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.

Polycondensation product based on aromatic compounds, method for the preparation and use thereof

The invention relates to a method for grinding an inorganic solid from the series cement clinker, pozzolan and/or raw material for cement production, where a grinding additive is added before or during grinding, and the grinding additive, based on the dry mass, comprises 6% to 80% by weight of caprolactam and 1.5% to 30% by weight of aminocaproic acid, where, based in each case on the dry mass, 0.002% to 2% by weight of the grinding additive is used, based on the total solid. Further claimed are a grinding additive and the use thereof for increasing the compressive strength of the cured product produced therewith.

Grinding additive for mineral binders

The invention relates to a method for producing a hydraulic binder, comprising contacting a composition comprising cement clinker, before, during or after the grinding procedure, with (a) a defoaming agent and (b) 0.0005% to 2% by weight, based on the total composition, of at least one air-introducing compound, the defoaming agent (a) comprising 0.0001% to 0.5% by weight, based on the total composition, of at least one defoaming agent of the formula R&#x2014;(CH&#x2014;O&#x2014;)&#x2014;(CH&#x2014;O&#x2014;)&#x2014;H and the ratio of (a) to (b) being between 1:1 to 1:200.

Process for manufacturing a hydraulic bonding agent, corresponding additive and its use

In the thermoelectric module composed of p- and n-conductive thermoelectric material legs which are connected to one another alternately via electrically conductive contacts, at least some of the electrically conductive contacts on the cold and/or the warm side of the thermoelectric module are formed between, or embedded into, the thermoelectric material legs composed of porous metallic materials.

Use of porous metallic materials as contact connection in thermoelectric modules

A cementitious material manufactured by a process including adding, after pyroprocessing, at least one desugared molasses to at least one cementitious and/or pozzolanic material during manufacture of the at least one cementitious and/or pozzolanic material. A method of manufacturing a cementitious material including adding, after pyroprocessing, at least one desugared molasses to at least one cementitious and/or pozzolanic material during manufacture of the at least one cementitious and/or pozzolanic material.

Cement additive

The use of induction furnaces for producing thermoelectric legs and components for thermoelectric modules is described, as is a process for producing thermoelectric semiconductor materials by co-melting mixtures of the particular element constituents of the thermoelectric semiconductor materials or alloys thereof in an induction furnace and pouring the melt thus obtained into the mold of a thermoelectric leg, or spraying the melt thus obtained to produce a pulverulent thermoelectric semiconductor material.

Process for producing thermoelectric semiconductor materials and legs

A method for applying at least one layer, selected from diffusion barriers, further protective layers, adhesion promoters, solders and electrical contacts, onto thermoelectric materials, is characterized by the fact that the at least one layer is rolled or pressed onto the thermoelectric material at a temperature at which the thermoelectric material is flowable.
