一、前言所谓流态混凝土,一般的定义是,在坍落度为5～8厘米的基准混凝土拌和物中掺入一定量的高性能流动化剂,在几分钟的继续拌和中使坍落度显著增大至20厘米以上的大坍落度混凝土。它是一种既能流动自密而又不失塑性混凝土通常性能的新型混凝土。
I. INTRODUCTION The so-called fluidized concrete is generally defined as a mixture of a certain amount of high-performance fluidizing agent in a reference concrete mix with a slump of 5 to 8 cm, and slump in a few minutes of continuous mixing. Significantly increase the slump concrete to more than 20 cm. It is a new type of concrete that can flow self-contained without sacrificing the usual properties of plastic concrete.
