2. WHAT IS MEAN BY CONCRETE ?
“Concrete is a composite construction material
composed primarily of aggregate, cement, and water”.
 The aggregate is generally a coarse gravel or crushed
rocks such as limestone, or granite, along with a fine
aggregate such as sand.
 Concrete has relatively high compressive strength, but
much lower tensile strength. 2

3. SELF COMPACTING CONCRETE :
“Self compacting Concrete is highly engineered
concrete with much higher fluidity without
segregation and is capable of filling every corner
of form work under its self weight only”.
 It eliminates the need of vibration either internal or
external for its compaction.
 It reduces the deterioration of concrete quality
due to lack of skilled labors.
3

4. INTRODUCTION TO SELF COMPACTING CONCRETE:
 It was first devloped in japan in late 80’s to increase the
concrete quality.
 It is an innovative concrete which flows under its own
weight.
 Construction material consists of cement and Aggregates
only.
 It eliminates the vibration either internal or external.

5. TYPES OF SELF COMPACTING CONCRETE
 Powder type of self compacting concrete.
 Viscosity agent type self compacting concrete.
 combination type self compacting concrete.

6. ADVANTAGES OF SCC
 Beneficial in structures where casting are difficult due to
congested reinforcement.
 shows good filling ability.
 very well suited for special and technically demanding
structures such as tunnel linings.
 Reduction in wear and tear of forms, therefore, it extends
the service life of forms.
 Reduction in the number of worker.

8. DISADVANTAGES OF SCC:
 The production of SCC places more stringent requirements on
the selection of materials in comparison with conventional
concrete.
 An uncontrolled variation of even 1% moisture content in the
fine aggregate will have a much bigger impact on the. Property
of SCC.
 The development of a SCC requires a large number of a trial
batches.
8

9. INGRADIENTS USED:
Cement:-
 Generally Portland cement is used.
Aggregates:-
 Aggregate of size 10 mm is desirable for structures
having congested reinforcement.
 Aggregates should be cubical or rounded.
 Particles smaller than 0.125mm i.e. 125 micron size are
considered as FINES which contribute to the
powder content.

10. Mixing water: -
 Ordinary potable water of normally pH 7 is used for
mixing and curing the concrete specimen.
Admixtures for SCC:-
There are two types of admixture normally added in
scc.
 chemical admixtures
 Mineral admixtures
10

11.  Chemical Admixtures:-
These are essential component of scc used to provide
necessary workability, freezing resistance.
e.g; Glenium TM SKY 784
Mineral Admixtures:-
These improves quality and durability of SCC.
e.g; fly ash, red mud & foundry sand.

12. HOW TO CHECK SUITABILITY?
There are many new tests: V-funnel, L-box, U-box,, Slump Flow
and J-ring.
While several of these may be used in mix development, only
the some will find site use.
Slump flow test:
 It used to find flowing Ability
of concrete in absence of
obstructions.
 It was first developed in japan.
 The diameter of concrete circle
is the measure of filling ability
of concrete.

14. WHAT IS RED MUD?
 Red mud is the iron rich residue from the digestion of bauxite.
 It is one of the major solid waste coming from Bayer process
of alumina production.
 It is a finely powdered mud. It adversely effects the air, land
& water environment of surrounding area.
 At present about 60 million tones of red mud is generated
annually worldwide which is not being disposed or recycled
satisfactorily.

15. WHAT IS FOUNDRY SAND?
 Foundry sand consists of clean,
uniformly sized, high quality
silica sand that is bonded to
form molds for ferrous and
nonferrous metal castings.
 Angle of shear resistance of
foundary sand is in the range of 33 to 40 degree as
compared to conventional sand.
 The automotive industry and its parts suppliers are the
major generators of foundry sand. 15

16. NEED FOR SCC
 Foundry sand and red mud has pozzolonic properties hence
increases the binding properties .
 Red mud has higher compressive strength ,therefore it can be
used to prepare lighter concrete.
 Foundry waste sand basically contains uniformly sized, and
which having one or more organic binder
 It gives better strength at the same time it reduces the cost
problems.
16

17.  Foundry waste sand has low absorption and non plastic nature.
 shear resistance of foundary sand is in the range of 33 to 40
degree as compared to conventional sand.
17

18. WHAT’S NEW?
 Industrial waste (i.e.: red mud ,foundry waste sand) is
used for preparation of SCC.
 Instead of cement this industrial waste are used in
different percentage.
Red mud:1%, 2%, 3% upto 8%.
foundry waste sand: 2%, 4% upto 10%.
Aim of experimentation:
The main aim of this experimentation is to find out the
effect of addition of red mud, which is a waste product
from the aluminium industries, and foundry waste sand,
which is a waste product from foundry, on the properties
of self compacting concrete containing two admixtures.
18

19. MATERIAL USED:
 The specific gravity of sand was found to be 2.55 and was
Zone II sand.
 The specific gravity of coarse aggregates used was found
to be 2.61.
 The coarse aggregates were 12mm and down size.
 A water/binder ratio 0.31.
 The flyash/cement ratio used was 1:3.5.
 In addition to this red mud and foundry sand is used.
