  • Surface treatment method for sand aggregate and method for producing ready-mixed concrete
    Patent number: 11345635
    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.
