  • Patent number: 11034617
    Abstract: The present invention relates to a novel cementitious product produced from steelworks slag additivation to obtain material having properties suitable for use in the partial or total clinker replacement for the production of different types of cement. The process, which is also object of this invention, aims to adapt the properties of steelworks slag, by means of thermochemical treatment, including and preferably, but not only, still in the liquid steelworks slag pot, taking advantage of the thermal input of steel processing, to form a greater amount of alite (essential compound to increase pozzolanicity), under controlled conditions. After additivation, preferably, but not exclusively, the additivated steelworks slag is subjected to quenching, comminution and concentration to stabilize the alite fraction, to release the present phases and to remove any excess contaminants, such as metallic iron.

  • Patent number: 10260155
    Abstract: The present invention relates to a process for the preparation of Calcium Silicate Hydrate anion exchange membrane (cement paste) with an ionic conductivity of the order of 10?3 S/cm. The membrane can be formulated by mixing Ordinary Portland Cement (OPC) and water with the cement to water ratio of 1:0.45. After initial setting time, the membrane undergoes curing in 7% calcium chloride solution and the Cl? ions in the membrane is converted to OH? form by immersing into saturated Ca(OH)2 solution with pH 14 and it has been washed to remove the excess alkali. This membrane has high mechanical strength (Ultimate Tensile Strength: 6.3 MPa) and does not deteriorate even at high temperature (up to 450° C.) and alkaline atmosphere (pH 11.5-14). Also disclosed is a method of producing in-situ formation of membrane electrode assembly. This invention encompasses a process for producing and using the membrane in water electrolysis and fuel cell.

    Abstract: The present invention is directed to ready to use (wet) and setting (dry) repair products with antistatic additives having reduced persistent airborne dust particulates upon sanding thereof. Such wet and dry repair products include, in part, an antistatic additive(s) that can reduce or eliminate the static charge that forms in dust particulates when dried repair products, such as spackling compounds, cementitious materials, and joint compounds, are sanded, for example. In turn, this can help reduce the quantity of airborne dust particulates, the time in which they are suspended, and the distance they travel in a given room or job site. In one example, a repair product for use as a dry repair compound can include an anti-static additive, which can include a cationic charge, and optionally a metal complex. In another example, the repair product further includes water to define a wet or ready to use repair product.

  • Patent number: 8821633
    Abstract: A low-water-content castable composition produces cast products with an increased modulus of rupture, an increased cold crushing strength, and decreased porosity. The composition employs closed fractions of constituent particles with specified populations and specified gaps in the particle size distribution to produce these properties. The composition is suitable for refractory applications.

  • Publication number: 20140224154
    Abstract: Cement-SCM blends employ particle packing principles to increase particle packing density and reduce interstitial spacing between the cement and SCM particles. Particle packing reduces the amount of water required to obtain a cement paste having a desired flow, lowers the water-cementitious material ratio (w/cm), and increases early and long-term strengths. This may be accomplished by providing a hydraulic cement fraction having a narrow PSD and at least one SCM fraction having a mean particle size that differs from the mean particle size of the narrow PSD cement by a multiple of 3.0 or more to yield a cement-SCM blend having a particle packing density of at least 57.0%.

  • Publication number: 20140216302
    Abstract: An atmospheric storage mechanical weigh batch blend plant is shown with atmospheric storage for providing a dry, pre-blend, oilfield cement ready for mixing at the wellhead for slurry injection into a well head upon adding the proper amount of water and other fluids. The batch blend plant has three separate weighing mechanisms for (a) larger or bulk quantity materials, (b) intermediate quantities of materials, and (c) small amounts of additives to be included to the mixture. The entire weigh batch blend plant can be disassembled and moved. A special pressurized air bearing is used in the blender.

  • Publication number: 20140196901
    Abstract: A cement composition comprises: cement; water; and an additive, wherein the additive is a pozzolan and a strength-retrogression inhibitor, and wherein a mixture consisting essentially of: the additive; water; and a source of calcium develops a compressive strength of at least 500 psi at a time of 24 hours, a temperature of 190° F., and a pressure of 3,000 psi. A method of cementing in a subterranean formation comprises: introducing the cement composition into the subterranean formation and allowing the cement composition to set. The compressive strength of the test cement composition consisting essentially of: the cement; the water; and the additive at a final time of 72 hours has a percent change greater than ?5% from the compressive strength of the test cement composition at an initial time of 24 hours when tested at a temperature of 300° F. and a pressure of 3,000 psi.

  • Patent number: 8771748
    Abstract: Methods are provided for producing compositions, e.g. pastes or clays, which rapidly set into high-strength calcium phosphate products. In the subject methods, dry reactants that include calcium and phosphate sources, as well as a monovalent cation dihydrogen phosphate salt, are combined with a setting fluid and the combined reactants are mixed to produce the settable composition. A feature of the invention is that cements rapidly set into high strength product compositions. Also provided are the compositions themselves as well as kits for preparing the same. The subject methods and compositions produced thereby find use in a variety of applications, including hard tissue repair applications.
