How To Check If Stone Chips Are Good?
The visual tests or field tests for Coarse
aggregate, that is stone chips are very limited though there are many
laboratory tests are available. Mainly the following things are observed as for
Field Test:-
1. The Stone Chips are to be well graded to increase
the mechanical interlocking between them.
2. Stone Chips should be Angular as far as possible
and be porous.
3. The Stone Chips should not be flaky and elongated.
4. The Stone Chips should not contain organic and
other impurities, as only 5% of clay content in concrete can reduce the strength
of the concrete as much as 20%.
