RECYCLED CONCRETE AND ITS PRODUCTION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a recycled concrete production process for producing recycled concrete having high strength and excellent durability from concrete lumps discharged when demolition or the like of a concrete structure is performed, without subjecting the concrete lumps to any advanced treatment, and also to provide such recycled concrete which is produced by the production process and can effectively be reutilized. SOLUTION: This recycled concrete consists of a number of concrete lumps obtained when an existing concrete structure is demolished, and joint concrete which is used for filling the spaces among the concrete lumps and contains coarse aggregate.
