An experiment was carried out to compare electricalresistivity for six different low-permeability concretebridge deck mixtures. There were 26 measurements onconcrete cylinders for each mixture; these were obtained28 days after casting. The entries in the accompanyingANOVA table are based on information in the articleIn-Place Resistivity of Bridge Deck ConcreteMixtures (ACI Materials J., 2009: 114122).
