In fact, the rubble usually consists in a mix of various construction and finishing materials, whose mechanical propertiesClassification of Aggregate used in Construction Purpose,As we mentioned above, the main classification of aggregate is fine and coarse aggregate.But the other types are cinder aggregate and broken brick coarse aggregate 1.Fine Aggregate The fine aggregate used for making mortar is silt and clay.The particle size of silt and clay is less than 4.75mm.Highly organic clay is also included in this classification.they are dark in colour, fibrous and bad,

Properties Of Aggregates | Properties Of Road And

The aggregate to be used in road construction should be sufficiently strong to withstand crushing and several stresses due to traffic wheel load. b.Hardness: The aggregates used in the surface course are subjected to rubbing or abrasion. So, the aggregate should be hard enough to resist wear and tear due to the abrasive action of traffic. c.Toughness: Resistance to impact is termed as,How to Choose Quality Coarse Aggregate for Concrete,,Coarse aggregates with a size of 20 mm or less are commonly used for the majority of concrete construction. One can roughly check the surface texture, particle shape, and cleanliness of the coarse aggregate just by visual observation. However, porosity and gradations require specific laboratory tests.Aggregates for Paving and Drainage | Pavingexpert,The proportions of the fine aggregate (sand), coarse aggregate (gravel), cement and water are varied to give concretes of different strengths and workabilities . The amount of water used to mix a given volume of concrete is determined by the Water:Cement ratio (W/C ratio) which works on the principle that a a smaller quantity of water (lower W/C ratio) results in a stronger concrete (assuming,
