Title:
CEMENT COMPOSITION AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2017193473
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cement composition which can comparatively inexpensively suppress curing delay even when an admixture is used in cement using a large amount of blast furnace slag, and can effectively use the blast furnace slag having a low JIS basicity, and to provide a method for producing the same.SOLUTION: A cement composition contains a cement clinker and a high furnace slag, where a content of the high furnace slag is 60 mass% or more based on the total mass of the cement composition, a content of AlOin the high furnace slag is 13.75 mass% or more based on the total mass of the high furnace slag, and JIS basicity of the high furnace slag calculated by a method according to JIS A6206:2013 is 1.65 or more.SELECTED DRAWING: None
