Abstract : Results from alkali-reactivity and freeze-thaw tests are summarized. Results of petrographic examinations of concrete specimens and of physical properties tests performed on the test aggregates are appended. Concretes containing Republican River sand were somewhat more resistant to freezing and thawing than comparable concretes containing aggregate from the Arkansas River when these aggregates were used in combination with high-alkali cement, a quarried limestone coarse aggregate, or an innocuous natural coarse aggregate. However, when used in combination with a reactive coarse aggregate, the reverse was true. Results of the alkaliaggregate reactivity tests indicated sands from both sources are highly reactive.
