されている。2. Description of the Related Art In recent years,
The concrete industry is said to be the representative of 3K (tight, dirty, dangerous), and among them, the environmental problem with noise is great. Therefore, studies have begun to improve fluidity and eliminate the need for a vibrator. However, simply adding water or a water-reducing agent to increase the fluidity causes material separation, the coarse aggregates are entangled with each other, the filling property is deteriorated, and uniform concrete cannot be obtained, resulting in a decrease in strength. For the purpose of suppressing this material separation, the addition of a water-soluble polymer and the blending of fine powder have been studied.

やすい。However, addition of a water-soluble polymer is indispensable because flowability and separation resistance cannot be satisfied only by adding fine powder (eg, Concrete Engineering Annual Papers, 1989.6, papers). No.1118 "Development of high performance concrete"). However, when a water-soluble polymer is added together with a dispersant which enhances fluidity, in many cases, it tends to interact with the water-reducing agent to hinder fluidity.

Therefore, it is extremely difficult to secure the desired viscosity and fluidity from these effects (for example, underwater concrete manual, 1987).
