摘要：

Low-plastic porous cement concrete, a high-fluid porous cement concrete, is doveloped for special requirements of base construction in urban highway. The paper presents the strength standard of design and suggested gradation for the low-plastic porous cement concrete, and also a discussion of the molding method of sample in the laboratory. When designing the low-plastic porous cement concrete, many factors should be considered such as fly ash addition, efficient water reducing agent addition and water-cement ratio and so on. An analysis is made of the effect of these factors on the slump, void and strength of low-plastic porous cement concrete. Based on the research, the component of low-plastic porous cement concrete is proposed.
