Abstract
The damaging impact of deicing chemicals on portland cement pervious concrete materials was investigated. Two concrete mixes (with and without latex modification) were subjected to three deicing chemicals (sodium chloride, calcium chloride, and calcium-magnesium acetate) under a freezing–thawing or drying–wetting condition. Two deicing chemical application methods (saturated and drained) were employed. The impact of deicing chemicals on the concrete was evaluated based on concrete mass and strength losses. Of the deicing chemicals studied, the calcium chloride solution caused the most damage, while the calcium magnesium acetate caused the least. The saturated scaling test method, followed according to ASTM C672, provided much higher mass loss of tested concrete samples when compared with a modified, more realistic drained test method.
