一、流动混凝土的由来和发展所谓流动混凝土,就是用搅拌车将常规办法制成的有一定坍落度的混凝土拌和物(称为基准混凝土)运至现场,在浇筑前加入一定数量的流化剂(高效能减水剂),经二次搅拌制成均匀流动化的混凝土。它的主要特点是:不增加用水量,保持干稠混凝土的 First, the origin of the flow of concrete and the development of the so-called flow of concrete, is to use a mixer truck to make a certain degree of slump in the concrete mixture (referred to as the benchmark concrete) to the scene, add a certain amount of fluidization before pouring The agent (high-efficiency water reducer) is made into a uniform fluidized concrete by secondary stirring. Its main features are: no increase in water consumption, keeping dry thick concrete
