用粉煤灰配制高性能泵送砼，着重研究拌合料坍落值（ＳＬ）粘度流下值（Ｔ）及砼的扩展度（Ｄ），使结果拌合料的可泵性改善，增加了砼流变性，满足了砼设计要求。
The fly ash is used to prepare high-performance pumping concrete, and the value of viscosity (T) and expansion (D) of the slump value of the mixture are mainly studied to improve the pumpability of the resulting mixture and increase Concrete rheology, to meet the concrete design requirements.
