Webonly includes the aggregate particle. Since it includes the water permeable void volume, bulk specific gravity will be less than apparent specific gravity. 6.4.5 Bulk specific gravity (SSD) Definition: The ratio of the weight in air of a unit volume of aggregate, including the weight of water Web3. For a particular aggregate, the bulk specific gravity (Dry) was 2.67,the porosity was 3%, and the absorption was 1%. For another sample of the same aggregate obtained from another storing room, the moisture content was found to be 3%. Calculate: 1. The apparent bulk specific gravity 2. The bulk specific gravity (SSD) 3.
WebDec 6, 2024 · As you just stated, SSD stands for saturated surface dry. What we really use the term SSD for is to describe concrete substrates. It's really what we use to describe the moisture saturation of aggregates that go on concrete. It's one of four terms that we use. Oven dry, air dry, saturated surface dry, and then wet.
