Experimental Investigation and Strength Prediction Model for Unsaturated Concrete under the Coupled Action of Freeze–Thaw Cycles and Salt Erosion

Abstract

Abstract To study the changing law of compressive strength for concrete with different saturation degrees, water, sodium chloride (NaCl), and sodium sulfate (Na2SO4) solutions are used to erode concrete specimens. Concrete specimens with 0%, 20%, 40%, 60%...
