Confirmation of frost resistance of concrete and concrete products from an accredited testing laboratory
According to the Finnish Concrete Code the frost resistance of concrete must be determined in an accredited testing laboratory. Testing is carried out according to testing instruction VTT TEST R003-2010 to determine the spacing factor of air voids in concrete.
FCM specializes in the thin section technique and was the first testing laboratory in the concrete industry to receive accreditation (T208, SFS-EN ISO/IEC 17025). We have more than 17 years of experience in testing concrete using thin section techniques.
