Abstract: Taking the mix design and construction control of freeze-thaw concrete in high cold area as an example. Based on the analysis and discussion of the mix proportion and construction control method of freeze-thaw concrete in alpine area, taking the construction of project A in Tibet as an example, this paper discusses the concrete method of mix proportion design and construction control of dynamic capacity concrete in alpine area.
Keywords: high cold area; freeze-thaw concrete; mix design; construction control
高寒氣候條件下的環(huán)境溫度對(duì)土方、混凝土及鋼結(jié)構(gòu)等項(xiàng)目影響較大,同時(shí)高寒地區(qū)施工技術(shù)與正常條件下的施工技術(shù)差異較大,導(dǎo)致高寒地區(qū)凍融混凝土配合比設(shè)計(jì)及施工控制措施成為廣大學(xué)者研究的重點(diǎn)。(剩余5399字)
