A carbonatable-based cementitious material may include one or more admixtures.
C04B 28/02 - Compositions of mortars, concrete or artificial stone, containing inorganic binders or the reaction product of an inorganic and an organic binder, e.g. polycarboxylate cements containing hydraulic cements other than calcium sulfates
The present disclosure describes compositions for cementitious materials and methods for making the same. The cementitious materials may be chemically activated concrete materials that utilize industrial byproducts and/or natural material, which may offer an environmentally friendly alternative to Portland cement and other traditional cement materials, lire cementitious materials may replace Portland, cement or be added to Portland cement to form construction materials.
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.

Synthesis of cementless fly ash based binders and applications thereof
Novel binder compositions have been discovered that offer an alternative to Portland Cement and reduced carbon dioxide footprint. The compositions typically include the reaction product of a mixture of fly ash, calcium oxide, nanosilica, water, and an effective amount of an activator. The 7, 14, and/or 28 day compressive strength may be at least about 15 MPa or more in some embodiments.

Hexagonal Boron Nitride (hBN) is a synthetic material that may be used in several applications due to its chemical inertness, thermal stability, and other beneficial properties. hBN composite materials and method for making such composites are described here. In particular composite materials including both functionalized hBN and cement or cementitious materials and methods for making the same are discussed. Such materials may be useful for construction, well cementing (both primary and remedial cementing), nuclear industry, 3D printing of advanced multifunctional composites, and refractory materials.

Mesoporous membranes have shown promising separation performance with a potential to lower the energy consumption, leading to a dramatic cost reduction. Recently, an extensive effort has been made on the design of membranes which brought a significant progress toward the synthesis of well-defined porous morphologies, most of which synthesized by surfactant-template methodology. Currently, the most well-designed state-of-the-art membranes using this technique are made from metals, polymers, carbon, silica, etc. In the present invention, we demonstrate mesoporous calcium-silicate particles having superior separation capacity and optimal permeability, thereby leading to reduced energy consumption for selective separation of gases/liquids and/or the combination thereof. We explore various methods to improve the calcium-silicate membranes properties by tuning pore density during the synthesis/aging process, while favoring the formation of uniformly distributed nanopores. Lowering particle density by controlling calcium to silicon ratio along with optimizing the surface area are essential in achieving our objective.

CALCIUM-SILICATE-BASED POROUS PARTICLES, COMPOSITION, METHOD OF MAKING AND USE THEREOF
A method for synthesizing calcium-silicate-based porous particles (CSPPs) is described. Control over CSPP morphology and pore size is achieved through a refined solution-based synthesis, allowing loading of a variety of sealants. These particles, upon external stimuli, release the loaded sealant into the surrounding material. Methods of loading the CSPPs with loading sealant are described. The CSPPs may be used in pure form or mixed with another material to deliver self-healing, sealing and multi-functional properties to a physical structure. The composition of the CSPPs is described, along with methods of use of the CSPPs.
