Proposed Method to Reduce Magnesium Chloride Deicer Damage to Pervious Concrete
Publication: Journal of Cold Regions Engineering
Volume 35, Issue 3
Abstract
This technical note tests the efficacy of a carbonate-laden water treatment on pervious concrete to increase its resistance to magnesium chloride (MgCl2) attack. A treatment method and an example of the method application are described. The method consists of applying MgCl2 deicer onto pervious concrete specimens for 17 weeks, but some specimens are treated prior to the deicer applications and some are not. All specimens are then subjected to compressive strength tests and to optical microscopy, for visual analysis of the interfacial transition zone. In the example given, the time frames between casting and treating or applying deicer varied, and although inconclusive, results indicated that the treatment might be more effective if more curing is allowed prior to treatment.
