Specific Gravity Frame


The Specific Gravity Frame is used in conjunction with a suitable electronic balance for specific gravity determination of fresh and hardened concrete and aggregates.

It consists of a purpose built, robust frame designed to support the electronic balance (not supplied), a wire basket and plastic water tank. The lower part of the frame incorporates a moving platform, which carries the water tank allowing the test specimens to be weighed in both air and water. Any type of electronic balance fitted with under-bench weighing facility can be used.

The Specific Gravity Frame is supplied complete with:

  • A water tank
