coarse and fine aggregates
Construction aggregate Wikipedia
Aggregates can be classified in many ways Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here 1 Fine Aggregate sand Fine aggregate includes the particles that all passes through 475 mm sieve and retain on mm sieve 2 Coarse Aggregate Construction aggregate or simply aggregate is a broad category of coarse to medium These products include specific types of coarse and fine aggregate designed for such uses as additives to asphalt and concrete mixes as well as other
Effect of Crumb Rubber as Coarse and Fine Aggregates on the
May 25 Synopsis The effects of using crushed concrete as coarse and fine aggregates upon strength and deformation of concrete are reportedThis procedure covers sampling of coarse fine or a combination of coarse and fine aggregates CA and FA in accordance with AASHTO T 2 91 Sampling from This research has used crumb rubber in asphalt mixture as a part of the coarse and fine aggregate Three sieve sizes of crumb rubbers were used in asphalt
