ACI 222.1-96 PDF Download

ACI 222.1-96 is a provisional standard test method that focuses on determining the presence of water-soluble chloride in mortar and concrete, specifically its contribution to the corrosion of embedded steel. The standard provides detailed procedures for sampling and analysis of hydraulic-cement mortar, concrete, or aggregate for water-soluble chloride content.

The goal of this standard is to assess the potential for corrosion of embedded steel in mortar and concrete by quantifying the amount of water-soluble chloride present. Corrosion of steel reinforcement can compromise the integrity and durability of structures, so evaluating chloride levels is crucial for maintaining the long-term performance of construction materials.

The standard specifies the use of a Soxhlet extractor, a common laboratory apparatus, for the extraction of water-soluble chloride. This equipment ensures thorough and efficient extraction of chloride from the mortar or concrete samples. The extracted chloride is then analyzed through appropriate analytical techniques to determine its concentration.

By implementing ACI 222.1-96, engineers and researchers can accurately measure the water-soluble chloride content in mortar and concrete, allowing them to assess the likelihood of corrosion and make informed decisions regarding material selection or remediation strategies. This standard provides a reliable and standardized methodology to ensure consistency and comparability of test results.
