The main objective of this study was to evaluate the effects of different types of deicers (CaCl2, MgCl2 and NaCl) on pavement concrete containing coarse slag aggregate and exposed to freezing-thawing (FT) and wetting-drying (WD) conditions.The study involved evaluation of concretes with two types of binders: plain concrete (prepared using ASTM C 150 Type Ⅰ portland cement (PC)) and concrete with binary binder system (Type Ⅰ PC and Class C Fly Ash (FA) at 20% weight replacement).The effects of different deicers on the concrete were assessed by conducting experimental tests on concrete specimens both during and after the exposure period (347 FT and 286 WD cycles).The mechanical properties of hardened concretes were assessed by measuring their compressive strength.
