Title:
セメントクリンカ及びセメント組成物
Document Type and Number:
Japanese Patent JP4164240
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cement clinker having stable quality even using a large amount of an industrial waste consisting essentially of SiO2 and Al2O3 as raw materials, and to a provide a cement composition using the cement clinker. SOLUTION: The cement clinker uses the industrial waste consisting essentially of SiO2 and Al2O3 as raw materials and has a hydraulic modulus(H.M.) of 1.8-2.3, a silica modulus(S.M.) of 1.3-2.3 and an iron modulus(I.M.) of 1.3-1.8. In the cement composition, gypsum is mixed to the cement clinker so that a total amount of SO3 is 2.0-5.0 wt.% and the resultant mixture is pulverized or they are separately pulverized and then mixed.
