NOVELTY - An environmentally-friendly silicate cement comprises 20-40 pts. wt. silicate cement clinker, 20- 40 pts. wt. fly ash, 50-70 pts. wt. slag, 40-60 pts. wt. coal gangue, 10-20 pts. wt. trisodium citrate, 8-12 pts. wt. desulfurized gypsum, 5-10 pts. wt. superfine zeolite powder and 15 -20 pts. wt. mineral powder. USE - Environmentally-friendly silicate cement used in civil construction, water conservancy, national defense and other engineering applications. ADVANTAGE - The ecological silicate cement has high anti-folding strength of 65 MPa and 10.1 MPa, lowest abrasion loss of 1.7 kg/m2, highest cement slurry fluidity of 269 mm, and has improved strength with high compatibility. The added fly ash, slag and coal gangue can fully utilize the industrial waste residue, saves the environment resource, and realizes the resource production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the environmentally-friendly silicate cement.
