Conductivity behavior of the fresh CA mortar and its relationship with the fluidity properties

Abstract: In order to find a new test method to investigate the relationship between the compositions and fluidity of the cement and emulsified asphalt mortar (CA mortar), the conductivity and the fluidity properties of the fresh CA mortar with different mixtures were studied by analysis of the relationships among the liquid fraction, the “J” type funnel flowing time and the conductivity. Results showed that (1) the electrical conductivity was linear relationship to the liquid volume fraction of the slurry, but markedly influenced by thickening agent, (2) there exist apparent relationship between the flowing time of fresh CA mortar through “J” type funnel and liquid volume fraction, also and electrical conductivity, (3) the difference of the density showed good linear relationship with the difference of the electrical conductivity caused by the segregation.
