This Part of this British Standard describes a
method for making test cylinders of nominal
diameter 100 mm and 150 mm out of fresh concrete.
The method applies to plain and air-entrained
concrete made with lightweight, normal weight and
heavy aggregates having a nominal maximum size
not exceeding 20 mm for 100 mm cylinders
and 40 mm for 150 mm cylinders.
NOTE 1 A cylinder produced for determining tensile splitting
strength should preferably be of 150 mm diameter with a length
of 150 mm. A cylinder produced for determining the static
modulus of elasticity should preferably be of 150 mm diameter
with a length of 300 mm. See BS 1881-117 and BS 1881-121.
This method does not apply to aerated concrete, very
stiff concrete, which cannot be compacted by
vibration alone, and no-fines concrete.

standard are listed on the inside back cover
