The Effect of Aggregate Properties on Concrete, Aggregate is classified as two different types, coarse and fine Coarse aggregate is usually greater than 475 mm (retained on a No 4 sieve), while fine aggregate is less than 475 mm (passing the No 4 sieve) The compressive aggregate strength is an important factor in the selection of aggregateGradation of Aggregate | Ultimate Guide, Apr 11, 2020· Fine-Aggregate Grading Fine-aggregate grading depends on the type of work, the richness of mix, and the maximum size of coarse aggregate; Fine-aggregate grading within the limits of ASTM C 33 is generally satisfactory for most concret The ASTM C ,Bulk density and bulking of fine and coarse aggregate, Dec 18, 2019· For ordinary sands the bulking usually varies between 15 to 30 percent Fine sand bulks more and the maximum bulking is obtained at a higher water content than the coarse sand In case of coarse aggregates the increase in volume is negligible Extremely fine sand and particularly the manufactured fine aggregate bulks as about 40 percent 9Sieve Analysis of Coarse and Fine Aggregates, Aug 31, 2020· Combined gradation means fine and coarse aggregates are combined (friction at many points, good interlocking, and few voids, economical) Gap grading is a grading in which one or more intermediate sizes are omitted in order to achieve a desired ,Functions Of Fine and Coarse Aggregate in Concrete, May 29, 2019· 2 It assists the cement paste to hard the coarse aggregate particl 3 It helps to prevent possible segregation of paste and coarse aggregate particularly during the transport operation of concrete for a long distance 4 Fine aggregate reduces the ,.
