ENVIRONMENTALLY FRIENDLY CEMENT AND PRODUCTION METHOD THEREOF
An environmentally friendly cement comprises (1) an active filler comprising waste materials composed of a thermal insulation wool and a waste thereof; (2) an inert filler comprising metakaolin and an aggregate optionally selected from cement, fine sand, gravel, waste to be solidified, and organic resin; and (3) an aqueous solution of sodium metasilicate as an alkaline compound. A method for producing the environmentally friendly cement comprises mixing ingredients (1) and (3) and ingredients (2) and (3) respectively to obtain a slurry A and a slurry B respectively; mixing the slurry A and B; and hardening the final slurry, whereby elements silicon and aluminum in the ingredient (1) are dissolved out in the basic solution of the ingredient (3), and a closed framework structure is formed by bonding silica and alumina as tetrahedrons. The environmentally friendly cement has excellent fire tolerance, heat insulation, acid and alkaline resistance, and mechanical properties.
