Abstract: Novel composites having improved performance such as compressive and/or tensile strengths are formed from carbon-based nanomaterials and a binder. Sheared carbon-based nanomaterial in solution is typically mixed with a binder and then cured. The composites may have several improved properties such as higher compressive strength, tensile strength, lower shrinkage, and modified viscosity which are greater than the binder alone.

Abstract: A concrete composition for use in construction that is free of cement includes calcium sulfate hemihydrate (CSH), polypropylene (PP) fiber, sand, retarders, and superplasticizers. The retarders include poly condensed amino acid and calcium (Ca) salt. The superplasticizers include specially formulated polycarboxylate powder. Further, a method of using the concrete composition in one or more construction related activities (e.g., architectural applications) includes adding the concrete composition to water in a mixer, the concrete composition including CSH, PP fiber, sand, a retarder, and a superplasticizer; and blending the concrete composition with water in the mixer for a first predetermined amount of time. The method further includes mixing the concrete composition with water at a predetermined sheer in the mixer for a second predetermined amount of time. The method excludes the steps of steam curing, accelerated curing, and water curing that are used in conventional solutions.

Abstract: Method of efficiently manufacturing cement-SCM compositions having improved strength compared to cement-SCM compositions made using conventional methods. The cement-SCM compositions may contain: (A) a fine interground particulate component with (1) a hydraulic cement fraction and (2) a supplementary cementitious material (SCM) fraction; (B) a coarse particulate component comprised of coarse SCM particles not interground with the fine interground particulate component; and optionally (C) an auxiliary particulate component not interground with the fine interground particulate component or the coarse particulate component. A method of manufacturing a cement-SCM composition may be performed by: (A) intergrinding hydraulic cement (e.g., cement clinker) with one or more SCMs to form a fine interground particulate component; (B) blending, without intergrinding, the fine interground particulate component with a coarse particulate component comprised of coarse SCM particles; and optionally (C) further combining, without intergrinding, an auxiliary particulate component with the fine interground particulate component and the coarse particulate component.

Abstract: A carbonation-resistant cementitious blend containing cement, an expandable agent present, a dispersion agent, a fluid loss additive, a defoamer, and an olive waste. Concrete samples made therefrom and methods of producing such concrete samples are also specified. The addition of olive waste provides enhanced durability (carbonation resistance) and maintains mechanical strength (e.g. compressive strength, tensile strength) after exposure to CO2 and/or brine. The resulting concretes are suitable cementing material for oil and gas wells as well as wellbores for geologic carbon sequestration.

Abstract: The invention provides a high temperature resistant Portland cement slurry and a production method thereof. The high temperature resistant Portland cement slurry comprises the following components by weight: 100 parts of an oil well Portland cement, 60-85 parts of a high temperature reinforcing material, 68-80 parts of fresh water, 1-200 parts of a density adjuster, 0.1-1.5 parts of a suspension stabilizer, 0.8-1.5 parts of a dispersant, 3-4 parts of a fluid loss agent, 0-3 parts of a retarder and 0.2-0.8 part of a defoamer. The high temperature resistant Portland cement slurry has a good sedimentation stability at normal temperature, and develops strength rapidly at a low temperature. The compressive strength is up to 40 MPa or more at a high temperature of 350° C., and the long-term high-temperature compressive strength develops stably without degradation. Therefore, it can meet the requirements for field application in heavy oil thermal recovery wells, reaching the level of Grade G Portland cement for cementing oil and gas wells.
