摘要： Vinyl acetate-ethylene and/or styrene-(meth)acrylic ester copolymers along with processes for preparing the same and uses for the same. Wherein the vinyl acetate-ethylene and/or styrene-(meth)acrylic ester copolymers are in the form of water-redispersible powders for producing hydraulically-setting building material dry formulations. Where the storage stability of the protective-colloid-stabilized vinyl acetate-ethylene or styrene-(meth)acrylic ester copolymers in the form of water-redispersible powders is improved by drying aqueous dispersions comprising protective-colloid-stabilized vinyl acetate-ethylene and/or styrene-(meth)acrylic ester copolymers, one or more water-soluble inorganic salts, and one or more desiccants. Where the water-soluble inorganic salts are selected from the group consisting of alkali metal sulfates and where the desiccants are selected from the group comprising polyvinyl alcohols, polyvinyl acetals, nonionic polyvinylpyrrolidones, nonionic poly(meth)acrylamides, polysaccharides and proteins.

摘要： A method of generating a wellbore treatment fluid comprising: obtaining a target Young's modulus; calculating a compressive strength requirement from a correlation comprising compressive strength and Young's modulus using the target Young's modulus as an input; classifying a plurality of solid particulates using correlations; calculating a reactive index and/or a water requirement for at least one of the solid particulates; and selecting two or more solid particulates from the plurality of solid particulates to create a wellbore treatment fluid, wherein two or more solid particulates are selected such that when the wellbore treatment fluid is prepared and set, the set wellbore treatment fluid has a 24 hour compressive strength greater than or equal to the compressive strength requirement.

摘要： A multi-component inorganic capsule anchoring system can be used for chemical fastening of anchors, bolts, screw anchors, screw bolts, and post-installed reinforcing bars in mineral substrates. The multi-component inorganic capsule anchoring system contains a curable powdery ground-granulated blast-furnace slag-based component A, and an initiator component B in aqueous-phase for initiating the curing process. The powdery ground-granulated blast-furnace slag-based component A contains further silica dust. The component B contains an alkali- or alkaline earth-hydroxide, alkali- or alkaline earth-carbonate, or alkali-or alkaline earth-sulfate component.

摘要： A method for preparing a graphene-nanosheets based concrete additive is disclosed. The method comprises mixing Polycarboxylate ether A (PCE-A) to a retarder - based salt solution to obtain a retarder-based Polycarboxylate ether A solution. In the next step, a retarder based PCE solution is obtained by adding Polycarboxylate ether B to the retarder based Polycarboxylate ether A solution to which graphene nanosheets are added. Further, an air entrainment agent is added to graphene nanosheets based PCE solution and further mixed to obtain the graphene nanosheets based concrete additive.

摘要： A precast concrete molded body is provided, which is a cured product of a concrete composition. The concrete composition comprises: a microcapsule; cement; and at least one type of aggregate. The microcapsule is provided with a core-shell structure having i) a core made of a water repellent organosilicon material selected from the group consisting of organosilanes, organosilane partial condensation products, and branched siloxane resins, and ii) a shell made of a silicon-based network polymer containing silica units. The concrete composition contains 0.01 to less than 0.5 parts by weight of microcapsules per 100 parts by weight of cement. Thereby, a precast concrete molded body can be provided, having high strength, as well as at least one of the following properties: air content stability, substance penetration prevention, and freeze-thaw resistance.

摘要： An additive injection system can be a part of a cementitious slurry mixing and dispensing assembly. The additive injection system can be used to inject an additive into an auxiliary slurry discharge conduit carrying a secondary flow of cementitious slurry produced in the assembly such that the secondary slurry stream is different from a main slurry stream discharged from a main slurry discharge conduit.

摘要： The present invention is directed to processes for making cementitious construction material, in particular magnesium oxychloride (MOC) cementitious construction material (e.g., MOC boards). The processes relate to one or more operations of the overall material production process, including material storage and handling, mixing of materials, curing to form magnesium oxychloride cement, board handling, and/or packaging. Various processes of the present invention involve process control strategies and/or algorithms to provide improved processes for producing construction material. In particular, the processes of the present invention provide improvements in board properties as detailed below (e.g., racking strength), speed of board production, economics of board production, reduction in complexity of manufacture, improvements in consistency of board manufacture, and improvements in quality control.

摘要： A method of sequestering gas-phase materials, hempcrete formed using the method, and methods of using hempcrete are disclosed. An exemplary method includes providing a mixture of hempcrete compound material within a chamber and exposing the mixture within the chamber to a gas for a period of time to form hempcrete, wherein the hempcrete exhibits net-negative life cycle carbon emissions. A model to predict net life cycle carbon emission of hempcrete is also disclosed.

摘要： Disclosed is a concrete product incorporating rubber aggregate produced by casting under pressure. The concrete product may optionally be cast at 6.9-27.7 MPa for periods of, for example, 24 hours. In one embodiment the rubber aggregate may comprise coarse and/or fine rubber aggregate to replace natural sources of coarse and fine aggregate. Casting under pressure was found to generally improve the performance characteristics of the concrete when compared to corresponding concrete cast without pressure.
