Construction planning for the placing of large quantities of concrete

Abstract

This study is attempted to identify the problems and to explore the more advanced of technical know-how involved in the process of large concreting work. The operational sequence, placement methods and the factors which influence the progress of concreting work on various construction projects are analysed. The types of construction included in this study are dams, bridge,underground power-house and high-rise building. Comparisons of the results has shown that the continuous placement method yield the better output in placing of large amounts of concrete, especially for massive reinforced concrete structures. However, this method is still not widely accepted in many construction projects. It is recommended that further study be conducted on the possibility of using this method specifically for dams; underground and under water structures as well as mass foundations. Finally, a proposed planning model and some relevant check lists are given as to provide construction planning for the placing of large quantities of concrete more meaningful.
