水工特细砂泵送混凝土力学特性试验研究

近年来,在一些中、粗砂资源逐渐匮乏的地区,使用特细砂拌制水工混凝土成为节约资源、降低成本的重要途径.鉴于国内目前对特细砂泵送混凝土力学性能缺乏研究,为了推广应用特细砂泵送混凝土,通过确定了以特细砂泵送混凝土力学特性为研究对象,从特细砂泵送混凝土各材料用量角度研究配制参数对混凝土抗压强度的影响,从中找出各个材料用量对抗压强度的影响规律,为特细砂泵送混凝土配合比设计提供了数据支持.并在试验的基础上将其应用于工程中.

Test research and project application of hydraulic superfine sand pump concrete

In recent years,in some areas,where the coarse sand resources are deficient,the superfine sand is mixed into the hydraulic concrete gradually,and it becomes an important way to save resources and reduce the cost.In view of the fact that the less research on the mechanical performance of superfine sand pump concrete is in our country,in order to promote and apply superfine sand pump concrete,the mechanical performance of superfine sand pump concrete is studied.From various materials amount used,the influence...
