The New Technique of Evaluation of the Early-Age Shrinkage Property of Concrete Material for Airport Pavement by Eddy Current

Abstract

This article introduces one new measurement technology for evaluation of the early age shrinkage performance of concrete material without constraint conditions. Its exercise of eddy current method could make the airport pavement concrete material tested accurately during concrete early-age from pouring, when the pavement concrete does not harden. It also can evaluate the effects of the influencing factors on the concrete early-age shrinkage, such as fly ash, admixture, and fiber. By this method, the Shrinkage performance of different concrete material can be evaluated when concrete property design for airport pavement is making.
