately
compacted.
High flowability; easily fills
intricate formworks and densely
reinforced areas.
? Surface Finish May exhibit surface
imperfections, necessitating
additional finishing.
Produces smooth and uniform
surfaces, reducing the need for
further finishing.
? Durability Improper compaction can
lead to voids and reduced
durability.
Enhanced durability due to
uniform compaction and
reduced permeability.

Aspect Normal Concrete Self-Compacting
Concrete (SCC)
? Construction
Speed
Compaction process can slow
down construction, especially
in complex structures.
Faster placement without the
need for vibration accelerates
construction timelines.
? Labor and
Equipment
Costs
Higher labor and equipment
costs associated with the need
for mechanical vibration.
Reduction in labor and
equipment costs due to the
elimination of vibration
processes.
? Material
Costs
Generally lower material costs
as it doesn't require
specialized admixtures.
May incur higher material
costs due to the use of
superplasticizers and viscosity-
modifying agents.
? Environment Vibration equipment
contributes to noise pollution,
Quieter construction sites due
to the absence of vibration, 6/24

?Basic Properties and requirements
Key Properties of SCC
1) Filling Ability – Can flow and fill
formwork under its own weight.
2) Passing Ability – Can flow
through tight spaces without
blocking.
3) Segregation Resistance –
Remains uniform without
separation.

?Materials Used
1) Cement – OPC (43/53 grade), PPC
2) Mineral Admixtures – Fly Ash, GGBS,
Silica Fume, Metakaolin, Rice Husk Ash
3) Fine Aggregates – Well-graded river
sand, Manufactured sand
4) Coarse Aggregates – Crushed stone (10-
20 mm), Rounded aggregates preferred
5) Water – Clean potable water
6) Superplasticizers – Polycarboxylate Ether
(PCE), Naphthalene-based
7) Viscosity Modifying Agents (VMAs) –
Polysaccharides, Welan Gum, Cellulose
derivatives
8) Air-Entraining Admixtures – Synthetic
surfactants, Natural resins

? Key Points for M80 SCC Mix Design:
1.Low Water-Powder Ratio (w/p) – Typically 0.25
to 0.30 for high strength.
2.Use of Superplasticizer – To enhance workability
and self-compactability.
3.Addition of Silica Fume or Fly Ash – Improves
durability, reduces permeability.
4.Aggregate Size Limited to 12 mm – Ensures
better flow and avoids blocking in reinforcement.
5.Use of VMA (if needed) – Prevents segregation
and enhances mix stability
