Document Type and Number:
Japanese Patent JP3442067
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an abrasion-resistant pre-cast concrete member equipped with applicability and durability which is used for a civil engineering structure, and equipped with an abrasion-detecting means by which a replacement timing can be easily found even when the concrete member cannot withstand use any more by the abrasion due to the use over a long period of time.
SOLUTION: This abrasion-resistant pre-cast concrete member 1 for a civil engineering structure is used for repairing the civil engineering structure provided under a condition with severe abrasion, or the abraded section of an existing civil engineering structure and equipped with the abrasion-detecting means 13 which displays an allowable abrasion depth.
