For the concreting purpose, we generally use coarse sand. The finest modulus of this sand should be 2.5 to 3.5 and it should not contain more than 4% silt. Classification of sand Fine Sand: The sand passing through a sieve with an opening of 1.5875 mm is called as the fine sand. Fine sand is mainly used for plastering works. Coarse Sand:

Depending upon the desired strength, the cement to the sand proportion of cement mortar varies from 1:2 to 1:6. Lime Mortar. Lime mortar is a type of mortar where lime (fat lime or hydraulic lime) is used as binding material and sand is used as fine aggregate. The lime to the sand proportion of cement mortar …

Classification on the basis of size of particles 15. Fine sand The sand passing through a sieve with clear openings of 1.5mm is known as fine sand.

Cement and sand are generally The soil which is used for preparing used as binding materials whereas sand, mud mortar should be free from grass, surkhi, cinder are used as fine aggregates pebbles etc. and crushed stones, gravel, broken bricks, These are the cheapest mortars but etc. are used as coarse aggregates in weakest in strength.

The construction materials list includes cement, steel, sand, concrete, ready-mix concrete, binding wires, aggregates, bricks, blocks, etc. apart from these, various eco-friendly construction materials are also used as construction materials.. Materials used in building construction have to be selected carefully to ensure the safety and long-lasting life of the building.

l When natural sand is replaced by geopolymer sand and artificial sand, the requirement of water is increased as the water absorption of these two sands is higher than natural sand. l Geopolymer sand and artificial sand can be used to replace natural sand as a fine aggregate as its compressive strength is more than mix with natural sand.

Most of the aggregates used are naturally occurring aggregates such as crushed rock, gravel and sand. Artificial and processed aggregates may be broken brick or crushed air-cooled blast furnace slag. AGGREGATES 38. FINE AGGREGATES The material smaller than 4.75mm size is called fine aggregate. Natural sands are generally used as fine aggregate.

When fine particles are in proper proportion, the sand will have fewer voids. The cement quantity required will be less. Such sand will be more economical. Demand for manufactured fine aggregates for making concrete is increasing day by day as river sand cannot meet the …

Fine aggregate is also divided into coarse sand, medium sand, fine sand and finer sand, whose fineness modulus is of 3.7 ~ 3.1, 3.0 ~ 2.3, 2.2 ~ 1. 6 and 1.5 ~ 0.7. According to production sources and materials, fine aggregate can be divided into ordinary river sand, mountain sand, sea sand, artificial crushed sand (stone chips), and waste sand.

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 (3/8 inch)
