Aggregate Sizing Explained, Jan 15, 2016· For example coarse aggregate has a standard grading requirement for each different size from #1 to #8 A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal size of 3/8 to 0094 inch More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 019 inch ,Classification of Aggregates Based on Size and Shape ,, Aggregates are available in nature in different siz The size of aggregate used may be related to the mix proportions, type of work etc the size distribution of aggregates is called grading of aggregat Following are the classification of aggregates based on size: Aggregates are classified into 2 types according to size Fine aggregateCBSE Grading System Class 10 & 12: Calculating Percentage ,, CBSE Grading System: The Central Board Of Secondary Education (CBSE) has introduced a grading system for the students of Class 10 & 12 from the academic year of 2009 to 2010So, now the students will be awarded on a 5 point scale grading system that is from Grade A to Grade EThe CBSE grading system is decided based on the 2 parameters that are Absolute & Percentile MarksCOMMON TOXICITY CRITERIA (CTC), CTC Version 20 Publish Date: April 30, 1999 Cancer Therapy Evaluation Program 4 Revised March 23, 1998 Common Toxicity Criteria, Version 20 DCTD, NCI, NIH, DHHS March 1998ASTM C131 / C131M, Note 1: A procedure for testing coarse aggregate larger than 190 mm [3 / 4 in] is covered in Test Method C535 Thus coarse aggregates with a maximum size between 19 mm [3 / 4 in] and 375 mm [1 1 / 2 in] may be tested by Test Method C535 or Test Method C131/C131M.
