Abstract

NOVELTY - A hydraulic binder comprises a source of calcium aluminate, calcium silicate, sulfate, and a source of reactive silica. The ingredients are present in such relative proportions that, upon hydration, both monosulfate and hydrated alumina are formed. USE - The binder is used for forming non-efflorescing cementitious bodies, e.g. roofing tiles, plates, cladding, and walls (claimed). ADVANTAGE - The hydraulic binder reduces or eliminates efflorescence while maintaining the physical properties of cementitious bodies at satisfactory levels. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of forming a non-efflorescing cementitious body, comprising curing the hydraulic binder.

Binder (material)

A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion. In a more narrow sense, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it. Examples include glue, adhesive and thickening. Examples of mechanical binders are bond stones in masonry and tie beams in timber framing.

Concrete

Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that is easily poured and molded into shape.

Cement

A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource.
