During the past 50 years, China have gained unprecedented achievements in construction industry. As one of the main structural styles, concrete structures are extensively used in various fields of building and civil engineering, which has made a great contribution to construction of infrastructures in China. Author mainly summarizes the developments of concrete science and technology in our country since 1949, particularly in recent 20 reforming and opening years. The successes of advanced concrete technique applied to high-rise building, long span structure and other large-scale structure are developed. Moreover, the development of design theoriy and Chinese design codes of concrete are briefly explained.
