Abstract: An activator composition for a non-OPC hydraulically-active material comprises CaO or lime and a polycarboxylate-ether-based (PCE) superplasticiser, and is mixable with a hydraulically active material comprising ground granulated blast furnace slag (GGBS) and/or pulverized fuel ash (PFA) to form a cementitious binder. The cementitious binder does not comprise any Portland cement and is, therefore, more environmentally friendly.

Abstract: A drilling fluid composition which includes a base fluid, one or more additives, and a viscosifier package. The base fluid is an invert emulsion comprising oil and water. Further, the one or more additives is chosen from an emulsifier, a weighting material, a fluid-loss control additive, or an alkaline compound. The viscosifier package includes a fatty acid having 6 or more carbon atoms and an aliphatic polyester. The drilling fluid composition has a yield point of from 30 lbf/100 ft2 to 100 lbf/100 ft2 and a low shear yield point of from 10 lbf/100 ft2 to 40 lbf/100 ft2.

Abstract: The present invention relates to copolymers that comprise salicylic acid derivative structural units and structural units having free polyether side chains. The copolymers are suitable to plasticize inorganic binder systems, construction chemical compositions comprising said copolymers and the use of said copolymers as a plasticizer for inorganic binder systems. Binder systems with a reduced amount of Portland cement comprising at least one copolymer of the invention provide a better liquefaction and processability as compared to said binder systems without a copolymer of the invention.

Abstract: A method for preparing ceramsite by using municipal sludge as raw material, including the following specific steps: drying; preparing ingredients including raw sludge, fly ash, kaolinite, steelmaking slag, zeolite, hematite, calcareous shale, waste incineration fly ash, Fe2O3, waste glass, calcium carbonate, sodium lauryl sulfate, and sodium benzoate; mixing and stirring uniformly, and putting the stirred materials into a granulating machine for granulation; drying and preheating the material pellets after granulation, and then quickly transferring to a sintering device for first sintering at a low temperature and then sintering at a high temperature; crushing large chunks of the cooled materials; and separating and screening the crushed materials. The method of the present invention reduces the generation of the large chunks of the cooled materials in the obtained ceramsite, thereby reducing the subsequent crushing work and saving energy consumption accordingly.
