How Quicksand Works
It can occur almost anywhere if the right conditions are present. Quicksand is basically just ordinary sand that has been so saturated with water that the friction between sand particles is reduced. The resulting sand is a mushy mixture of sand and water that can no longer support any weight. If you step into quicksand, it won't suck you down.
What Is the Difference Between Washed Sand & Silica Sand
Jul 17, 2017 · Once the sand is mined it is often washed with water to remove salt, silt, clay, dust and powder. Sand also is often separated and classified according to size as it gets washed. Washed sand comes in coarse, medium, fine and ultra fine granule sizes, of which each size classification requires sand granules that are within a specific diameter range.
Lecture 4. Aggregates
• Artificial aggregates are made out of various waste materials. • Artificial aggregates are sometimes produced for special purposes: - for making lightweight concrete: burned clays, artificial cinders, foamed slag, expanded shales and slate, sintered fly ash exfoliated vermiculite are used - for making heavy- weight concrete: steel rivet
