  • Publication number: 20240109808
    Abstract: Disclosed herein is a transportable bio-cement comprising a desiccated microorganism package; where the microorganism package comprises one or more microorganisms; a first binder, where the first binder is produced by the microorganism; and where the microorganism has protected itself by a layer of the first binder; where the transportable bio-cement is devoid of moisture. Disclosed herein too is a method of manufacturing a transportable dry composition comprising blending together a microorganism package; a nutrient; and a liquid; activating the microorganism package to produce a first binder; subjecting the microorganism package to desiccation to form a transportable bio-cement; and blending the transportable bio-cement with an aggregate to form a bio-concrete; where the aggregate comprises a substrate, a second binder, and a liquid.

  • Publication number: 20230139941
    Abstract: 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.

  • Publication number: 20220371953
    Abstract: Methods of forming cement pastes, methods of forming concrete, and methods of forming other compositions using mineral particles formed from the one or more of biomineralizing microorganisms and biomineralizing microorganisms. Desired features, such as size and morphology, can be controlled by controlling growth parameters of the biomineralizing microorganisms and biomineralizing microorganisms.

  • Publication number: 20220363597
    Abstract: Methods of forming synthetic aluminosilicate material are disclosed. Exemplary methods include forming a polymer solution, adding an aluminum precursor to the polymer solution, adding a silicon precursor to the polymer solution, forming a gel from the polymer solution, calcining the gel to form an aluminosilicate powder, and grinding the aluminosilicate powder to form ground aluminosilicate material. The synthetic aluminosilicate material can be used in the formation of cement and concrete.

  • Publication number: 20220340487
    Abstract: Acid-resistant composite materials and methods of forming acid resistant composite materials are disclosed. The acid resistant composite materials can include one or more monovalent, divalent, or polyvalent cationic metals. The acid resistant composite materials can be used, for example, in the formation of concreate or as a coating for concrete.

  • Publication number: 20220298075
    Abstract: Cement paste compositions, concrete compositions, and methods of forming the cement paste compositions and concrete compositions are disclosed. Exemplary cement paste compositions and concrete compositions include a water-soluble additive that is dissolved and is configured to perform one or more of ice recrystallization inhibition and dynamic ice shaping when the cement composition is exposed to temperatures less than or equal to a freezing temperature of water.

  • Patent number: 8759424
    Abstract: A composite material includes a matrix composed of a polyhydroxyalkanoate (PHA) polymer and a filler composed of particles dispersed in the matrix. The particles are composed of naturally-derived materials (e.g., ground bone meal or pumice powder), have a microporous microstructure, have a low hygroscopic expansion, and are less than 1.0 mm in size. Preferably, the matrix and the filler together constitute 100% by weight of the composite material, and at most 30% by volume of the composite material is consumed by the filler. The composite material may take the form of an anaerobically biodegradable article of manufacture such as a building material a coating of a building material or other article.
