Properties of Concrete by Replacement of Natural Sand

Artificial sand generally contain more angular particles with rough surface textures and flatter face than natural sand that are more rounded as a result of weathering. Over the time some investigations have shown that angular particles, rough surface of artificial sand influences the workability and finish ability in fresh concrete.

Mechanical Properties Of Recycled Aggregates Concrete

Depending upon their size, the aggregate are classified as the fine aggregate & coarse aggregates. The material passing through 4.75 mm sieve size is termed as fine aggregates. Natural sand or crushed sand is usually mainly as fine aggregates in concrete mixes. 1.2.1 NATURAL AGGREGATE Aggregates can come from either natural or manufactured sources.

Physical Prosperities of Aggregate : Grading Grading is the particle-size distribution of an aggregate as determined by a sieve analysis using wire mesh sieves with square openings. As per IS:2386(Part-1) Fine aggregate : 6 standard sieves with openings from 150 μm to 4.75 mm. (150 μm, 300 μm, 600 μm, 1.18mm, 2.36mm,
