Concrete Profile Grinder NT BUILD 443 and ASTM C1556.

The Profile Grinder is used to obtain concrete powder samples by precision grinding at small depth increments for accurate determination of the chloride ion profile for the following applications:
Following immersion of specimens in a chloride solution in the laboratory, e.g., according to NT Build 443 “Concrete, Hardened: Accelerated Chloride Penetration” or ASTM C1556 "Test Method for determining the Apparent Chloride Diffusion Coefficient of Cementitious Mixtures by Bulk Diffusion or
On-site on structures that have been subjected to chloride ion ingress.
