How sand is made

The stones were rubbed on a piece of wetted sandstone to hone the cutting edge. In some cases, loose sand was scattered on a flat rock, and objects were rubbed against the sandy surface to smooth them. The first beads with a glass glaze appeared in Egypt in about 3,500-3,000 The glass was made by melting sand, although naturally-occurring glass formed …

Aggregates for Concrete

aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.

How Aggregates Are Extracted

How marine aggregates are extracted. A significant proportion of the demand for aggregates is satisfied from river, lake, and sea beds. Our marine resources are an increasingly important alternative source of aggregates. Marine aggregates play an important role in replenishing beaches and protecting coastlines from erosion.

Aggregate (composite)

Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel
