摘要:
Gezeigt und beschrieben wird ein gefüllter, porosierter, gebrannter Tonziegel (1) mit Hohlräumen (2). Die Hohlräume (2) (Kammern) sind mit einem zementgebundenen Altpapierbrei (3) gefüllt und es liegt nach der Trockenzeit ein kompakter, stabiler Baustein vor.
摘要:
A lost circulation material and method for well treatment employing the material that is effective at sealing or plugging fractured zones and has utility over a wide range of temperatures, including high temperatures. The lost circulation material includes particulate material to quickly de-fluidize the fluid formulation, fibrous material to suspend particles in the slurrified form of the composition and increase the shear strength of the resultant seal, and non-Portland cement material for increasing the compressive strength.

"GEOPOLYMER CEMENT MADE FROM RECYCLED GLASS AND ITS MANUFACTURING PROCESS", the present invention relates to a geopolymer cement from recycled glass and its manufacturing process that, according to its characteristics, can produce geopolymer cement in its own and specific binding structure of a rigid solid type, made from recycled glass (waste), alkalis and water, and obtained directly by milling, homogenization, alkalinization and curing at room temperature, or forced curing of its components, and it can be used, in an extremely convenient, safe and cost-effective manner, as a new geopolymer matrix to replace the traditional ones made from metakaolin, blast furnace slag, fly ash or volcanic rock in various applications - to manufacture cement slabs, concrete, fiber composites and materials for coatings, aligned with an eco-friendly concept for complete reuse of this waste which is disposed in the environment.
摘要:
The invention relates to a viscoelastic material characterised in that it is produced by recovery of the hydrophobic phase obtained by a method of hydrothermal liquefaction from a biomass comprising at least one microalga and comprising at least 40 wt.% of water in relation to the total weight of the biomass, said hydrophobic phase comprising a viscoelastic oil and solid residues, wherein the quantity of solid residues amounts to between 15 wt.% and 30 wt.% of the total weight of the hydrophobic phase.
