Construction Technique And Quality Control Large Scale Finishing Concrete In Building Construction

Finishing concrete, which is not only a kind of structural material, but also a new sort of decorative material, is a new type of GPC and HPC. Great progress has been made on finishing concrete technology in foreign countries, but the geochronology development is juvenility and faultiness in our country. At present, there aren't still corresponding codes and standard, even inconsistent cognition of its definition has not been formed. In this dissertation, through academic analysis on fundamental performance requirements and mechanism, by summing-up successful experience of many projects, the definition and systematic construction method of finishing concrete have been sum up. The aim of dissertation is to offer a few commonplace remarks by way of introduction so that others may come up with valuable opinions about the study and development of finishing concrete technology.The main aim of this dissertationis is to study the technics and quality control of finishing concrete.In this paper, firstly, there are academic analysis of finishing concrete mixture on its main influencing factors and mechanism including the theological properties, the workability, the durability and so on. Thus, the theory basis has been established for putting forward the systematical construction technics of finishing concrete.secondly, on the basis of above theory analysis, summing up the successful experience of lots finishing concrete projects, bring forward the systematical construction technique of finishing concrete and their construction technique requirements. The construction technique includes reinforcing steel bar project, form project, concrete project and impermeability disposal of finishing concrete surface. Thirdly, set forth summarily the quality control principle of finishing concrete, according to the theory analysis; expound the familiar quality defect and their countermeasures. Fourthly, regarding research and development foundation of Lenovo in Beijing as a finishing concrete practice project, set forth particularly construction technique and technical-economical index of projects such as the reinforcing steel bar project, form project, concrete project and impermeability disposal of finishing concrete surface. At last, summarize the appliance prospect and the problems that need to solve at home.
