control of the cracks of concrete reinforcement material

摘要

1. The technical field to which the invention described in the claims belongs;Regarding reinforcing materials for shrinkage / crack prevention of concrete.;2. Technical challenges to be solved by the invention;We intend to increase the strength of the concrete, improve the shrinkage / cracking inhibition rate, and prevent tangling when mixing in concrete.;3. The point of the solution of the invention;The tips (3) are formed at both ends of the body (2a) with a larger diameter than the body so as to be firmly embedded in the concrete (1) layer.;Then, the body 1a as the reinforcing material 2 is made to be somewhat rigid like a toothbrush of a toothbrush, and mixed in an even distribution without entanglement.;4. Important Uses of the Invention;For reinforcing concrete.
