Title:
NONWOVEN FABRIC MAT HAVING HIGH RIGIDITY FOR REINFORCING HYDRAULIC SUBSTANCE
Document Type and Number:
Japanese Patent JP3839698
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a nonwoven fabric mat having high rigidity for reinforcing a hydraulic substance which can easily be installed and makes a concrete structure strong and rigid when used as a reinforcing material for repair and reinforcement of the hydraulic substances such as cement which is a brittle material.
SOLUTION: The nonwoven fabric mat comprises an organic synthetic fiber A and an organic synthetic fiber B which have different fiber physical property to each other. The organic synthetic fiber A and the organic synthetic fiber B are in a weight ratio of A:B=80:20-20:80, and this nonwoven fabric mat has a bulk specific gravity of 0.008-0.018 g/cm3 and is used for repair and reinforcement of the hydraulic substance, the destruction strength of the hydraulically cured material containing the nonwoven fabric mat is larger than an initial crack strength.
