| Abstract: | Based on the optimization of material and proportion,adopting good powder of coal ash and fine grinding slag as admixture agent of mineral and high performance water reducing agent,using small percentage of water cement ration,C80 high-strength concrete may be manufactured successfully.This kind of concrete enjoys the following merits such as high fiuidity in workability,small percentage loss of slump and early extra strong in strength,and it adapts for the construction of high-rise buildings. |
