 India is the fast developing country having concrete
construction trend to make different structure, as it is easily
available and the workable by unskilled labors.
 Concrete is being used for all important structures like dams,
towers, water tanks, houses, roadways, and railway sleepers
etc.
 Long-term behavior of structures has become vital to the
economies of all nations. Concrete has been the major
instrument for providing stable and reliable Infrastructure [3].

 At the same time, Environment prevention is pin point for the
civil industry because of cement production. sustainable
development is in demand, because of global warming and
CO2 emission.
 Rapid growth of advanced technology in various industrial
sector are also facing waste disposal problem and
environmental pollution. In recent research scenario of civil
industry, the worldwide total production of Portland cement is
about 550 million tones, which is widely used in the
production of concrete.
 This production emits the large volumes of CO2 estimates as
high as 5% of total global man made CO2 emissions, thus its
production is responsible factor for global warming and
climate-change. [2]

 As a solution of better performance of structural materials
with environment prevention, steel making industry waste
powder giving better enhanced strength of concrete. [2, 8-
10]
 This research work introducing the acceptable partial
replacement of the steel waste powder in place of ordinary
Portland cement to minimize environmental pollution due to
cement production considering waste disposal solution.
 In the concrete making process, pure steel making waste
used in powder form having compositions of SiO2, Al2O3,
Fe2O3, CaO, MgO, SO3, Sulphide, Na2O3, K2O, Cl and MnO.
Combined effect of these all compositions greatly affected on
the mechanical properties of concrete containing this waste
powder. [11,12]

 In this research work, the effect of steel industry waste in a
powder form is examined to produce concrete.
 To achieve main objectives of the study, waste was collected
from steel industry and grinded in ball mill to produce
Portland cement sized powder.
 The waste powder was examined for chemical and mechanical
investigation with cement replacement.
 Optimum cement replacement was done with the waste
material in a powder form to produce desirable concrete
solving the problem of waste disposal.

 According to the current
recommendations of ACI
Committee 544, the test is
to be carried out by
dropping a hammer
weighing 44.7 N from a
height of 457 mm
repeatedly on a 63.5 mm-
diameter hardened steel
ball that is placed on the
top of the center of a 150
63.5 mm cylindrical
concrete specimen (disc).
The steel ball is free to
move vertically within a
63.5 mm cylindrical sleeve.

29.  Concrete with the optimum waste powder replacement
in place of cement experiences a higher rate of flexural
strength because of homogeneity in the equal
distribution of hydration process in concrete.
 Because of enhanced mechanical properties, it is
advisable to use this concept to produce concrete from
waste material in powder form in place of cement in
the construction industry.
 The fresh parameters like slump is good for concrete
containing waste compare to conventional concrete
even after 90 minutes so it is beneficial to use this
concrete as Ready mix concrete.

30.  The impact energy is absorption of this concrete is
better that it can be use for the important
structures which can be safeguard against impact
or blast.
 The production of cement generates one ton of
CO2 in environment for each ton of cement, so it is
advisable to use waste as cement replacement. It
saves the environment as well as the natural
recourses.

31.  The waste material reduces the cost compare to
conventional concrete as cement replacement is
done by waste powder which is cheap and
economical compare to cement as the cost of
cement is 5times higher than the waste.
 The concept of waste utilization as cement
replacement is economical, feasible as it improves
the strengths and beneficial to environment as it
reduce CO2 emission by minimizing cement
consumption which makes it a sustainable solution
for the construction industry.
