Outdoor-exposed substrate concrete is susceptible to cracking and surface deterioration under combined environmental actions such as freeze–thaw cycles and deicing salts. The aim of this study is to evaluate the effects of binder composition and latex content on the strength and durability of substrate concrete and to provide basic data for mix design under combined deterioration conditions. This study evaluates 30 mixtures using a ternary binder of cement, fly ash, and ground granulated blast-furnace slag with latex contents of 0 %, 5 %, and 10 %. Slump flow ranged from 570 to 650 mm, air content from 3.0 to 4.0 %, and 28-day compressive strength from 53.0 to 77.4 MPa. Increasing latex content reduced freeze–thaw damage and deicer scaling, indicating improved durability and applicability for quality-controlled mix design. These findings can provide basic data for selecting suitable mix proportions for substrate concrete exposed to combined deterioration environments.
