In this article, authors introduce slow coherence prestress technology. By some tests, authors study some aspects of the technology, such as the selection of friction coefficient of slow coherence prestressed steel reinforcement, the bearing capacity of the prestressed beam. At last, the application of that technology in some projects is introduced.
