Resistivity Characters of Concrete with Fly Ash and Slag

Abstract:

The resistivity characters of concrete with fly ash and slag are studied by four-pole method. The results indicate that concrete resistivity gradually increases with the content of fly ash or slag increasing within a given content scope. Fly ash can promote the concrete resistivity after long-term curing (＞28 days) and slag will increase the concrete resistivity during the early curing time (≤28d). When two mixed fly ash and slag, the effects of the ratio of them on concrete resistivity are similar to that of single mixed fly ash or slag. Otherwise, the change tendency of concrete resistivity are presented first increase and then drop with the content of mineral admixtures increasing, and concrete resistivity reaches the maximum when the total content is 30%.
