摘要: It is an object of the present invention to provide a durability improving agent for a cement composition that improves the freezing-thawing resistance of the cement composition and also exhibits a sufficient shrinkage reducing performance as well, and a cement composition including such a durability improving agent. Specifically, the present invention provides a durability improving agent for a cement composition, characterized by comprising a hydrocarbon-based compound having an average molecular weight of 150 to 600 and a pour point of 20° C. or less as an active ingredient, and a cement composition including such durability improving agent.
