基于粉煤灰掺量的双掺混凝土配合比设计

Fly ash-based dual-mixed concrete mix design

以基准混凝土的配合比设计为起点,直接借鉴和借助普通混凝土配合比设计的大量技术资料,已掌握的混凝土技术法则及长期的丰富经验,研究探讨粉煤灰双掺混凝土中各组成材料用量,进而得到较合理的配合比,并给出了粉煤灰掺量与混凝土强度关系的拟合曲线,以便用于指导工程应用。

The base concrete mix design as a starting point,draw on and use of ordinary concrete mix design for a large number of technical in- formation,the available concrete technology law and long-term experience in research and discuss the fly ash mixed concrete,the constituent ma- terials consumption and thus get a more reasonable mix and gives the fly ash and concrete strength of the relationship between the fitting curve in order to be used to guide engineering applications.
