摘要： Systems, methods, and apparatus for producing wellbore fluids using drill cuttings, geopolymers, and/or mine tailings, and compositions relating to the same are disclosed. The drill cuttings, geopolymers, and/or mine tailings may be used to create appropriate wellbore fluids to be used in wellbore fluid supply systems, such as spacer fluids, lead barrier fluids, tail barrier fluids. In one embodiment, the wellbore fluids result in one or more substantially impermeable barrier sheaths within the wellbore, which barrier sheaths may be cementitious or non-cementitious.

摘要： A method for converting a starting material containing at least 40 wt.-% of calcium silicon (hydr)oxide phases and calcium aluminum (hydr)oxide phases into an SiO2 rich SCM and a calcium carbonate additive includes the steps: providing the starting material with a D90 of ≤1 mm, mixing the starting material with water or adjusting the water content to provide a starting material slurry having a solid:liquid weight ratio from 2:1 to 1:100, passing the starting material slurry together with carbon dioxide into a gravity separation reactor, subjecting the starting material slurry and carbon dioxide to centrifugal motion inside the reactor, and removing a heavy slurry from a first outlet of the reactor, removing a light slurry of lower density particles from a second outlet of the reactor, and removing liquid at a third outlet of the reactor.

摘要： Disclosed herein are improved methods for recycling used engine oil (UEO). The method includes steps of, mixing UEO, a superplasticizer, and water to give a suspension; mixing aggregates, ordinary Portland cement (OPC), fly ash, silicate fume, and the water to give a first mixture; adding the suspension to the first mixture to give a second mixture; and molding and curing the second mixture into a concrete. The thus produced concrete contains up to 5% of UEO (by weight of total cementitious material) and exhibits comparable compressive properties as to that of ordinary concrete.

摘要： Provided herein are cementitious materials, for example, a crack-resistant cementitious mortar. The cementitious materials are a mixture of cement, at least one recycled fiber reinforcement material, a recycled aggregate material, and water. Also provided is a method for increasing the crack-resistance of a cementitious material by replacing the sand in a cement mortar with a recycled aggregate material and adding at least one recycled fiber reinforcement material and a volume of water.

摘要： A method for recycling a used rotor blade of a wind turbine includes processing the used rotor blade into a plurality of material fragments. The method also includes treating the plurality of material fragments to remove at least a portion of the at least one composite material and expose the at least one fiber material of the used rotor blade. Further, the method includes mixing the treated plurality of material fragments with, at least, an alkali activator to form a usable geopolymer concrete.

摘要： The present invention describes a method for manufacturing of a composite fixated material comprising the steps of: (a) providing bottom oil shale ash obtained after burning oil shale, said bottom oil shale (BOSA) comprises pozzolanic particles having size of about 10 to 4000 μm and being capable of adsorbing trace elements at their surface; (b) providing acidic waste comprising said trace elements; and (c) adding the BOSA provided in step (a) to the acidic waste provided in step (b) in amount of about 0.1-0.4 weight parts of said BOSA per one weight part of said waste, and mixing said waste with said BOSA, thereby obtaining a neutralised (scrubbed) precipitate with the fixated trace elements, wherein said neutralised (scrubbed) precipitate with the fixated trace elements constitutes said composite fixated material.
