| 摘 要： | 经大量实践证明，同时具有良好的和易性及强度的流态混凝土，其水泥浆体积与集料体积之比常常为35：65，即Ve:(Vs Vg)=35:65，在此事实基础上，结合我国有关粉煤灰混凝土设计规范，提出一种流态粉煤灰混凝土配合比的设计方法，它不仅容易掌握，而且可以大幅度地降低该类混凝土的生产成本，因此具有应用推广价值。

| Abstract: | it has been proved by means of a great deal of practical experience that the volume ratio of cement paste to aggregate, for flowable concrete with high strength and high flowability, is always equal to 35:65, i.e. Ve:(Vs+Vg)=35:65. Based on this fact and refer to our country's design standard for fly-ash concrete, a method of proportioning the flowablw fly-ash concrete has been proposed, which is not only easy to be master, but also able to greatly reduce the cost of concrete. |
