一、流态混凝土概要流态混凝土是一种利用高性能减水剂的优异水泥颗粒分散作用和减水作用而制取的具有大流动性和良好的施工性的混凝土。以往这类表面活性剂都是在搅拌混凝土时与其他材料同时加入搅拌器的。本文论述的流态混凝则是在混凝土搅拌完毕后再加减水剂以增大其坍落度。流态混凝土是联邦德国在七十年代初为改善低流动性混凝土的施工性而发展的,日本从1975年起
I. Summary of Fluidized Concrete Summary The fluidized concrete is a kind of concrete with high flowability and good workability, which is produced by excellent cement particle dispersion and water reduction using high-performance water-reducing agent. In the past, these types of surfactants were added to the stirrer at the same time as other materials were mixed with concrete. The fluid coagulation discussed in this paper is to add the water reducer to increase the slump after the concrete is stirred. Fluid concrete was developed by Federal Republic of Germany in the early 1970s to improve the construction of low-flow concrete. Japan began in 1975.
