  • Properties of aggregates for concrete

    Aggregates are chemically inert, solid bodies held together by the cement. aggregates come in various shapes, sizes, and materials ranging from fine particles of sand to large, coarse rocks. natural aggregates are formed by process of weathering and abrasion.

  • Aggregates

    Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. those particles that are predominantly retained on the 4.75 mm no. 4 sieve, are called coarse aggregates. those particles passing the 9.5 mm 38.

  • Concrete aggregates

    Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm. fine aggregates contain particles in the size range 75 m to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for mass concrete which may contain particles up to 150.

  • Influence of aggregate characteristics on concrete
