Title:
CRACK SUPPRESSION MATERIAL FOR CEMENT HARDENED BODY, CEMENT HARDENED BODY AND MANUFACTURING METHOD OF THE CEMENT HARDENED BODY
Document Type and Number:
Japanese Patent JP2009126730
Kind Code:
A
Abstract:

To provide a technology capable of realizing crack suppression in concrete etc. at a low cost.

A crack suppression material for a cement hardened body is a net-like body wherein a first yarn and a second yarn shorter than the first yarn are combined in a net-like form. Here, the ratio of the tensile stiffness of the first yarn to the tensile stiffness of the second yarn is 1.5-30.
