Sand and Gravel Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO 2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.

How to Pack Down Rock Before Pouring Concrete Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn't drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains. Gravel allows water to drain into the ground below. When packed tightly, however, the gravel doesn't shift beneath the concrete.

Sand and Gravel For some applications, it is the silica content (quartz) of sand that makes it so valuable. The silica itself is needed to make products such as glass. In addition, the physical properties of sand, particularly its abrasive property, make it useful for traction on icy roadways and railroads, and for sandblasting.

Where is gravel found and how is it used by the building industry? Gravel is found naturally, mostly in lake, river, and ocean beds, where the constant movement of the water and waves keeps the gravel from settling and fusing with other rocks; sand is a form of micro-gravel, being tiny stones worn down by constant motion.
