| Abstract: | The chapter Ⅹ of Code for construction of concrete structures GB50666—2011 includes aspects of general requirements,cold weather requirements,hot weather requirements and rainy weather requirements,which adds the contents of hot weather and rainy weather construction.Furthermore,compared with Code for construction and acceptance of concrete structures GB50204—92,the part of steel bar construction in cold weather is placed in steel bar engineering chapter.The assurance of temperature limit,importance of thermal calculation of concrete,selection of cement,selection of admixture,preheating of original material and maintenance of concrete are introduced for cold weather construction.The joining condition in hot weather,the special scheme and construction measures for hot weather construction are indicated.The quality control and safety control during construction for rainy weather construction are described. |
