Specific Gravity and Buoyancy Balance density of hardened concrete specimens such as cubes and cylinders can be quickly and accurately determined using a Buoyancy Balance.

The balance will be with under hook weighing arrangement and will be mounted on suitable table to facilitate the test. The Water tight container will be mounted on a mechanical jack, which will facilitate the up?down movement of the container for weight in air and water.

Specific Gravity Frame is used in conjunction with a suitable electronic balance for specific gravity determination of fresh and hardened concrete and aggregates. The buoyancy balance system consists of a rigid support frame, incorporating a water tank mounted on a platform. A mechanical lifting device is used to raise the water tank through the frame height immersing the specimen suspended below the balance. The balance supplied may also be used as a standard weighing device, thus providing a versatile and comprehensive weighing system in the laboratory
