The Kelly ball test was formally standardized in ASTM C360-92: the name is “Standard Test Method for Ball Penetration in Freshly Mixed Hydraulic Cement Concrete.”
Advantages:
- The test is faster than the slump test.
I has been claimed that the Kelly ball test provides more accurate results than the slump
test.
Disadvantages:
- Like the slump test, the Kelly ball test is a static test.
- The test must be performed on a level surface of concrete
- Largea aggregate can influence the results of kelly ball.

Steps PROCEDURE Clean and dry the density bottle wash the bottle with water and allow it to drain. Wash it with alcohol and drain it to remove water. Wash it with ether, to remove alcohol and drain ether. Weigh the empty bottle with stopper (W1) Take about 10 to 20 gm of oven soil sample which is cRead more

Weight of density bottle + dry soil (W2 g)
Weight of bottle + dry soil + water at temperature T x0 C (W3 g)
Weight of bottle + water (W4 g) at temperature Tx0 C
INTERPRETATION AND REPORTING
Unless or otherwise specified specific gravity values reported shall be based on water at 270C. So the specific gravity at 270C = K�Sp. gravity at Tx0C.
