Article Synopsis
- The research paper discusses the diffusion coefficient values for twenty concrete mixes based on the thermodynamic migration model, highlighting discrepancies in values obtained through standard testing methods like ASTM 1202 and NT BUILD 492.
- The analysis reveals that the standard methods show significantly higher dispersion in results compared to the thermodynamic model, with ASTM C1202-97 having 2.8 times the dispersion and NT BUILD 492 showing 3.8 times the dispersion.
- The thermodynamic migration model is recommended as a promising approach due to its quicker testing process and applicability to a variety of concrete mixtures, though it still requires further testing with more concrete samples.
Variation of Electrical Resistivity and Charge Passed in High-Performance Concrete.

This study investigated the variation of bulk resistivity () and charge passed for various high-performance concrete (HPC) mixtures based on significant factors (i.e., geometric size, operation frequency, and mixture constituents and proportions) using three testing instruments.

The numerical modelling of chloride penetration into concrete is very sensitive to the correct description of the input data. In the recent era, high-performance concrete (HPC), which combines Portland cement and other supplementary cementitious materials, has been gaining attraction due to their desirable material properties and durability. The presented results show the application of the modified approach for the evaluation of the suitability of the time-dependent model for the variation of the diffusion coefficient.
