This document presents a study on partially replacing cement with sugarcane bagasse ash, rice husk ash, and stone dust in concrete. Testing showed that replacing cement with 2% of these materials increased the 7-day compressive strength of concrete cubes to 40.8 MPa compared to 29.4 MPa for normal concrete. The 28-day split tensile strength of cylinders peaked at 3.13 MPa with a 2% replacement, compared to 2.86 MPa for normal concrete. Overall, small replacements of up to 4% improved strengths due to chemical reactions between the admixtures and cement hydration products, but larger replacements weakened concrete.

ABSTRACT
A Large quantities of waste materials and by-products are generated from
manufacturing processes, service industries and municipal solid wastes, etc.
As a result, solid waste management has become one of the major
environmental concerns in the world. With the increasing awareness about the
environment, scarcity of land-fill space and due to its ever increasing cost,
waste materials and by-products utilization has become an attractive
alternative to disposal. High consumption of natural sources, high amount
production of industrial wastes and environmental pollution require obtaining
new solutions for a sustainable development.
Ordinary Portland cement is recognized as a major construction material
throughout the world. Significant research has been going-on in various parts
of the world on the subject. Some waste materials and by-products have
established their credentials in their usage in cement-based materials and for
others research is in progress for exploring the potential applications. This
waste, utilization would not only be economical, but may also result in foreign
exchange earnings and environmental pollution control. Industrial wastes,
such fly ash and silica fume are being used as supplementary cement
replacement materials. Currently, there has been an attempt to utilize some
amount of bagasse ash, rice husk ash and stone dust.

1. INTRODUCTION
1.1. GENERAL
In civil engineering, theoretical knowledge is an application for practical knowledge
which is quite different in any field. In civil engineering aspects now-a-days the
construction of buildings, industries, residential complexes etc. are more essential.
These are included with high expensive of cost, to built up. For that, the no. of
techniques are implemented to reduce the cost of construction in all aspects.
Economically it is very useful for construction purpose.
Replacement of a material with another material is one type of technique which is
mostly using in now-a-days to reduce the cost. Replacing of cement (or) coarse
aggregates (or) fine aggregates with other materials which is made to be an
economical.
1.2. NEED OF THE PRESENT PROJECT
Cement is the most costlier and energy intensive component of concrete. The unit cost
of concrete can be reduced by partial replacement of cement with SCBA, RHA & SD.
Concrete making with conventional material is becoming costlier day by day. More
over concrete suffers little resistance to cracking. These problems may overcome by
inclusion of these admixtures into concrete.
1.3. MATERIALS USED
1.3.1. Cement
The most common cement used is ordinary Portland cement. Out of the total
production, ordinary Portland cement accounts for about 80-90 percent. Many tests
were conducted to cement (53 Grade) some of them are consistency tests, setting
tests, soundness tests, etc.
1.3.2 Fine Aggregate
Locally available free of debris and nearby river bed sand from ferri river is used as
fine aggregate. The sand particles should also pack to give minimum void ratio,
higher voids content leads to requirement of more mixing water. In the present study
the sand conforms to zone II as per the Indian standards.
1.3.3 Coarse Aggregate
The crushed aggregates used were 20mm nominal maximum size and are tested as per
Indian standards and results are within the permissible limit.
1.3.4 Water
Water available in the college campus conforming to the requirements of water for
concreting and curing as per IS: 456-2000.
2. INTRODUCTION OF ADMIXTURES
From these by-products in concrete production brings a positive effects to the
environment which reduces waste disposals. Since we reduce the cement production
also. AGRO INDUSTRIAL MINERAL ADMIXTURES is a factory which reduces
the emissions generated by the disposal of all by-products.

http://www.iaeme.com/IJCIET/index.asp 165 editor@iaeme.com
Due to these admixtures there is a change in concrete in both physical and
chemical conditions. The physical effects are the mixture which depends on size,
shape, and textures of particle. The chemical effects are capability of providing
aluminous compounds which react chemically in the presence of water like calcium
hydroxide etc., the two scientists namely GOLDMAN &BENTUR Said that by
mixture of these admixtures there is a physical effects are more than the chemical
effects.
The admixtures which are used for the replacement of cement are as follows.
• SUGARCANE BAGASSE ASH
• RICE HUSK ASH
• STONE DUST (or) QUARRY DUST

6.8.1 COMPRESSIVE STRENGTH TEST
The compressive strength is evaluated by placing a cubical specimen between the
loading surfaces of compression testing machine of capacity 2000 KN, in such a way
that the smooth surface receives the directly and the load is applied until failure of the
cube, along the sides of the cube. The compressive strength is determined by the ratio
of failure load to the cross sectional area of the specimen.
The compressive strength of concrete has been evaluated by testing four cubes of
size 15 cm x 15 cm x 15 cm, the testing procedure is shown in fig. (p) & fig. (q).
The results are tabulated in table-7 and the graph is drawn, shown in graph-1.

6.8.2. SPLIT TENSILE STRENGTH
The Split tensile strength of concrete have been evaluated by testing the cylindrical
specimens of size 15 cm diameter and 30 cm length. The testing procedure is shown
in fig. (r) & fig. (s).
The split tensile tests are done by placing a cylindrical specimen horizontally
between the loading surface a compression testing machine and the load is applied
until failure of cylinder, along the vertical. The split tensile test values determined for
different specimens from tests are presented in table-8. The result obtained from the
experimental work for 7 & 28 days are shown in the charts as given below.

The Compressive and Tensile strength of cubes & cylinders are increases at 6% which
includes 2% of each admixture, when compared to normal mix &other mix
proportions.
8. CONCLUSIONS
• It has been observed that by the incorporation of SCBA, RHA & SD as a partial
replacement to cement in plain concrete, increases workability when compared to
workability with reference to concrete made without admixtures.
• The mix proportion of 6% replacement of cement with SCBA (2%), RHA (2%) & SD
(2%) showed good properties like Compressive and Tensile strength.
• It has been observed that cement replacement using SCBA, RHA & SD can go up to
8% safely through strength values are less compared to 2% replacement of cement
and is most economically feasible.
9. SCOPE FOR FURTHER INVESTIGATION
• Experiments can be encouraged with different proportions of replacement of cement
in terms of other mineral and chemical admixtures.
• Durability aspects can also be investigated with different proportions of admixtures.
• Studies can be made when the mixes are exposed to high temperatures.
