2.  Definition of Lightweight Concrete .
 Types and classification of Lightweight
Concrete
 Advantages of Lightweight Concrete
 Durability of Lightweight Concrete
 Mix design of Lightweight Concrete
 Application of Lightweight Concrete
 Test on light weight concrete

3.  LIGHTWEIGHT CONCRETE
It may be defined as the concrete of
substantially lower unit weight than that
made from gravel or crushed stone.
. It is made with a lightweight coarse
aggregate and sometimes a portion or entire
fine aggregates may be lightweight instead
of normal aggregates.

4.  Lightweight Aggregate Concrete
 Aerated Concrete
 No Fines Concrete
 Low density concrete
 Moderate strength concrete
 Structural concrete

5.  Reduced dead load of wet concrete allows
longer span to be poured un-propped.
 Reduction of dead load, faster building
rates and lower haulage and handling costs.
 The use of LWC has sometimes made its
possible to proceed with the design which
otherwise would have been abandoned
because of excessive weight.

6.  In frame structures, considerable savings in
cost can be brought about by using LWC for
the construction floors, partition and
external cladding.
 Most building materials such as clay bricks
the haulage load is limited not by volume
but by weight.
 With suitable design containers much
larger volumes of LWC can haul
economically.

7.  Screeds and thickening for general
purposes especially when such screeds or
thickening and weight to floors roofs and
other structural members.
 Screeds and walls where timber has to be
attached by nailing.
 Casting structural steel to protect its
against fire and corrosion or as a covering
for architectural purposes.
 Heat insulation on roofs.
 Insulating water pipes.
 Construction of partition walls and panel
walls in frame structures.

8.  Durability is defined ass the ability of a
material to withstand the effect of its
environment.
 Chemical attack is as aggregate ground-
water particularly sulfate, polluted air, and
spillage of reactive liquids LWC has no special
resistant to these agencies:
 it is generally move porous than the ordinary
Portland cement.
 A chemical aspects of durability is the
stability of the material itself, particularly at
the presence of moisture.

9. Light weight concrete finds its use generally
in situations like:
 Decks of long span bridges.
 Fire and corrosion protection.
 Heat insulation on roofs.
 Insulation of water pipes.
 Filling for floor and roof slabs.
 Construction of partition walls and panel
walls in framed structures.

10. 1. Cement
2. Fine aggregates
3. Coarse aggregates
4. Water
5. Expanded polystyrene sphere ball

11. Step 1. Choice of concrete slump
Step 2. Choice of maximum aggregate size
Step 3. Estimation of maximum water and air
content
Step 4. Water cement ratio
Step 5. Calculation of the amount of cement
Step 6. Estimation of coarse aggregate
Step 7. Calculation of fine aggregate

12.  Compressive strength on cubes 7 days and
21 days.
 Split tensile strength on cylinder for 7 and
21 days.
 Slump cone test.

16.  The compression and split tensile strength of
concrete was determined by varying percentage
of expanded polystyrene sphere balls (eps) of
6%,45%and 65%.
 The light weight concrete having less strength
compare to nominal concrete but is economical ,
durable .
 The light weight concrete can be used in building
construction like partition walls in theatre for
sound proof and it can used for flooring, wooden
roofs for filling gaps (only eps square boxes)
 Etc…
