Lime mortar or torching [1] [2] is a masonry mortar composed of lime and an aggregate such as sand, mixed with water. It is one of the oldest known types of mortar, used in ancient Rome and Greece , when it largely replaced the clay and gypsum mortars common to ancient Egyptian construction.
Lime used in building materials is broadly classified as "pure", "hydraulic", and "poor" lime; [11] can be natural or artificial; and may be further identified by its magnesium content such as dolomitic or magnesium lime. Uses include lime mortar, lime plaster, lime render, lime-ash floors, tabby concrete, whitewash, silicate mineral paint, and ...
The Maquoketa and Hurstville Railroad was organized in 1888 to ship the burned lime instead of hauling it by wagon. Garwin Mace Lime Kilns, Menomonee Falls, Wisconsin, NRHP-listed; Quasius Quarry, near the Sheboygan River in Rhine, Wisconsin, NRHP-listed as the Sheboygan Valley Land and Lime Company. Includes a limestone quarry and kilns for ...
This contrasts with calcium hydroxide, also called slaked lime or air lime that is used to make lime mortar, the other common type of lime mortar, which sets by carbonation (re-absorbing carbon dioxide (CO 2) from the air). Hydraulic lime provides a faster initial set and higher compressive strength than air lime, and hydraulic lime will set in ...

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone.

The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient. The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns.
