The present invention generally relates to cementitious material that is a precursor of a magnesium oxychloride cement (MOC) and comprises treated carbon fibers comprising a dispersing agent at least partially coating the carbon fibers and processes for the preparation thereof. The present invention is also related to cementitious material that is a precursor of a magnesium oxychloride cement (MOC) and comprises siliconate and processes for the preparation thereof. The present invention further relates to cementitious material (e.g., pourable, extrudable, moldable and formable cementitious material) and cementitious construction material (e.g., boards, structural laminates, etc.) formed from curing the cementitious material.

A conductive concrete electric thermal battery includes conductive concrete; and a plurality of electrodes disposed in the conductive concrete, each electrode of the plurality of electrodes is mechanically isolated from every other electrode of the plurality of electrodes and configured to connect electrically to a source of electrical energy. The conductive concrete includes a mixture of concrete and at least one conductive material.

An ultra-stable structural laminate with fire resistance and a lateral nail pull strength from 44 to 300 pounds of force and an insulation R value from 1 to 40, the ultra-stable structural laminate of a cementious material with a nano-molecular veneer and a foam component catalytically reacted into an expanded closed cell foam having a thickness from ⅛.sup.th inch to 8 inches, a density from 1.5 pounds/cubic foot to 3 pounds/cubic foot that self-adheres to the cementitious material forming an ultra-stable structural laminate with fire resistance and a lateral nail pull strength from 44 pounds to 300 pounds of force, an insulation R value from 1 to 40, a resistance to seismic impact for earthquakes over 3.1 on the Richter Scale, a break point from 7 lbs/inch to 100 lbs/inch; and a resistance to wind shear equivalent to a 15 mph downburst.

A method of producing a stabilized fiber, including performing a heat treatment on an acrylamide polymer fiber under an oxidizing atmosphere in a stabilization treatment temperature range of 200° C. to 500° C. while applying a tension of 0.07 mN/tex to 15 mN/tex.

A multi-component inorganic capsule anchoring system can be used for chemically fastening 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 a curing process. The powdery ground-granulated blast-furnace slag-based component A contains further silica dust. The component B contains an alkali-silicate component and optionally a plasticizer.

The present invention relates to additives and, more specifically, the use of biochar, in concrete and other cementitious materials to provide for building materials that have a lower carbon footprint than their traditional counterparts. Traditional methods for production of cement produce large amount of carbon dioxide (CO2). When coupled with the massive demand for cement building materials around the world, this means that the cement production has a significant impact on the amount of CO2 produced globally. By including biochar and other additives along with, or instead of some traditional components of cement, one may be able to provide for cementitious building materials that sequester carbon, rather than release it.
