SATURATED SURFACE DRY (SSD) - Saturated surface-dry is the condition of an absorptive material where the material is saturated but its surface is dry. Saturated surface dry aggregate neither absorbs water from or contributes water to the concrete mixture. WATER-CEMENT RATIO (w/c) - The water-cement ratio of a concrete mix is the

Bulk Density - Measurement | Fact Sheets |

Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha). Background. The soil bulk density (BD), also known as dry bulk density, is the weight of dry soil (M solids) divided by the total soil volume ...

Soil mechanics - Faculty of Environment and Technology

Density is a measure of the quantity of mass in a unit volume of material. Unit weight is a measure of the weight of a unit volume of material. There are two basic measures of density or unit weight applied to soils: Dry density is a measure of the amount of solid particles per unit volume.

It has strong cohesion (attraction between particles) and is commonly called a cohesive soil. ... AASHTO definition gravel will pass the 3 inch sieve and be retained on the No. 10 sieve.


Surface area of soil affects its physical and chemical properties and is largely determined by amount of clay present in soil: Specific surface area of soil particles Effective Area Specific Surface Area Particle Diameter (cm) Mass (g) (cm2) (cm2 g-1) Gravel 2 x 10-1 1.13 x 10-2 1.3 x 10-1 11.1 Sand 5 x 10-3 1.77 x 10-7 7.9 x 10-5 444.4

The Effect of Aggregate Properties on Concrete

The moisture content can range from less than one percent in gravel to up to 40 percent in very porous sandstone and expanded shale. Aggregate can be found in four different moisture states that include oven-dry (OD), air-dry (AD), saturated-surface dry (SSD) and wet.
