摘要： A composition based on foamed perlite and magnesia cement for forming constructional thermo insulating elements and a method of making thereof.
The composition comprises additionally surface active substances such as methylcellulose, bentonite as swelling agent and H 3 PO 4 , NaH 2 PO 4 .2H 2 O and NH 4 H 2 PO 4 .
The made constructional articles have an even finely porous structure and can be easily machined or processed; they resist against passive flame and biologic agents, have antibacteric properties, are free of bad odours and do not emit environmental noxious substances.

摘要： Improved casing strings, and methods of using improved casing strings (4) in subterranean operations, are provided. An example of a method is a method of cementing a pipe string in a subterranean formation. Another example of a method is a method of cementing a pipe string in a well bore (10). An example of an apparatus is an improved pipe string comprising at least one pipe section; and a delivery system of an activator; wherein the delivery system of an activator is disposed adjacent an outer surface of the at least one pipe section.

摘要： The invention relates to a concrete, comprising a hydraulic binder, water, an aggregate, a mineral admixture and a chemical admixture acting as a superplasticiser, characterized in that said mineral admixture comprises colloidal silica and one or more of kaolin clay, metakaolin clay and montmorillonite clay with a blain value in the range of from 2000 to 8000 cm 2 /g, preferably from 3000 to 7000 cm 2 /g, more preferably from 3300 to 6000 cm 2 /g, still more preferably from 4000 to 5000 cm 2 /g. The invention also relates to a method for obtaining such a concrete, comprising the steps of: (a) mixing the hydraulic binder and clay; (b) adding a part of the water, in an amount sufficient to obtain an adequately manageable mass; (c) mixing said chemical admixture with said mass obtained in (b); (d) adding and mixing the collidal silica and the rest of the water with the mixture obtained in step (c); (e) mixing in the aggregates; and (f) hardening the mixture.

摘要： The invention concerns a method for preparing a blend consisting of power station ashes and/or slugs, and/or coal wastes in a quantity of 60-95% by weight, as well as an agglomeration promoting binder, including sewage after-fermentation sludge in a quantity of 5-40% in the dry state, said blend being so prepared that its total moisture contents is below 21%, and while maintaining features of a pourable material it can be homogenized in mixers provided with high speed rotary homogenizing means. After agglomerating said blend is fired in a rotary furnace. A firing method is characterized by that the rotary furnace operates with charge and gas phase moving in the co-current arrangement, what enables almost autothermal process with firing in the same time harmful volatile substances released from a binder. Said autothermal process is also promoted by the double-diameter structure of the furnace (a wider part 1A and a narrow par 1B), by its substantial slope, precise insulated heads 2 and 7, as well as gas ducts 3 and 14, and by dividing thee air stream, one part of which is directly supplied through the layer of the material being fired and sintered.

摘要： The invention relates to a sealing material used for building wells and filling underground hollow spaces, especially deep boreholes. Said sealing material comprises a predominant percentage of marl and a certain percentage of cement. In order to obtain durable and effective sealing of a groundwater horizon, an additional percentage of sand and an additional percentage of clay are admixed to the marl and the cement.
