| Abstract: | This paper proves by experiment that C50 high strength high performance concrete can be also prepared with local raw material in Zhangzhou and super water-reducing agent, first-class fine coal ash. Cement consumption is limited less than 425 kg/m3. Slump of prestressing concrete is limited within 50 mm - 70mm and shlmp of pumping concrete is limited from180 mm to 160mm. |
