Kalkgebundenen

Kalkgebundenen is a German adjective used to describe materials in which calcium carbonate (Kalk) serves as the binding phase. The term is derived from Kalk (lime) and gebunden (bound) and appears in technical contexts to indicate that lime or calcium carbonate forms the cement or matrix that holds together components such as grains, aggregates, or soil particles.

In geology and sedimentology, kalkgebundene Gesteine or Sedimente are rocks or sediments in which calcite precipitates bind grains, forming a cement. This calcite cement can reduce porosity and influence properties such as strength, permeability, and diagenetic history. Calcite cementation often develops during fluid-rock interactions and affects the texture and evolution of carbonate and clastic rocks.

In construction and historic masonry, kalkgebundene Mörtel or Putze denotes lime-based binders used to assemble and bind aggregates. Such mortars rely on lime (calcium hydroxide) that slowly re-carbonates to calcium carbonate, providing breathability and compatibility with historic materials. Hydraulic lime variants introduce pozzolanic materials to accelerate curing and improve early strength, illustrating the range of formulations described by the term.

In soil science, kalkgebundene Böden describe calcareous soils with significant carbonate content that acts as a binding agent among particles. This binding influences soil structure, stability, drainage, and pH, and can lead to features such as caliche formations in arid regions.

Overall, kalkgebundenen signals the presence of calcium carbonate as a binding component across disciplines, with implications for texture, durability, and chemical behavior depending on the material and context.
