Chloride content in hardened concrete EN 14629
Parameters (quantitative): Chloride content [%]
Article Number: 2010205
Description: This norm describes two procedures for determination of the total of (free and bound) acid-soluble chloride in hardened concrete and hardened cement. This information is provided for the assessment of the danger of steel reinforcement corrosion by chloride. The procedure can be carried out on powder samples gained from concrete structures by drilling or from drill corn samples or from fragments or from other suitable laboratory test items. Mortar prisms are made available according to EN 196-1.
Category: chemical-physical testing material testing Hardened concrete
Accreditation: This proficiency test is within the scope of the A2LA accreditation.
