Quality Control - SCHWENK Sweden

Harmonized European Union standards and SCHWENK international quality requirements determine quality of cement made in Latvia. We thoroughly monitor the manufacturing process and perform laboratory tests of raw materials and ready-made products without compromising any quality traits.

SCHWENK product quality is based on the constant monitoring of the process. We perform control and tests of raw materials with the help of modern equipment – X-ray fluorescence spectrometer (XRF), X-Ray Diffractometer (XRD), Laser granulometer and other devices. Most important properties of cement are fineness, soundness, setting time, consistency and compressive strength after 2, 7 and 28 days as well as the chemical/mineralogical composition.

Harmonized European standards and international quality standards for SCHWENK establish the quality of cement manufactured in Latvia or other SCHWENK plants in Europe. We closely monitor the manufacturing process and carry out laboratory tests of raw materials and finished products on a daily basis.

Cement quality control complies with European standards, which determine the cement properties to be monitored, their frequency and limit values. According to these standards, cement products Viridiscement CEM II/B-M (S-LL) 52,5 N and Infracement CEM I 42,5 N-SR3 MH/LA manufactured in the Brocēni cement plant has received certificates of stable performance properties and CE marking. The certification body Kiwa, Latvia performs inspections and issues certifications. Kiwa performs monitoring audits in the cement plant annually but control of cement parameters – six times a year.

Rapidcement CEMI 52.5 R manufactured in Akmene, Lithuania has certificates for stable performance properties and CE marking issued by SPSC in Lithuania.
