Determination of Density and Water Absorption

Bulk density cylinders with different capacities

Density is one of the most useful physical characteristics of aggregates. There are many procedures and test methods available to help obtain the most accurate measurements. When measuring density or water absorption rates for aggregates, different values can be obtained depending on the condition of the mass being considered in the calculations. In this section, you will find that our range of lab equipment satisfies all test procedures required by international standards.

Specific Gravity Frame and Baskets

Specific gravity determination of fresh and hardened concrete and aggregates.

Read more
   
Used with a suitable electronic balance for specific gravity determination of fresh and hardened concrete and aggregates. A purpose built robust frame designed to support the electronic balance.

The lower part of the frame incorporates a moving platform, which carries the water container allowing the test specimens to be weighted in both air and water. The balance is not included and has to selected conforming to the weighing range required. Any type of electronic balance fit with an underbench weighing facility can be used as, for example, all our models. See Balances, electronic. The frame has to be completed with the 11-D0612/A1 cradle, to hold concrete cubes or cylinders, or with the suitable Density basket for use with aggregates.
