泵送砼作为一项全新的施工工艺，日益显示出其高质高效的特点，但是，由于有的施工人员对该工艺的一些要求缺乏系统了解，而应用一些传统操作方法，致使施工中时常发生泵送故障和才质量问题，影响了泵送工艺的推广。 在砼中，水、水泥和砂形成水泥砂浆，均匀包在粗骨料表面，并 As a brand-new construction process, pumping concrete has increasingly demonstrated its high quality and high efficiency. However, due to the lack of systematic understanding of some requirements of the process by some construction personnel, some traditional operating methods are applied, resulting in frequent occurrence of construction. Pumping faults and quality problems have affected the promotion of pumping technology. In the concrete, water, cement and sand form a cement mortar and evenly cover the surface of the coarse aggregate.
