ANTI-CAKING AGENT OF GRANULATED BLAST FURNACE SLAG OR PARTICLE SIZE REGULATED MATERIAL THEREOF, CAKING PREVENTION METHOD AND FINE AGGREGATE FOR HYDRAULIC CEMENT COMPOSITION
Document Type and Number:
Japanese Patent JP3914123
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an anti-caking agent sufficiently preventing the caking of granulated blast furnace slag or the particle size regulated material over a long period, a method of preventing the caking and fine aggregate for a hydraulic cement composition which is capable of suppressing the occurrence of bleeding in the prepared hydraulic cememt composition in the preparation of the hydraulic cement composition using the granulated blast furnace slag or the particle size regulated material as the fine aggregate.
SOLUTION: As the anti-caking agent for the granulated blast furnace slag or the particle size regulated material thereof, a specific acrylic acid-based polymer and one or more materials selected from gluconic acid, a salt of gluconic acid, an ethylene oxide adduct of gluconic acid, a salt of the ethylene oxide adduct of gluconic acid and an ethylene oxide adduct of the salt of gluconic acid are used.
