Aggregates for Concrete

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate The aggregates are usually washed and graded at the pit or plant Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

Are compaction tests of #610 crushed stone reliable

Aug 06, 2005· If your stone has become segregated (is not sweet, has “rock pockets”) then you will get these low in-place density test results Make sure that your stone is well mixed and that it actually meets the gradation requirements for #610, that an accurate proctor is being used, and that your material is at or near the optimum moisture content.

optimum moisture content of crushed stone

optimum moisture content of crushed stone The materials were tested at or near the maximum dry density, which varied from 1962 kg/m 3 (1225 pcf) (low fines content crushed stone) to 2300 kg/m 3 (1436 pcf) (high fines content crushed stone) and the optimum moisture content, which varied from a low of 40 percent (low fines content crushed stone) to a high of 90 percent (partially.

Aggregate in Concrete

Both gravel and crushed stone are generally acceptable for making quality concrete (Photo 9), although gravel is usually preferred for exposed aggregate The use of recycled concrete, crushed to proper-size concrete aggregate, has also demonstrated successful performance.
