4. In this project, we have to propose tamarind kernel
powder as an additive in the concrete.
Concrete is one of the most widely used materials in
In morden days concrete is losing it’s 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.
From the experimental results, it is observed that the
concrete exhibits improved compressive strength when
compared with the conventional mix.

N.V Venkat seenivasan, H. Devaki VOL.7 jan 2018.
In this research,using tamarind kernel powder in concrete possess
high workability, high dimensional stability, high durability, low
permeability and esistance to chemical attack.
The tamarind kernel powder can improved compressive strength
spilt tensile strength and compressive strength when compared with
the conventional mix.

Tamarind seed is an under utilized product of the tamariend pulp
industey. Only a small potion of the seed in the form of TKP is used
as a sizing material in the textile paper and jute industery.
The setting time of concretecan be takes 2 to3 days.
The load carring capacity of reinforced concrete cubes is increased
with the addition of TKP.Stiffness value is increased for TKP admixed
concrete than the conventional concrete.

The TKP can increase the workability and compressive strength. It
can increase the compressive strength.
The gum is composed with simpler sugars material such as
guikopiranosa and of glucose xilose and galaxtose.
Higher od starch level in powder will be increase gel strength.
11. The specimen of standard cube (150x150x150) mm
were used to determine the compressive strength of the
concrete three specimend were tested for 7,14 and 28 days
of each proportions partilly replacement of tamarind kernel
powder totally 9 cubes.

13. From the result it was found that 3% is the maximum
replacement of cement by tamarind kernel powder.

20. The addition of TKP was found effectively improved
the properties of concrete. The compressive strength is increased with
the addition of 1.5% TKP. From the results it is conclude that tamarind
kernel powder (TKP) can be used to improve the properties of concrete.
The compressive strength of concrete cubes is increase with the addition
of TKP. Stiffness value is increased for TKP admixed concrete that the
conventional concrete. The result of compressive strength test indicated
the strength of concrete increase with respect to the percentage of TKP
is added by the weight of cement unto 1.5% of addition and gradually
the strength decreases when the percentage of TKP is added by the
weight of cement to 3% .
The well defined scope in the future studies of TKP is that it can
also be replaced by cement very easily and the concrete has gives more
