所谓流态混凝土,就是在预先拌好的单位用水量小的干硬性和低塑性混凝土中,加入能使水泥颗粒分散性能提高的外加剂(高效减水剂)制成的流动性良好的大坍落度混凝土。流态混凝土于1971年在西德为改善干硬性混凝土的施工性能而研制成功,1974年编制了流态混凝土的制造和施工指南。1976年英国水泥混凝土协会和水泥外加剂协会共
The so-called fluidized concrete is a good fluidity product made of an admixture (high-efficiency water-reducing agent) capable of improving the dispersibility of cement particles in a pre-mixed dry hard and low plastic concrete with a small amount of water used per unit. Gradient concrete. The fluid concrete was successfully developed in West Germany in 1971 to improve the performance of dry hard concrete. In 1974, a guide for the manufacture and construction of fluid concrete was developed. 1976 British Cement Concrete Association and Cement Admixture Association
