coarse and fine sand for concrete

Specification of Fine Aggregate/Coarse Sand

Fine Aggregate Fine aggregate/ coarse sand consists of natural sand, crushed stone sand or crushed gravel stone dust. It should be hard, durable chemically inert, clean and free from organic matter, not containing any appreciable amount of clay balls or pellets and other harmful impurities i. e. alkaline, salt, mica, decayed vegetation, lumps etc.

Aggregates for Concrete

• For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. • Aggregates are divided into either 'coarse' or 'fine' categories. - Coarse aggregates are particulates that are greater than 4.75mm.

4 – Blue metal (Coarse aggregate – 4 Times of Cement Quantity) The volume of concrete – (L x B x D) = 5 x 2 x 0.1 = 1 Cum. Volume of Concrete = 1 Cum. We find out the volume of concrete in wet condition 1m 3 (After the consolidation of Cement+sand+water). So in dry conditions, we have to add 30 to 35% sand bulkage and add 20% for wastage.

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
