Document Type and Number:
Japanese Patent JP4104303
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for determining the composition of concrete which can produce concrete capable of smoothing concrete placing work including the conveyance, charge, compaction, and leveling of concrete by using the crushed pieces of concrete blocks obtained when an existing concrete structure is disassembled. SOLUTION: In the method, the crushed pieces of cured concrete comprising a fine particle portion, a small particle portion, and a coarse particle portion are used as aggregate. The composition of concrete is determined so that the content of the coarse portion does not exceed the first standard value, and the content of a paste portion comprising water, cement, and the fine particle portion excluding cement is at least the second standard value.
