流化剂或高效能减水剂是配制流态混凝土的关键材料。但是,要配制流态混凝土,还必须解决工艺中的技术关键,也就是流化剂的后添加、反复添加及其流态化作用。在商品混凝土搅拌站,生产预拌混凝土时,同时加入流化剂或高效能减水剂,配制不了满足现场泵送施工的流态混凝土,而必须把预拌混凝土经过一段时间
Fluidizers or high-performance water-reducing agents are key materials for the formulation of fluid concrete. However, in order to prepare the fluid concrete, it is also necessary to solve the technical key in the process, that is, the post-adding of the fluidizer, repeated addition and fluidization. In the commercial concrete mixing station, when the ready-mixed concrete is produced, fluidizing agent or high-efficiency water-reducing agent is added at the same time, the fluidized concrete that cannot meet the site pumping construction cannot be prepared, and the ready-mixed concrete must pass through for a period of time.
