This Singapore Standard describes a method for making test beams of nominal sizes 150 mm x 150 mm x 750 mm long and 100 mm x 100 mm x 500 mm long 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 x 100 mm x 500 mm long beams and 40 mm for 150 mm x 150 mm x 750 mm long beams.
This method does not apply to aerated concrete, very stiff concrete, which cannot be compacted by vibration alone, and no-fines concrete.
