Plaster Concrete Durability Research And Key Construction Technology

In recent years, many domestic requirements in concrete construction units do Free plastering standards. Free plastering concrete savings plaster layer construction, the construction process can be reduced, and good flatness. Free plastering concrete to increase the use of space, reduce construction costs, and reduce construction waste generated, with good economic and environmental benefits, and therefore avoid plastering concrete construction technology in China will have broad prospects for development. Since no current domestic related specifications Free plastering concrete, this paper will conduct research for Free plastering durability and key construction technology of concrete, to improve our Free plastering concrete construction technology and improve the quality of the project has a good practical sense.This paper mainly deals Free plastering concrete durability, reinforced protective layer construction, template selection, node structural design, material and casting technology and quality standards for analysis, the main contents are:(1) Free plastering concrete carbonation Experiment with ANSYS finite element software test simulation analysis; (2) Free plastering different structural parts of the protective layer of reinforced concrete analysis of control measures; (3) different template system for selection and design of key parts of construction research; (4) to avoid plastering and pouring concrete curing process research and analysis; (5) the actual construction of the Free plastering concrete quality standards for research.Through research of this paper the following conclusions:(1) Free plastering proposed minimum thickness of the protective layer of reinforced concrete by carbonation test and finite element software simulation; (2) Free plastering structural parts made of reinforced protective layer of control measures; (3) propose different architecture Free plastering concrete formwork system selection and design of the key parts of the structure; (4) Free plastering concrete requirements for selection, as well as construction elements made of concrete pouring plaster Free curing time; and (5) proposed Free plastering Concrete AQL.Results of this study have been used in the actual project, to achieve the desired effect, and the industry has been unanimous praise 5, has more important theoretical value and broad application prospects.
