WHAT IS THE GRADING LIMITS FOR COARSE AGGREGATES ...

27/06/2014  The grading of coarse aggregate may be varied through wider limits than that of fine aggregates, since it does not affect the workability, uniformity and finishing qualities of concrete mix. As per IS-383 the grading limit of coarse aggregate, both for single size as well as graded should be as per the table given below.

Gradation of Coarse Aggregates

Coarse aggregates used in concrete making contain aggregates of various sizes. This particle size distribution of the coarse aggregates is termed as “Gradation”. The sieve analysis is conducted to determine this particle size distribution. Grading pattern is assessed by sieving a sample successively through all the sieves mounted one over the other in order of size, with larger sieve on ...

THE CORRELATION BETWEEN AGGREGATE SHAPE AND

Aggregates shape, texture and grading have a significant effect on the performance of fresh concrete. Aggregate mixture with well- shaped, rounded, and smooth particles require less paste for a given slump than mix with flat, elongated, angular, and rough particles. At the same time, uniform grading with proper amounts of each size result in aggregate mixture with high packing and in concrete ...
