Effect of clay in fine aggregate

The Methylene blue test (BS EN 933-9) provides an assessment of the quantity of clay in a sample of rock or aggregate. No limits are given in UK standards as it is not considered sufficiently precise for the purpose of determining harmful fines content, see BS EN 12620 Annex D. The French National Standard has a limit of 1%.

08-04-2010· In road construction the general term fines is used to describe particles passing the 0.063, 0.074 or 0.08 mm sieve. Some types of fines are considered to be relatively inert and have almost no effect on pavement performance, whilst the presence of even small amounts of others can significantly affect the stiffness and freezing–thawing behaviour of unbound and hydraulically bound layers.
