Description

C04B covers the manufacture, composition, and properties of inorganic binding materials and their derivatives, including lime, magnesia, and cementitious materials (Portland cement, slag cements, etc.), as well as their composite applications in mortars, concrete, and other building materials. The class encompasses artificial stone production, ceramic materials and manufacturing processes, and refractory compositions designed for high-temperature applications. Also included are methods and materials for treating, processing, or modifying natural stone products for construction or industrial use.

Scope Notes

Glossary: Active ingredients active ingredient Ingredients having an effect on the mortar-, concrete- or artificial stone composition during processing or on the characteristics of the final product, e.g. as set accelerator, as dispersant or as gas generating agent. Other examples are processing aids or property improvers, e.g. grinding aids, used after the cement burning process or in the absence of such a burning process. Cement cements The binder proper, i.e. excluding any additional ingredient or additive added to the finished binder as such, with the exception of mixtures of binders. Cement composition Cement compositions In patent literature this term might be used in the sense of " cement " as well as in the sense of a "mortar-, concrete- or artificial stone composition". For classification and search, the term must be interpreted using the Glossary as guidance. Clinker Clinkers The unground sintered product leaving the cement kiln. In patent literature this term might be used literally, i.e. to indicate the unground sintered product leaving the cement kiln, or it might be used to indicate the ground cement without any additive, i.e. not interground with additives such as gypsum. Ceramics Inorganic, non metallic products obtained by a process involving a shaping step and a sintering or comparable heat treatment step, with the exclusion of cements , cermets and glasses, glazes, vitreous enamels and devitrified glass ceramics . Fillers filler Inactive ingredients, include pigments, aggregates and fibrous reinforcing materials. Fine ceramics Ceramics having a polycrystalline fine-grained microstructure, e.g. of dimensions below 100 micrometer. Hydraulic binder Hydraulic binders For the purpose of classification and search in this subclass, the terms " cement " and " hydraulic binder " are considered to be equivalent, even if in literature, an hydraulic binder might be defined as a mixture of cement and one or more inorganic additives. Mortar-, concrete- and artificial stone compositions Mortar-, concrete- or artificial stone composition Compositions of mortars, concrete or artificial stone Mortars, concrete or artificial stone Mortars, concrete, artificial stone They are considered as a single group of materials, are mixtures of one or more binders with fillers or other ingredients. In the context of such compositions, the terms " cement " and "binder" are considered equivalent. Resin mortar or resin concrete Mortar or concrete containing resin as a binder instead of cement , i.e. excluding any inorganic binder and containing a considerable amount of inorganic filler compared with the amount of the organic binder. Refractories Ceramics or mortars withstanding high temperatures of at least about 1500 degrees C. For classification and search in this subclass no substantial distinction is made between the terms "refractories" and "ceramics". Porous materials porous material Materials which are deliberately made porous, e.g. by adding gas-forming, foaming, burnable or lightweight additives to the composition they are made of. | Limiting references: Granulating apparatus Mechanical features relating to the working of mortars, concrete, stone, clay-wares or ceramics, e.g. mixing or shaping ceramic compositions, boring natural stone Chemical preparation of powders of inorganic compounds Devitrified glass-ceramics Compositions containing free metal bonded to carbides, diamond, oxides, borides, nitrides, silicides, e.g. cermets, or other metal compounds, such as oxynitrides or sulfides, other than as macroscopic reinforcing agents Building elements or constructions; Finishing work on buildings
