Abstract

The influence of selected iron chelating agents upon corrosion and cracking of steel reinforced concrete has been investigated. Five chelating agents including EDTA, DTPA, TEA, HEDTA and Chel-138 were used. The experiments involved determination of (1) the influence of iron chelating agents on iron solubility limit, (2) the effect of admixtures upon compressive strength of concrete, (3) the influence of chelating admixtures upon steel corrosion and (4) cracking resistance of concrete specimens with and without selected iron chelating agents. Results from test groups (1) and (3) were encouraging; however, compressive strength of concrete specimens with admixtures was less than for specimens with no admixture. In addition, specimens with chelating admixtures had approximately 5.5 to 82 percent shorter cracking time than for the no admixture ones. Explanations for this are presented, and certain conclusions are reached regarding the usefulness of a chelating admixture for mitigating concrete cracking.
