Correlation Test between Resistivity and Microcosmic Pore Structure of Mineral Admixture Concrete
Cube crushing strength, resistivity and gas adsorption analysis of mineral admixture concrete are tested to analysis the effect of raw material on resistivity and its regression relationship with concrete microcosmic pore structure index. Test results show that concrete resistivity at different age increases with the increase of cementitious material and cement dosage, and both has a good nonlinear regression relationship. Concrete resistivity at different age decreases with the increase of 56d HK method cumulative pore volume, 7d and 14d resistivity has a good linear correlation relationship with 56d HK method cumulative pore volume. 28d and 56d resistivity has a good nonlinear regression relationship with 56d HK method cumulative pore volume. Concrete resistivity at different age decreases with the increase of 56d BJH method cumulative adsorption pore radius, and both has a good nonlinear regression relationship.
