Site Test ~ apart from the test outlined on page 83 site tests on
materials which are to be combined to form another material such
as concrete can also be tested to establish certain properties
which if not known could affect the consistency and/or quality of
the final material.
Typical Example ~ Testing Sand for Bulking
This data is required when batching concrete by volume † test
made at commencement of mixing and if change in weather
Therefore volume of sand should be increased by 21% over that
quoted in the specification
NB. a given weight of saturated sand will occupy the same space
as when dry but more space when damp
