Proposed is a polycondensation product comprising as monomer components at least one aryl polyoxyalkylene ether, at least one vicinally disubstituted aromatic compound, at least one aldehyde and also optionally further aromatic compounds; processes for preparing same, and also use thereof as dispersant for aqueous suspensions of inorganic binders and as grinding assistant for inorganic binders.

The present disclosure describes compositions (bio-carbon materials) and methods of making compositions that comprise a binder (such as a phenolic binder which may comprise cardanol) and charcoal, preferably in a powder form. The composition may also include an accelerator/catalyst. The binder, charcoal powder, and accelerator may be mixed together, formed (pressurized, rolled, or extruded) and then cured. The resulting composition may be used as a metallurgical reducing agent, processed into anodes for use in the metallurgical industry, used in the construction industry for example as an ingredient in concrete, and as a fuel for cooking.

A formulation containing polymer, resin and cement combined with aggregate can be used as a gunnable mix that is applied to a surface by being conveyed pneumatically in dry form to a nozzle, where water is added. Polymer in the gunnable mix enables it to adhere and bond to a surface, such as carbon brick, of a lining of a vessel used for the containment of molten metals. The formulation may be used, for example, to repair and protect blast furnace hearth linings.

A polycondensation product containing a phenolic copolymer useful for a hydraulic-composition dispersant that has stable dispersability and can obtain a prescribed fluidity, including a copolymer obtained by polycondensing a monomeric mixture including compounds A-D of formulas (A)-(D). A hydraulic-composition dispersant containing the product or copolymer. In the formulas, A1O, A2O, A3O, and A4O represent a C2-4 alkylene oxide group; m, n represent a number from 0 to 300 and m+n1; p, q represent a number from 1 to 300; X represents a hydrogen atom, alkyl group, or C1-24 acyl group; R0, R1 represent a hydrogen atom, alkyl group or alkenyl group; Y1, Y2 represent a hydrogen atom, phosphoester group, or sulfate ester group; Y3 represents a phosphoester or a sulfate ester group; R2 represents a hydrogen atom, carboxyl group, C1-10 alkyl group, C2-10 alkenyl group, phenyl group, napthyl group, or heterocyclic group; r represents a number from 1-100.

Plastomer-modified asphalt binders meeting MSCR specifications, asphalt paving materials with such asphalt binders, and methods for fabricating such asphalt binders are provided. The asphalt binder contains a base asphalt and a plastomer. If the plastomer has a drop point no greater than about 139 C., the asphalt binder further contains sulfur; sulfur-containing compounds, such as hydrocarbyl polysulfides and thiuram disulfides; phenolic resins; metal oxides; or a combination thereof. The asphalt binder is substantially free of elastomer.
