内容記述 |
Rock-Filled Concrete (RFC) is a new type of concrete which employs Self-Compacting Concrete (SCC) technology. RFC is produced by pouring ready-mixed SCC into the voids of large chunks of rock with the minimum size of 300 mm in a formwork. These large rocks are typically obtained near the dam sites without the need for crushing. The SCC fills the void space between the chunks of rock due to its good fluidity, and thereafter the mix sets to form the RFC mass. Various experiments had been carried out both in the laboratory and on the jobsite since it was first developed in 2003, demonstrating that RFC performed satisfactorily in the early stage and after hardening with regard to strength, permeability and thermal rising. Furthermore, the environmental impact assessments of RFC were also carried out by comparing it with conventional vibro-compacted concrete and Roller Compacted Concrete (RCC) in order to evaluate the social impacts. After two types of RFC construction technologies were developed, RFC has been employed in a number of hydraulic engineering structures in China. In this paper, based on the applications, a typical RFC construction system was described and the costs of RFC in these projects were assessed. All of the experiments and applications show that RFC had significant advantages in mass concrete construction, which indicates that RFC is potentially promising. |
