aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 5-3) are used to produce struc-tural lightweight concrete with a freshly mixed density

However, SEM analysis shows that crushed shale particles always contain a large density of microfractures (Fig. 16). These microfractures could not exist under the effective stress conditions found in the subsurface and are likely to have formed either as a result of gas expansion during core retrieval or during the crushing process.

Compacted crushed shale is widely utilized as a construction material in roadway embankments. However, compacted shales are highly problematic as they tend to degrade with time once being subjected to cyclic weathering events. With degradation, shale converts from a hard rock-like material to a soft fine-grained soil mass with lower …

Sandstone. 2.2–2.8. Shale. 2.4–2.8. Slate. 2.7–2.8. As you can see, rocks of the same type can have a range of densities. This is partly due to different rocks of the same type containing different proportions of minerals. Granite, for example, can have a quartz content anywhere between 20% and 60%.

You would usually lay a 10mm aggregate at a depth of 30-40mm, but on a driveway this would need to be at least 50mm. A 20mm aggregate would need to be at least 40-50mm deep, and at least 50-60mm on driveways. A larger aggregate will settle and bond together better than smaller ones. The depth you will need to select for your gravel or slate ...
