Gradation and Size - Pavement Interactive
This shows that even a small amount of particles passing the 0.075-mm (#200) sieve results in very low permeability. Therefore, for base and subbase aggregates where permeability is important for drainage and frost resistance, many agencies will specify a maximum percent-by-weight passing for this sieve.
Sieve Analysis of Aggregates - Civil Engineering
sieve analysis Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.

What happened when we not used 20 mm size aggregate in ...
Your question is not clear. Do you want to use concrete with nominal maximum size of aggregate less than 20 mm (i.e. 10 mm, 12.5 mm or 6.3 mm) or you wish to have concrete with say NMSA 40 mm and jumping to 10 mm while grading.
Sieve analysis - Wikipedia
The results are presented in a graph of percent passing versus the sieve size. On the graph the sieve size scale is logarithmic. To find the percent of aggregate passing through each sieve, first find the percent retained in each sieve.
How To Do Sieve Analysis Of Aggregate | Quality Assurance ...
The most important test is the sieve analysis of aggregate, whether it is 20 mm, 10 mm, 5 mm and 1 mm sizes. The crucial thing is I have to do it every delivery of aggregate and as per the frequency of sieve analysis, which is written in this article frequency of tests. As a quality engineer in the concrete batching plant, you have to see to it that the sieve analysis is done regularly, as per ...
