Determination Of Percentage Of Crushed Aggregate

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness ...

Question: Is there an accurate, quick and inexpensive way to determine the percent of water in aggregate? Answer: I batch up to 100 cubic yards of concrete a week for our in-house projects, using all applicable admixtures. Because the water in the aggregate varies, I have to guess at the amount of water for each mix. This takes unnecessary time and extra trial batches.

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
