Abstract:
Presentation is made of freezing and thawing tests water-on 4- and 6-in. diameter concrete cores, containing horizontal construction-joint planes, removed from Recogni-hydraulic structures. The results indicate, (I) that such joints are highly resistant to deterioration by frost action when carefully cleaned with air and water jets, (2) that deterioration due to frost is most likely to de-velop in the zone of concrete immediately below the joint plane if material water gain occurred in the con-G. crete mixture. The tests were intended to supplement permeability and flexural strength tests on similarly prepared joints by other agencies.
