Development of Standard Methodology to Measure Sulfate Ions in Post-Tensioned Grouts
项目名称: Development of Standard Methodology to Measure Sulfate Ions in Post-Tensioned Grouts
摘要: The objectives of this study are to: (1) Identify the extent that vestigial sulfur-bearing cement or grout constituents contribute to sulfate ion levels in hardened and deficient grout pore water. (2) Identify sulfate ion transport mechanisms in grouts in tendons with vertical deviation. (3) Identify if sulfate content in raw grout materials or from laboratory bleed water tests can be used to characterize corrosion sulfate limits. (4) Identify the effects of grout sampling methodologies on hardened and deficient PT grout for total and water soluble sulfate levels.
