Suggestion of Management Method of Ready-Mixed Concrete (RMC) Pouring Centred on Construction Site

Abstract

In construction sites, ready-mixed concrete (RMC) is one of the most important materials that should be unloaded and placed on the site within the standard time (60 ∼ 90 minutes) immediately after shipment from RMC plants due to the characteristics of the material. In addition, longer waiting time and pouring time during concrete pouring process affects the quality of RMC significantly. Therefore, the time-based delivery management for fluent supply and demands is the most important issue in RMC placement plan. For this reason, optimization research has been carried out on the RMC vehicle tracking and RMC delivery management algorithms. However, they were more of RMC companies centered truck dispatching and pouring management, and there were few studies on construction site centered RMC installation planning and management. Moreover, the information from RMC truck invoices and the time information of RCM truck, such as plant departure time, on-site arrival time, and turnover time, are limitedly considered in RMC placement planning and quality control. Therefore, the purpose of this study is to derive the necessary parameters for field-oriented RMC management process using information from the invoice and RMC management process used at the construction site. Especially, the necessity of the management of pouring time using the pouring location, pouring volume, and RMC material property retrieved from planning and ordering stage is suggested and proved through on-site verification. Through this, it is anticipated that it will be possible to secure the RMC quality by enabling RMC pouring planning centered on the construction site.
