CHARACTERIZATION OF FRESH SCC PROPERTIES WITH ELECTRICAL RESISTIVITY

Abstract

The process of hydration and solidification of self compact concrete (SCC) has a significant influence on the long term properties. Characterization of fresh SCC's properties is an essential work for quality control and improvement of SCC. The study focuses on the characterization of fresh SCC properties with electrical resistivity measurements. The study adopts a non-contact resistivity measurement method that can provide accurate and reliable information of fresh SCC. The influence of various mineral, chemical admixtures and theological modifying agents on fresh SCC's properties can be identified by resistivity measurement. Other characterization methods such flow ability and segregation resistance of SCC can be related to electrical resistivity measurement. The characteristics points from electrical resistivity curves are correlated to the conventional and important parameters in construction practice
