What is the significance and use of calculating

Many agencies use fineness modulus variation as a convenient means of keeping quality history data on uniformity of particlesize distribution of aggregate production, delivery, and use Some agencies require that aggregates be processed to remain within upper and lower limits of fineness modulusImportance of fineness modulus Products As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including, Importance of fineness modulus, quarry, aggregate, and different kinds of Importance of fineness modulus343 Fineness Modulus The significance of fineness modulus (FM) is in specifying the proportions of fine and coarse aggregates when designing concrete mixes The higher the value of FM, the coarser the aggregate Generally, a lower FM results in more paste, making the concrete easier to finishFineness Modulus an overview ScienceDirect

The fineness modulus is computed from screen analysis data by adding the cumulative percentages of aggregate retained on each of a specified series of sieves, and dividing the sum by 100 The sieves used for determining the fineness modulus are: No 100 (150 µm), No 50 (300 µm), No 30 (600 µm), No 16 (118 mm), No 8 (236 mm), No 4 (475 mm), 10 mm, 06102017 Fineness test of Cement:As per IS: 4031 (Part 1) – 1996 The cement of good quality should have less than 10% of wt of cement particles larger than 90 µm (micron) To determine the number of cement particles larger than 90 µm or Fineness test of cement The following apparatus is usedFineness test of Cement and its Significance 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 Significance of aggregate grading
