    摘要： The present invention discloses a method for ammonium-enhanced flue gas desulfurization (FGD) by using red mud slurry. The method specifically includes: crushing red mud, sieving the crushed red mud, slurrying the red mud, conducting aeration treatment, adding an ammonium salt and/or ammonia, and conducting natural sedimentation to obtain pretreated red mud slurry and pretreated red mud liquor; adding an ammonium salt and/or ammonia to the slurry, adding water and conducting uniform mixing, conducting pre-FGD, conducting deep desulfurization on treated flue gas by using the pretreated red mud liquor, and directly discharging desulfurized flue gas; and charging the pretreated red mud slurry and the pretreated red mud liquor obtained after the treatment to a replacement tank below, adding lime milk to the replacement tank, conducting stirring and natural sedimentation, conducting soilization on subnatant thick red mud slurry, and refluxing the supernatant to a red mud aeration tank.

    摘要： A quick hardening cement-asphalt composition used as a grout for a ballast-filled track structure comprising(a) 100 parts by weight of a cement composition prepared by adding to portland cement about 10 to 50% by weight of a mixture of a calcium aluminate-series mineral and calcium sulfate in a weight ratio of about 1:0.3 to 1:3; about 0.05 to 10% by weight of an inorganic salt, and about 0.05 to 3% by weight of at least one of an organic carboxylic acid, an organic hydroxycarboxylic acid and a salt thereof, and(b) about 30 to 400 parts by weight of an asphalt emulsion containing about 0.2 to 8% by weight of a polyoxyethylene alkyl phenyl ether, polyoxyethylene alkyl ether, polyoxyethylene alkyl ester, sorbitan alkyl ester, polyoxyethylene sorbitan alkyl ester or sucrose fatty acid ester nonionic emulsifier and about 0.05 to 2% by weight of a multivalent metal chloride, calculated as the multivalent metal ion.

    摘要： A grass sports ground is produced by mixing man-made vitreous fibres into soil having relatively high loam levels at a rate in the range 0.5 to 50 parts by weight per 100 parts soil (dry weight), preferably in the presence of moisture to separate the fibres and distribute them among soil particles, and then growing grass. The soil/fibre mixture has desirable moisture management properties as well as good mechanical characteristics providing extended use characteristics even in cold, wet or hot and dry conditions.
