Since 1958 to 1978 this testing sand had been used for the production-monitoring of cement according to DIN 1164/58. For the strength development determination 3 cement mortar prisms (4 x 4 x 16 cm³) were prepared. Mix design: 450 g Cement, 450 g Standard Sand I (fine), 900 g Standard Sand II (coarse) and 270 g water.
The CEN Standard Sand DIN 1164, 1958 edition, is (naturally) rounded, quartz-rich Sand. Grain size I is ground Sand. The production-monitoring was operated by Normensand GmbH itself. In addition, the product was monitored by MPA Stuttgart. The test sieves used correspond to the regulations of DIN ISO 3310-1:2001-09.
Even today, the two individual grains (grain size I: fine, grain size II: coarse) are used for certain tests.
