泵送混凝土除对水泥、粗、细管料的质量与规格有严格要求外，配合比设计是保证混凝土质量的关键，文中对用绝对体积法进行配合比设计的方法做了实例介绍，应用文中所述方法设计的泵送混凝土，均可达到不渗、不裂、保证强度、且泵送顺利。

In addition to the requirements of quality and specificatlons for the cement, coarse and fine aggregates ofpumping concrete, the design of mix proportion is the key point to control concrete quality. This paper intro-duces a case history of the design of the mix proportion using absolue volume method. The pumping concrete de-signed by the method expounded in this paper has no permeability, no cracking, ensuring strength and smoothpumping.
