3. ABSTRACT
Concrete is one of the most widely used material in building
construction. In modern days concrete is loosing its properties
when subjected to environmental condition.
Hence there is need to enhance the properties of concrete and
various additives are added in cement to improve the properties
of concrete.
In this project studies were carried out using tamarind kernel
powder as an additive. It was observed that there was
improvement in strength with addition of tamarind kernel
powder.

4. The purpose of this project is to experimentally investigate
the effect of tamarind kernel powder in structural concrete is
added to improve the strength of concrete.
Many types of tamarind kernel powder are used for concrete
reinforcement. tamarind kernel powder are the most common
type.
The use of tamarind kernel powder concrete is more precise
configuration compared to normal concrete. In this project,
Adding the Tamarind kernel powder as 0%, 5%, 10%, 15%
and 20%. It will develop a high performance concrete.

5. INTRODUCTION
 Sustainability was a big issue that being concern in making a
development.
 This is because sustainable development has become a key
aspect in society, Economics and development.
 Sustainable development shall meet the needs of the present
without compromising ability of future generation to meet
their own needs.
 It also shows that development that going to be made to
sustain the planetary resources by using them effectively
without making unnecessary wastage.

6.  The usage of Tamarind kernel to replace the Coarse
aggregate, is because the production of the Coarse aggregate
emits carbon dioxide gas to atmosphere. The Coarse
aggregate industry is held responsible for some of the carbon
dioxide emission, because the production of one ton Portland
Coarse aggregate emits approximately one ton of carbon
dioxide gas into the atmosphere.

7. OBJECTIVES
 To use industrial waste Tamarind kernel for the
manufacture of concrete which otherwise would have been
a disposal.
 To reduce the quantity of Coarse aggregate in manufacture
of concrete.
 To increase the strength of concrete by partial replace
Coarse aggregate of Coarse aggregate with Tamarind
kernel.
 To study and find permeable voids of the concrete mix and
its relation with compressive strength of concrete.

8. SCOPE OF PROJECT
 Improving strength and durability properties of concrete.
 Reduces a good part of total carbon dioxide emitted.
 Introduction of new construction material

9. TAMARIND KERNEL
Tamarind kernel, also known amorphous (non-crystalline) polymorph of silicon
dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon
and ferrosilicon alloy production and consists of spherical particles with an
average particle size of 150 nm.

10. LITERATURE REVIEW
S.Bhanjaa, 2002, “Investigations on the compressive strength of
Tamarind kernel concrete using statistical methods” et al.,
Extensive experimentation was performed to determine the isolated
effect of Tamarind kernel on the properties of concrete over a wide range
of w/cm ratios varying from 0.3 to 0.42 and Tamarind kernel replace
Coarse aggregate percentages ranging from 5 to 30. On the basis of
regression analysis of a large number of experimental results, a statistical
model has been developed, which can serve as a useful tool for optimizing
and predicting the strengths of Tamarind kernel concretes over a wide
range of replace Coarse aggregate percentages and w/cm ratios ranging
from 0.3 to 0.42. This model, involving nondimensional variables, is
independent of the specimen parameters.

11. Edward Jenner, 2012 “Experimental Investigation on Micro silica (Tamarind
kernel) As Partial Coarse aggregate Replace Coarse aggregate in Concrete”
International Journal of Modern Engineering Research (IJMER) et al.,
Coarse aggregate replace Coarse aggregate up to 10% with Tamarind kernel
leads to increase in compressive strength, for C30 grade of concrete. From 15% there
is a decrease in compressive strength for 3, 7, 14 and 28 days curing period. It was
observed that the compressive strength of C30 grade of concrete is increased from
16.15% to 29.24% and decrease from 23.98% to 20.22%. The maximum replace
Coarse aggregate level of Tamarind kernel is 10% for C30 grade of concrete. Both
the physical and chemical properties of micro silica and Coarse aggregate are in
compliance with the standard except SO3 analyzed from Coarse aggregate. Based on
the conclusions arrived at, the following recommendations are made for future work:
It is recommended that testing of concrete produced with micro silica concrete be
extended to 56 or possibly 90 days to further determine the pozzolanic ability of the
micro silica.

20. CONCLUSION
 Compressive strength of Tamarind kernel concrete was
higher than conventional concrete.
 The optimum 7 and 28 days compressive strength has been
obtained in the range of 15% Tamarind kernel replace of
Coarse aggregate level.
 When compare to other mix the loss in weight and
compressive strength percentage was found to be reduced by
2.23 and 7.69 when the Coarse aggregate was replaced by
15% of Tamarind kernel.

21.  Tamarind kernel used as a partial replace Tamarind kernel
of Coarse aggregate enables the large utilization of waste
products. Compressive strength containing 15% of
Tamarind kernel is acceptable No for most structural
applications.
