This paper briefly discusses the history of the development of prestressed high-strength concrete (PHC) piles in China. It also includes the manufacturing technology and the important characteristics of the manufacturing process. Then we talk about the quality control and its level of raw material, concrete and the ultimate piles. The last part is the study and application of replacing part of the cement with ground ordinary building sand. Keywords: PHC piles, Manufacturing technology, Quality control, Autoclave curing, Centrifugal casting, Ground sand.
