Leaving the waste materials to the environment directly can cause environmental problems. Hence
the reuse of waste material has been emphasized. Partial replacement of cement by varying
percentage of marble dust powder reveals that increased waste marble dust powder ratio result in
increased workability and compressive strengths of the concrete Marble Dust Powder is settled by
sedimentation and then dumped away, which results in environmental contamination, in addition to
forming dust in summer and threatening both agriculture and public wellness. In this research
work, Marble Dust Powder has replaced the (OPC & PPC) cement accordingly in the reach of
0%,10%, 20%, by weight of M-40 grade concrete. Concrete mixtures were developed, tested and
compared in terms of compressive strength to the conventional concrete. The purpose of the
investigation is to analyze the behavior of concrete while replacing the Marble Dust Powder with
Different proportions in concrete.

1. High strength concrete is a type of high performance concrete generally with a specified strength
of 6000 psi (40MPa) or greater.
2. It is generally obtained by maintaining lower w/c or w/b ratio, addition of mineral admixtures,
addition of superplasticizers.
3. The main reasons to use high strength concrete is
i. Reduce the amount of steel
ii. Reduce dead load
iii. Reduce space occupied by columns
iv. Increase rental space
v. To use concrete service at early age

5. Department of civil engineering Bangalore institute of technology 5
4. when marble powder is substituted as binder with cement the strength will be higher at lower
replacements up to 10%.
5. Marble is a metamorphic rock resulting from the transformation of a pure limestone.
6. Auramix 450 is a high performance superplasticizer intended for applications where high water
reduction and long workability retention are required and it has been developed for use in:
i. Self-compacting concrete
ii. Pumped concrete
iii. Concrete requiring long workability retention
iv. High performance concrete.

1. To study the compressive strength of concrete on 7th and 28th day.
2. To study the rate of increase in strength of concrete.
3. To study the functions of admixtures (minerals, plasticizers)
4. To achieve a concrete mix of strength greater than 40 N/mm².
5. To study the strength of the concrete. which can be increased by using marble dust.
6. As marble powder acts like a pollutant so by partially replacing cement with marble powder there
will be reduction in cement.

Study on Effect of
Mineral Admixtures
in High Performance
Concrete.
In high strength concrete with a
very low water/binder ratio, hydration stops
within the concrete long before 28 days due
to lack of water or when the partial pressure
of water vapour within the pores has
reached the 80% limit below which
hydration is slowed down very significantly.

MIX DESIGN
Target strength : M40
Type of cement – OPC 53 grade confirming to IS 456:2000
Type of mineral admixture : Marble dust
Maximum nominal size of coarse aggregate : 20mm
Minimum cement content : 300kg/m3
Workability : 75mm slump
Maximum water cement ratio : 0.50
Type of exposure condition : Moderate
Chemical admixture : Aura mix 450
Characteristic compressive strength at 28 day : _____

20. Department of civil engineering Bangalore institute of technology 20
Target strength for mix proportioning
f’ck = fck + 1.65 S
Where,
f’ck = Target average compressive strength at 28 days,
fck = Characteristic compressive strength at 28 days,
S= Standard deviation from Table 1 standard deviation, s = 5 N/mm2,
Therefore, target strength = 40 + 1.65 x 5 = 48.25 N/mm2
Selection of water cement ratio : from Table 5 of IS:456-2000
Maximum water cement ratio = 0.50 Hence ok
Selection of water content :
From Table-2 of IS:456-2000
Maximum water content = 186 litres (for 25mm – 50mm slump range and for 20 mm aggregates)

21. Department of civil engineering Bangalore institute of technology 21
Calculation of cement content :
Water-cement ratio = 0.5
Cement content = maximum water content / water-cement ratio = 186 / 0.5 = 372 kg/m3 > 300 kg/m3
Hence Ok.
Proportion of volume of coarse aggregate and fine aggregate:
Fine aggregate = Zone I
Coarse aggregate = 20mm (down size) W/C = 0.5
For every decrease of 0.05 w/c, CA raised by 0.01 for 0.5 w/c
Volume of coarse aggregate = 0.6+0.01 = 0.61
Volume of fine aggregate= 1-0.61 = 0.39

0.117m3
c. Volume of water = (Mass of water/specific gravity of water) x (1/1000) = 186/1 x 1/1000 = 0.186m3
d. Volume of all in aggregates = [a-(b+c)] = [1-(0.117+0.186)] = = 0.697 m3
e. Mass of coarse aggregate = d x Volume of coarse aggregate x Specific gravity of coarse aggregate x 1000 =
0.697 x 0.610 x 2.71 x 1000 = 1130.95 kg

COMPRESSIVE STRENGTH OF CONCRETE:
Compressive strength is the ability of material or structure to carry the loads on its surface without any crack or
deflection. A material under compression tends to reduce the size, while in tension, size elongates.

Compressive strength test results:
Compressive strength test is done as Per IS 516-1959. The test is conducted on Compression testing
machine of capacity 2000 KN. Mechanical behavior of concrete was studied for M40 grade of cubes
were casted and cured for 7 and 28days. Compressive strength of concrete is tested on cube at
different percentage of Marble dust powder content in concrete. The strength of concrete has been
tested on cube at 7 days curing and 28 days. And the results obtained are reported in table 1 & also
shown in graph 1. With replacement of marble dust powder in % age, in concrete 7 days test has been
conducted to check the gain in initial strength of concrete & 28 days test gives the data of final
strength of concrete at 28 days curing. Compression testing machine is used for testing the
compressive strength test on concrete.

1. The Compressive strength of Concrete increases up to 10% replacement of cement by marble dust
powder and further increasing of percentage of marble dust powder leads to decrease in compressive
strength of concrete.
2. It is concluded that the marble dust powder can be used as a replacement material of cement, and
10% replacement of cement with marble dust powder gives an excellent result in strength, as
compared to the normal concrete.
3. Use of these waste material leads to sustainable development in construction industry.
4. To save the environment, marble dust powder may be used as better partial substitute as a
replacement of cement in concrete.
