This Singapore 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 light-weight, 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. 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 SS 78 : Part A17 and Part A21.
This method does not apply to aerated concrete, very stiff concrete, which cannot be compacted by vibration alone, and no-fines concrete.
