Abstract: Various examples are provided related to manufacturing portland cement with thermal plasma. In one example, a method includes providing a raw kiln feed to a plasma arc gasification kiln; and forming clinker by heating the raw kiln feed in the plasma arc gasification kiln. The raw kiln feed can be heated with a plasma plume supplied with argon gas to a temperature in a range from about 1800°C to about 3000°C. In another example, a system includes a kiln feed system and a plasma arc gasification kiln that receives raw kiln feed from the kiln feed system and heats the raw kiln feed with a plasma plume to form clinker. The system can include a clinker processing system configured to process the formed clinker to produce portland cement.

Abstract: Aspects of the present disclosure provide for cement, cement paste, cementitious paste, cementitious mortar, and concrete, methods of making cement, cement paste, cementitious paste, cementitious mortar, and concrete, structures incorporating the concrete, and the like, where the cement, cement paste, cementitious paste, cementitious mortar, and the concrete include elemental boron and/or one or more boron compounds (e.g., boron-doped cement, cement paste, cementitious paste, cementitious mortar, and concrete). The boron and/or a boron compound can be homogeneously distributed throughout the cement, cement paste, cementitious paste, cementitious mortar and/or concrete.

Abstract: The present disclosure provides for cementitious shielding compositions, methods of making the cementitious shielding composition, structures incorporating the concrete cementitious shielding composition, and the like, where the cementitious shielding composition includes elemental boron and/or a boron compound, for example as boron particles. The boron particles can be homogeneously distributed throughout the cementitious shielding composition and can have a largest least dimension of about 100 microns or less. The present disclosure, in some aspects, can reduce or eliminate problems associated with minerals found in concrete aggregates, because those materials are degraded over time by neutron radiation, which leads to disorganized lattice structures, manifested as damage by radiation-induced volumetric expansion (RIVE), and potentially further damage from alkali-silica reaction (ASR).
