7. Investigation Of Soil

8. Objective
This test is common used in situ test especially for
cohesion less soil. Which can not be easily sampled . The
test extremely used for determine the relative density and
angle of Shearing resistance of cohesion less soils. It can
also determine unconfined Compressive strength of
cohesive soils.

9. Appratus used
 Tripod Stand.
 Standard Spoon Sampler
 Guide pipe
 Drill rod
 Drop hammer weighing 65kg
 Center point

for high rise building.
After digging the bore hole . The sample is taken from
5ft,10ft,15ft & 20ft depth so on with the help of sampler
equipment.

19. TESTS ON HARDENED
CONCRETE

20. NON-DESTRUCTIVE TESTS
REBOUND HAMMER
To assess the likely compresive strength of concrete by using rebound
hammer.
As per IS: 13311 (Part 2) - 1992.

21. PRINCIPLE
The rebound of an elastic mass depends on the hardness of the
surface against which its mass strikes. When the plunger of the
rebound hammer is pressed against the surface of the concrete, the
spring-controlled mass rebounds and the extent of such a rebound
depends upon the surface hardness of the concrete. The surface
hardness and therefore the rebound is taken to be related to the
compressive strength of the concrete. The rebound value is read
from a graduated scale and is designated as the rebound number or
rebound index. The compressive strength can be read directly from
the graph provided on the body of the hammer.

22. APPARATUS
1.The Rebound Hammer has two types
Graphical Rebound Hammer
Digital Rebound Hammer
2. Scanner
 RF Scanner

24. Scanner

25. Rebound Hammer

26. PROCRDURE
Before commencement of a test, the rebound hammer should be tested
against the test anvil, to get reliable results, for which the manufacturer of
the rebound hammer indicates the range of readings on the anvil suitable for
different types of rebound hammer.
Apply light pressure on the plunger - it will release it from the locked
position and allow it to extend to the ready position for the test.

27. Press the plunger against the surface of the concrete, keeping the instrument
perpendicular to the test surface. Apply a gradual increase in pressure until the
hammer impacts. (Do not touch the button while depressing the plunger. Press
the button after impact, in case it is not convenient to note the rebound reading in
that position.)
Take the average of about 15 readings.
