The characteristic of CEN-Standard Sand is its specific grain size distribution. It ranges between 0.08 and 2.00 mm. The grain size distribution is drawn in the picture (cumulated sieve residue in % vs squared mash size in mm) and listed in the table below. The maximum moisture content is 0.2%. The sand is portioned in bags of 1,350 (± 5) g. According to EN 196-1 mortar prisms for compressive strength testing are produced with a mixture of 450 (± 2) g cement, 225 (± 1) g water and one bag of 1,350 (± 5) g CEN-Standard Sand.
