1. SCOPE 1.1 Use this test method to determine the particle size distribution of aggregate samples, using standard U.S. sieves with square openings. 1.2 Use Part I to determine a weight-based, dry-sieve analysis for an aggregate sample. 1.3 Use Part II to determine a weight-based, sieve analysis for an aggregate sample requiring a washed sieve
properties, Aggregate provide bulk, strength and wear resistance in these application. Hence, the selection and proportioning of aggregate should be given careful attention. The aggregate is generally coarse gravel or crushed rocks such as limestone, or granite, along with a fine aggregate such as sand or stone dust.

3 1.5 SCOPE OF STUDY The main purpose of this study is to investigate the engineering properties of concrete produced using coarsely crushed cockle shell as coarse aggregate replacement.
The Coarse Aggregates are the crushed stones extracted from crushing large rock quarry, boulders, or gravels (larger size). And the majority of the coarse aggregates constitute crushed gravels or stones. * They normally range 40mm, 20mm, 14mm, and 10mm aggregates.
Construction aggregate is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic
