The application of HPC in Teks river Qapuqiha water conservancy project of Xinjiang

In this article,we using P.O32.5 cement in the locality,high quality fly ash and concrete admixture produced HPC,not only resolved corrosion by sulphate and durability in concrete of this project,but also saved a lot of fund for the project.Meanwhile,we researched that the high performance compensate the constringencies concrete produced with PO425 cement,silica fume,fly ash and added expansive agent and efficient water reducer,not only reduced crevice of concrete,but also improved abrasionresistant of concrete.We didn't found any harmful crevice in completed 300m long tunnel.
