Abstract
A method for treating aggregate to be used in cement is designed to perform surface treatment on aggregate by bringing fine bubble water containing fine bubbles into contact with the aggregate. The treated aggregate is used as a material for ready-mixed concrete to prepare concrete. The fine bubble water is produced by a high-speed swirling method, a pressure releasing method, or a combination thereof. The dispersibility of the aggregate is improved by the surface treatment.
Claims7
A method comprising:
- performing a surface treatment on aggregate for ready-mixed concrete, the surface treatment comprising:
- providing the aggregate, and
- bringing bubble water containing bubbles at a concentration of more than 0.1E08 pieces/ml into contact with the aggregate without using an air entraining (AE) agent and/or an AE water reducing agent;
- and
- removing the bubble water from the aggregate by evaporation or filtering.
