| Abstract: | Beijing Greenland Center project involves 3.2m thick massive concrete foundation mat, whose local position is as deep as 9.1m, and one-shot concrete pouring quantity is more than 10,000m3. During massive concrete pouring, the lowest temperature reaches -20℃. Various measures are adopted, such as concrete mix proportion design, organization, etc., to successfully ice, snow and freezing ensure the construction protection, concrete crack control and production quality massive concrete. |
