Crack induction structure using hardened body of organic fiber reinforced mortar

摘要

A crack induction structure is provided to satisfy the partial loss of area and the covering thickness and to control cracks in a structure, to reduce the number of cracks required for repair, and to have a waterproof effect by cutting off moisture permeated to the inside of a structure. A crack induction structure using an organic fiber reinforced mortar hardener for controlling cracks in a concrete structure is formed by installing organic fiber reinforced mortar hardeners(10), formed by mixing organic fiber to mortar and hardening in the shape of a pipe having a hollow inside, to the inside of a structure at regular intervals along the longitudinal direction of a structure to be perpendicular to the longitudinal direction of a structure, wherein crack induction grooves(20) are formed on the inner and outer surfaces of the concrete structure on which hardeners are installed to induce the crack formation of a wall.
