Construction aggregate Wikipedia

Construction aggregate, or simply aggregate, is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as

The Importance of Aggregate Correction Factors in Air

Aggregate correction factor determination should be a part of routine testing, just like correction factors determined for ignition oven testing (AASHTO T 308/ASTM D6307). The first step to avoiding this nonconformity is to ensure that the laboratory's training program contains procedures and training guidelines for this process.

ASTM D6938 Standard Test Methods for In-Place Density

The dry density of the test sample is obtained by subtracting the water mass per unit volume from the test sample wet density (Section 11). Most gauges display this value directly. The gauge is calibrated to read the water mass per unit volume of soil or soil-aggregate.
