ミキサの種類と練りまぜ時間がコンクリートの品質に及ぼす影響

抄録

When concrete is mixed by a mixer, properties of concrete, such as a slump, bleeding ratio, compressive strength, etc., change as mixing time increases. As these properties of concrete differ not only by the mixing time but also by the type of mixer used, the same properties of concrete cannot be obtained at the same mixing time even when the mix proportion is the same. This paper clarifies that the condition to obtain the same properties of concrete using different type of mixer is to mix concrete with the same energy consumption of the mixer measured by means of electricity.
