Coarse Aggregates: Types, Properites & Applications

Types of coarse aggregates: Elongated aggregate: Their size is 18 times or ninefifths of its mean dimension Flaky aggregate: At least the lateral dimension should be lower than 06 times or threefifths of the common dimension,Natural coarse aggregates: They are obtained by crushing rocks12122020· It consists mainly of quarry stones, gravel, uncrushed stones, and coarse aggregates greater than five millimeters Coarse Aggregate Sieve Analysis Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates The sieve analysis of coarse aggregate determines the gradation (the distribution of aggregate particles, by size, within a given sample) toCoarse Aggregate | Coarse Aggregate Size | Coarse29112020· The smallest sieve opening through which the entire amount of aggregate is almost passed (90%100%) is called the nominal maximum size (for 20 mm nominal maximum size aggregateall the material (90%100%) passes through 20 mm sieve) Aggregates for Normal Concrete Maximum nominal size of aggregate is used in design mix concrete It is different from maximum size of the aggregateFine aggregates (FA) and Coarse aggregates (CA) Material
