Abstract:

The Louisiana Department of Transportation and Development (DOTD) has required surface resistivity measurements for structural concrete applications since 2013. The 2016 Standard Specifications for Roads and Bridges includes this requirement. DOTD has investigated the use of saturated lightweight fi ne aggregate as an internal curing agent for structural concrete applications. Generally, when a concrete mixture contains saturated lightweight fi ne aggregate, the mixture’s resistivity is slightly less compared to a control mixture, but the reduction is not significant. The objectives of this research are to compare the surface resistivity (in laboratory conditions) of conventional versus internally-cured concrete containing the same basic cementitious combinations and contents and to better identify the eff ects of gravel versus limestone (i.e., siliceous versus carbonate) on surface resistivity measurements.
