The present research addresses the influence of using binary antifreeze admixtures on the strength performance of concrete under different curing exposures of cold weather conditions. A comparison with the strength performance of controlled concrete under the curing exposures of cold weather conditions is also explored. Calcium nitrate and sodium thiocyanate were the binary antifreeze admixtures used in the present study. Concrete specimens were cured at different cold weather conditions such as, 1) freezing temperature of -5ºC and -10ºC, 2) freezing temperature of -5ºC and -10ºC along with water revitalization, 3) freezing and thawing cycles, 4) freezing and thawing cycles along with water revitalization. The present study inferences that the synergetic use of calcium nitrate and sodium thiocyanate have a great influence on strength enhancement of concrete under the influence of various curing exposures of cold weather conditions that would be a constructive solution to promote the concrete applications in cold weather conditions.

本研究解决了在寒冷天气条件下不同固化暴露条件下，使用二元防冻剂对混凝土强度性能的影响。还探讨了与在寒冷天气条件下固化暴露下受控混凝土的强度性能的比较。硝酸钙和硫氰酸钠是本研究中使用的二元防冻剂。混凝土标本在不同的寒冷天气条件下进行固化，例如：1）-5ºC和-10ºC的冷冻温度，2）-5°C和-10ºC的冷冻温度以及水的再生，3）冷冻和解冻循环，4）冷冻和解冻循环以及水再生。
