Using Modified Mortar-Bar Test Method to Access the Effects of Deicers on Expansion of Mortars With and Without Reactive Aggregates
Proceedings of the 4th International Conference on the Durability of Concrete Structures
The influence of deicing chemicals on alkali reactivity of aggregates is still an area of active research. The potential alkali reactivity of aggregates is often tested using the ASTM C1260 method. This research used the modified ASTM C1260 to test the potential alkali reactivity of aggregates. The modification included replacing the standard 1N sodium hydroxide (NaOH) used in ASTM C1260 with eutectic concentrations of the three common chloridebased deicing chemicals: sodium chloride (NaCl),doi:10.5703/1288284315431 fatcat:n36itpnkwna73apnk24rfom7pe
