Abstract
The invention discloses a magnesium slag compound silicate hydraulic cementing material. The preparation method is as follows: the materials which are matched by weight shares as follows: 41 to 55 shares of magnesium-smelting reduced-slag, 15 to 33 shares of silicate cement grog, 1 to 8 shares of gypsum and 5 to 20 shares of fly ash or cinder, or/and granulated blast-furnace slag are mixed and then milled into thin powder which is directed processed into the hydraulic cementing material which takes the magnesium slag compound silicate as a main content and can be directly used for construction and reaches the 'compound silicate cement' standard. The invention can directly lead the reduced slag generated during magnesium smelting by heat-reduction method to be converted into the hydraulic cementing material used for construction so as to recycle the wastes, reduce the contamination to environment by the magnesium-reduction waste slag and reduce the cost of disposal of waste slag.
