| Abstract: | With general consideration of the concrete frame of blast furnace with a big surface coefficient in winter construction, a comprehensive thermos methods had been taken, which included the choose of anti—freezing admixture, concrete curing, construction process and measures, as well as strength control of form removal. Therefore, a satisfied result was obtained. |
