Reinforcement material for preventing shrinkage cracking of concrete

摘要

1. TECHNICAL FIELD OF THE INVENTION;Concerning reinforcement for preventing shrinkage / cracking of concrete.;2. The technical problem to be solved by the invention;To increase the strength of concrete, improve the shrinkage / crack suppression rate and prevent it from getting tangled when mixing with concrete.;3. Summary of Solution to Invention;At both ends of the body 2a, a tip 3 was formed with a diameter larger than that of the body so that it was firmly embedded in the concrete 1 layer.;And the body (1a) to be a reinforcing material (2a) to be somewhat hard like the hair of the toothbrush to be mixed in an even distribution without entanglement during mixing.;4. Important uses of the invention;For concrete reinforcement.
