Title:
HYDRAULIC COMPOSITION
Document Type and Number:
Japanese Patent JP2014097918
Kind Code:
A
Abstract:

To provide a hydraulic composition capable of increasing used amount of waste compared with that in the case of conventional cements, excellent in strength generation property by using a clinker capable of reducing firing temperature during manufacturing.

A hydraulic composition contains a cement clinker having the total amount of C3A and C4AF calculated by the Bogue equation of 22% or more, the amount of C3S of 60% or more and iron modulus (I.M.) of 1.3 or less, gypsum and lime stone of 5 mass% per the whole composition as a mixed material. More excellent strength generation property than the case without addition of the mixed material is obtained. It is further preferable to contain a blast furnace slag.
