4.  Concrete is a second most consumed substance on earth
after water. Cement production is growing by 2.5%
annually and is expected to rise from 2.55 billion tons
in 2006 to 3.7-4.4 billion tons by 2050.
 A single industry accounts for around 7% of global
carbon dioxide emission. The production of cement
releases greenhouse gas emissions both directly and
indirectly: the heating of limestone releases Co2
directly, while the burning of fossil fuels to heat the kiln
indirectly results in Co2 emissions.
 Use of waste glass powder, Fly ash, GGBS in concrete
also have influence on the mechanical properties of
concrete.

5.  The objective of the research is to know the percentage to
which glass powder, fly ash and GGBS can replace the
cement in concrete.
 To check effect on workability, strength, durability of
concrete using the waste glass powder, Fly ash and GGBS as
a partial substitute for cement.
 To produce the concrete which will protect the environment,
 To produce the good concrete, which will have less
permeability as compare to normal mix.

12. METHODOLOGY
1) Workability Test - IS 7320-1974
This test is conducted on fresh concrete to measure the workability according to IS:
7320-1974.
2) Compressive Strength Test - IS 516:1959
A cube compression test performed on standard cubes of size 150mm x 150mm x 150
mm after 3 days, 7 days and 28 days. The compressive strength of specimen is calculated by the
following formula:
fcu = Pc /A
where Pc = Failure load in compression, N
A = Loaded area of cube, mm2
fcu = Compressive strength, N/mm2
3) Split Tensile strength Test – IS 5816:1999
 The split tensile test conducted on cylinders of 150 mm dia. and 300 mm height. The load
was applied at a uniform rate till the specimen failed by a fracture across vertical diameter.
 The split tensile strength of cylinder is calculated by the following formula:
fcys = 2Psp / π D L
Where, fcys = Split tensile strength, Mpa
Psp = Load at failure, N
L = Length of cylinder, mm
D = Dia. Of cylinder, mm

13. 4) Flexural Strength Test – IS 516:1959
 In flexure test, the Standard beam specimen of size (100mm x 100mm x 500mm) will be
supported symmetrically over a span of 400mm.
 The flexural strength was determined by the formula:
fcr = Pf L / bd2 or 3Pf a / bd2
Where,
fcr = Flexural strength, MPa
Pf = Central load through two point loading system, N
L = Span of beam, mm
b = Width of beam, mm
d = Depth of beam, mm
a = Distance between line of fracture to the nearest
support, mm.
5) Pull out Test – IS 2770 (Part I)-1967
Pull out load of each specimen is find out with the help of Universal Testing Machine.
Bond Stress is calculated by following formula:
Ʈ= F/ (L x S)
Where, Ʈ = Bond Stress in MPa
F = Applied pulling load in KN
S = Perimeter of rebar
L = Embedded length of rebar= 130 mm

14. 6) Water Absorption test :
Water absorption is calculated by using following formula:
% Water Absorption = (A – B)/B X 100
Where,
A = Wet mass of unit in Kg
B =Dry mass of unit in Kg
7) Rebound hammer test – IS 13311-2 (1992)
Rebound hammer test used to find out the compressive strength of concrete
by using rebound hammer as per IS: 13311 (Part II)-1992.

15. 8) Ultrasonic Pulse Velocity Test – IS 13311-I (1992)
This test is done to assess the quality of concrete by ultrasonic pulse
velocity method as per IS: 13311 (Part I)-1992. Method consists of
measuring the time of travel of an ultrasonic pulse passing through the
concrete being tested.
Comparatively higher velocity is obtained when concrete quality is
good in terms of density, uniformity, homogeneity etc.
9) Rapid Chloride Permeability Test – ASTM C1202-1997
This test is performed to know the chloride ion penetration in
concrete and thus its final effect on reinforcement in concrete.

 As glass content increases, cement paste available is less for providing lubricating effect
per unit surface area of aggregate. Therefore workability of concrete decreases.

21. Graph 5: Comparative Pull out strength of concrete with cement replacement with glass

 The pull-out strength increases with the percentage increase of glass powder in concrete. An
increase of 8.19%, 13.42% and 19.90% strength was observed for 5%, 10% and 15%
replacement respectively.
 This increase in strength up to 15% replacement of cement by glass powder may be due to the
pozzolanic reaction of glass powder due to high silica content. Also it effectively fills the
voids and gives dense concrete microstructures

22. 1) As the Percentage of glass powder in concrete increases workability of concrete
decreases. A decrease of 3.23%, 12.91%, 19.36% workability was observed for
5%, 10% and 15% replacement respectively. As there is a reduction in fineness
modulus of cementitious material, cement paste available is less for lubricating
effect per unit surface area of aggregate. Therefore as glass content increases, (i.e.
cement content decreased) workability decreases.
2) The replacement of cement by glass powder in concrete increases the compressive
strength of concrete. For 28 days increase of 4.50 %, 14.53% and 25.70% strength
can be achieved when 5%, 10% and 15% cement was replaced by glass powder in
concrete. This increase in strength up to 15% replacement of cement by glass
powder may be due to the pozzolanic reaction of glass powder due to high silica
content. Also it effectively fills the voids and gives dense concrete
microstructures,
3) The replacement of cement by glass powder in concrete also increases the split
tensile strength of concrete. Increase of 2.82 %, 7.05 % and 16.47 % strength can
be achieved when 5%,10% and 15% cement was replaced by glass powder in
concrete when water/ cement ratio was maintained constant.
4) The flexural strength of glass powder concrete increases by 6.43%, 14..85% and
19.80% at the replacement of 5%, 10% and 15% respectively when compare with
conventional mix.
