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. WebWhereas, bulk specific gravity (BSG) is a measure of the weight/volume of solids and pores of a material. ASG > BSG SSD > BSG OD However, since the porosity of most rocks used in concrete is 1 to 2%, the values of all specific gravities are approximately the same; in the range of 2.5 to 2.8.
