Abstract: Methods and systems for storing and mineralizing carbon dioxide in soil are disclosed herein. In some embodiments, the method comprises adding lime and carbon dioxide to a soil column including soil to form treated soil. After adding the lime and carbon dioxide, the method also includes strengthening the treated soil in the soil column by mineralizing the lime and carbon dioxide in the soil column. The method can further include adding a binder to the soil column and mixing the binder with the soil, lime, and carbon dioxide. The binder can include, for example, pozzolan, cement, cementitious material, and/or a manufactured calcium carbonate product.

Abstract: Provided are an energy-saving and environment-friendly non-autoclaved pipe pile concrete material with high impact resistance, and a preparation method thereof. Raw materials of the concrete include cementing material, sand and gravels, modified rubber fiber, water reducer and water. The rubber fiber comes from waste tires. The cementing material includes cement, slag powder and silicon powder. A content of the cementing material in the concrete is 400-500 kg/m3. A water-cement ratio is 0.19-0.22. A specific surface area of the slag powder is 400-450 m2/kg. A content ratio of the slag power to the whole cementing material by mass is 25-40%. A specific surface area of the silicon powder is 15-30 m2/kg. A content ratio of the silicon power to the whole cementing material by mass is 5-10%. The modified rubber fiber is obtained by making the rubber fiber undergo shallow carbonization and soaking the obtained rubber fiber with a modifier.

Abstract: There is provided a two part hardenable composition comprising a powder first part and a liquid second part. The parts are operable to form a glass ionomer cement which hardens to a solid mass upon mixing of the parts together. The composition comprises an inorganic glass and/or salt in the powder first part, an aqueous carrier in the liquid second part and an acid-functional polymer in the powder first part and/or the liquid second part. The composition also comprises an at least partially water-miscible additive in the first and/or second parts. The additive is operable to extend the working time of the glass ionomer cement upon mixing of the first and or second parts. The composition is operable to form a glass ionomer cement which, once hardened to a solid mass, has a plane strain fracture toughness of at least 0.7 MPa·m1/2 as measured at 24 hours from mixing. Also provided is a method of producing a glass ionomer cement.

Abstract: A method of manufacturing an activated pozzolan composition includes: (i) grinding a natural pozzolan, alone or with another mineral component that is not cement clinker, to form a finely ground pozzolan component having a first d90 in a range of about 10 μm to about 45 μm and a first d10 less than about 5 μm; and (ii) blending, without intergrinding, the finely ground pozzolan component with a coarse particulate mineral component comprised of coarse mineral particles not interground with the fine interground particulate component, the coarse particulate component having a second d90 greater than the first d90 and a second d10 greater than the first d10. The natural pozzolan can be one or more of natural pozzolanic deposits, volcanic ash, metakaolin, shale dust, calcined clay, trass, and pumice.

Abstract: Methods of the present disclosure relate to tailoring cement compositions to withstand carbon dioxide injection. A method comprises predicting a depth of carbonation in a cement sheath; predicting spatially varying mechanical properties of the cement composition due to the carbonation; and determining a mechanical response of the cement sheath based on the spatially varying mechanical properties of the cement composition.
