CONCRETE/REINFORCING STEEL BOND STRENGTH OF LOW-TEMPERATURE CONCRETE

The cost of protecting freshly placed concrete from freezing damage is about $800 million annually in the United States. Lowering the freezing point of water using chemical admixtures allows concrete to gain strength at temperatures that are below the freezing point of water. This study examines the bond strength of the reinforcing steel and concrete in concrete cured at below freezing temperatures with an antifreeze admixture of sodium nitrite and calcium nitrite. Results suggest that concrete developed with this antifreeze admixture and cured below 0 deg C will gain strengths comparable to concrete cured above 0 deg C without antifreeze admixtures.
