Work Item
ASTM WK96505
Revision of C1778-23 Standard Guide for Reducing the Risk of Deleterious Alkali-Aggregate Reaction in Concrete
Rationale
Recent research has found that the 2-year concrete prism test has been found to underestimate the percentage replacement or dosage rates for SCMs or lithium nitrate, respectively, for high alkali loading mixtures. This new wording will warn users from using ASTM C1293 for mitigation in high alkali content mixtures as it may not be conservative.
