To strengthen the concrete surkhi is added.

2. Partial replacement of Sand with
Surkhi as fine aggregate in concrete
Batch - 4
Supervised by :- Dr.K.Varun Teja

3. Abstract
❖ Surkhi can be the future replacement for fine aggregate.
❖ Due to the abundant usage of concrete as a construction material,
there
is a fast dwindling source of aggregates. There are regions where there is
scarcity of fine aggregate, so to resolve this problem, surkhi can be used
as fine aggregate.
❖ Surkhi not only provides strength to concrete, it also provides an
economical support.

4. Abstract
❖ Surkhi is a brick powder . Brick is crushed and sieved through IS
4.75mm sieve.
❖ A partial replacement of surkhi as 10% , 20%, 30% for fine aggregate
are taken.
❖ The mix proportion of concrete had a constant water cement ratio of
0.50.
❖ 3 cube samples for each replacement of surkhi is tested.

5. Abstract
❖ In the process of partial replacement it is sieve to the fineness
of sand.
❖ Slump cone test was carried out on the fresh concrete and
compressive strength test on hardened concrete.
❖ Adhere mix 700 super plasticizer is used to increase the
workability of the concrete.
❖ The concrete cubes were tested at the ages of 14 days, and 28
days.

6. Introduction
❖ Concrete is one of the most versatile building material.
❖ It is a man-made construction material used extensively in buildings,
bridges, roads and dams.
❖ Adding some special ingredients such as admixture , super plasticizer,
etc ,. makes changes in the strength of the concrete.
❖ Surkhi in concrete is an interesting possibility for economy waste
disposal sites and conversation of natural resources.

7. Introduction
❖ The production of natural sand and cement is diminishing and their
use has led to severe environmental problems, there is a need to
replace there material by some cheap, environmental friendly by-
product such as surkhi (brick dust).
❖ It takes some weeks for concrete to reach full hardness and strength.

8. Objectives of the project
❖ To study the performance of concrete containing different percentages
of surkhi and to identify the suitable replacement percentage.
❖ To find the workability and compressive strength properties of
concrete produced by replacing surkhi by weight of sand.
❖ To investigate the effect on the strength of surkhi in concrete.
❖ To evaluate the compressive strength of high strength concrete by
partially replacing surkhi for fine aggregate.

9. Materials Required
❖ Cement.
❖ Fine aggregate
❖ Coarse aggregate
❖ Water
❖ Surkhi
❖ Adhere mix 700
