The coarse aggregate grading requirements of ASTM C 33 AASHTO M 80 permit a wide range in grading and a variety of grading sizes The grading for a given maximumsize coarse aggregate can be varied over a moderate range without appreciable effect on cement and water requirement of a mixture if the proportion of fine aggregate to total aggregate produces concrete of good workability...

Learning Center What is the significance of aggregate grading Aggregates having a smooth grading curve and neither a deficiency nor excess of any one particle size will generally produce mixtures with fewer voids between particles Since cement costs more than aggregate and the cement paste requirement for concrete increases with increasing void content of the combined aggregates itFurther Details
Coarse aggregate is used to describe particles larger than 475 mm and the term fine aggregate is used for particles smaller than 475mm Fine aggregates contain particles in the size range 75 µm to 475 mm and coarse aggregates from 475 to about 40 mm except for mass concrete which may contain particles up to 150 mmFurther Details
The grading of aggregate influences the mix proportions for a specified workability and watercement ratio Coarser the grading leaner will be mix which can be usedFurther Details
Significance of Grading The particle size of fine aggregates sand substantially governs the properties of concrete mix such as workability pumping placing bond development and integrity of the resulted mass which are of prime importance while dealing with concrete Therefore it is fundamental for every Civil Engineer to ably comprehendFurther Details
Jun 25 2014 · We use cement paste to bind all the aggregates ie fine and coarse so as to give a compact mass and this is why concrete is considered as a two phase material namely paste phase and aggregate phase The paste has following disadvantages as compared to aggregate and which affects the concrete in its durability aspectFurther Details
Fig 2 Material grading charts for aggregates from Maryland a WG combined aggregate and b NWG combined aggregate The value indicated for each grading is the volume of the coarse aggregate divided by the total aggregate volume expressed as a percentFurther Details
An aggregate is the important material for concrete and also for the construction industry Concrete is widely used for constructing a house The significant reality is that some of 7080 of the amount of concrete volume is taken by the aggregates itselfFurther Details
Grading of Aggregates Grading of aggregates is determining the average grain size of the aggregates before they are used in construction This is applied to both coarse and fine aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed upFurther Details
The size of the aggregate bigger than 475 mm is considered as the coarse aggregate ie basically all other aggregates which are retained on 475mm IS sieve while sieve analysis is performed According to sources of coarse aggregates it can be further classified as a Uncrushed Gravel or Stone It results from natural disintegration of rockFurther Details
