This invention relates to environment-friendly cement comprising an active filler (1), an inert filler (2) and a sodium metasilicate aqueous solution (3); the active filler (1) comprises heat insulation asbestos and a waste material of wastes of the heat insulation asbestos; the insert filler (2) comprises metakaolin and aggregates such as furnace slag and organic resin selected from cement, fine sand, gravels and wastes to be solidified according to circumstances; and the sodium metasilicate aqueous solution (3) is used as an alkaline compound. This invention also relates to a production method of the environment-friendly cement, and the production method comprises the steps: respectively mixing the component (1) with the component (3) and mixing the component (2) with the component (3), dissolving out elements of silicon and aluminum in the component (1) by virtue of the alkaline solution serving as the component (3) by mixing after respectively obtaining slurry A and slurry B, and then, mutually bonding si
