UEA微膨胀混凝土在超长钢混结构中的运用

以某工程施工采用UEA微膨胀混凝土一次性无缝施工技术为例,介绍了该技术的原理,对膨胀混凝土配合比的确定及拆模等施工要点进行了阐述,实践证明该技术的运用加快了工程进度,提高了经济效益,值得推广应用。

On application of UEA slight expansion concrete in super-long steel-concrete structure

Taking the adoption of the UEA slight expansion concrete disposable jointless construction technique in some project as the example,the paper introduces the principle of the technique,illustrates some construction points,including the identification of the mix proportion of the expansion concrete and the form removal,and proves by the practice that the technique can accelerate the engineering progress and improve the economic benefits,so it should be further applied.
