EN 12390-8, “Depth of Penetration of Water Under Pressure”, Labbet Testing Laboratory, Prague, Czech Republic PERM-308

Concrete cube samples (150 mm) containing Xypex Admix C-Series NF were tested for
water permeability at 29 days, 91 days and 182 days. Design strength for the concrete
was C30/37 using CEM II/A-M 42,5R cement and 1031 Melnik I fly ash. Samples were
stored in at 20 +/-2°C and >95% Rh until test age. Water penetration at 29 days of age
was 25 mm, at 91 days of age the water penetration was 16 mm and at 182 days no
water penetration was measured.
