TREATMENT OF BROKEN CONCRETE FOR REUTILIZATION

摘要

PURPOSE:To effectively reutilize concrete produced by pulling down a concrete structure as part of a new concrete structure by removing foreign matter from the concrete, mixing the concrete with mortar and solidifying the mixture. CONSTITUTION:Concrete 3 produced by pulling down the concrete structure 1 of a nuclear power plant or the like is thrown into a hole 2 excavated in the ground of a site adjacent to the site of the structure 1. Cement mortar 6 manufactured in a mortar plant 4 is injected into the gap in the laid broken concrete 3 by a pump and solidified to reutilize the concrete 3 as the foundation 8 of a new concrete structure 9 and part of the structure 9. The trouble of transporting and dumping the broken concrete to a distance is saved and the cost of construction of the new concrete structure is reduced.
