A NOVEL SUPPLEMENTARY CEMENTITIOUS MATERIAL AND PRODUCTION METHOD THEREOF

摘要

The present invention proposes a novel supplementary cementitious material comprising an activated mixture having at least an activated clay-based material and an activated calcium-based material. Said activated mixture is obtained by subjecting a mixture of at least a clay-based material and a calcium-based material together into an activation treatment till 70-95 % of said calcium-based material is activated; wherein amount of the clay-based material in said mixture is minimum 70% by weight of said mixture, where said clay-based material contains clay source of at least 40% by weight; and amount of the calcium-based material in said mixture is between 10-30% by weight of said mixture, where said calcium-based material contains calcium source of at least 50 % by weight. The invention further proposes a method for producing SCM and a binder containing a mixture of said novel SCM with cement.
