Document Type and Number:

WIPO Patent Application WO/2015/045194

Kind Code:

A1

Abstract:

　The present invention provides a cement composition containing, at a minimum, blast furnace slag powder having an activity index, as defined in JIS A 6206 (the case of a 7-day material age, and Blaine's specific surface area of at least 3,500 cm2g but less than 5,000 cm2g), cement, limestone, and trialkanolamine. The present invention also provides concrete for construction in environments in which the daily average temperature is 23°C or above, wherein the concrete contains the aforedescribed cement composition, at a level of 200-400 kg per 1 m3 of the concrete.
