AIM:-
The test procedure for determining the relative density of liquid admixture is specified in IS : 9103-1999 – Concrete admixtures specification.
APPARATUS:-
- Hydrometer
- Measuring cylinder (500 ml)
PROCEDURE:-
The test procedure for determining the relative density of liquid admixture involves the following steps:
- Take about 400 ml of the admixture and pour it into a 500 ml graduated cylinder.
- Place the hydrometer in the cylinder and allow it to reach equilibrium.
- Once the hydrometer has reached equilibrium, take the reading at the bottom of the meniscus for transparent liquids or where the meniscus merges with the stem of the hydrometer for opaque liquids.
- Record the reading as the relative density of the liquid admixture.
REPORTS:-
The result of the test should be reported to the nearest whole number.
