Study on Construction Technology of Hard Concrete for Parking Apron of Maun in Botswana |
| |
| Abstract: | To solving ventilation problems of Botswana Maun airport apron using hard concrete pouring venues with large areas, poor mobility and high quality requirements and political sensitivity of the construction, by means of field survey, technical analysis and field test, the overall construction planning of hard concrete, the quality of concrete mixing material and the supporting of mechanical equipment were confirmed and the formwork fabrication and installation and the concrete construction technology were put forward. Engineering practice shows that after construction, the mechanical properties such as compressive and wear resistance of the apron concrete fully meet the design requirements. The compressive strength of the flexural specimens and the core specimens reaches 100% of the designed strength, which can ensure smooth construction and quality requirements. Further, it can provide reliable reference for similar projects in the future. |
