Lime plaster is a type of plaster composed of sand, water, and lime, usually non-hydraulic hydrated lime (also known as slaked lime, high calcium lime or air lime). Ancient lime plaster often contained horse hair for reinforcement and pozzolan additives to reduce the working time.
Cement render or cement plaster is the application of a mortar mix of sand and cement, (optionally lime) and water to brick, concrete, stone, or mud brick. It is often textured, colored, or painted after application. It is generally used on exterior walls but can be used to feature an interior wall. [1]
A plaster relief picture made from shikkui. Shikkui (漆喰) is an ecological nontoxic Japanese lime plaster primarily made out of hydrated lime and calcium carbonate coming from reprocessed eggshells. It is mainly used for surface coatings of walls and ceilings in housing construction.
Hydraulic lime is a useful building material for the following reasons: It has a low elastic modulus. There is no need for expansion (movement) joints. It allows buildings to "breathe", and does not trap moisture in the walls. It has a lower firing temperature than Portland cement, and thus manufactured consuming less energy.
Uses include lime mortar, lime plaster, lime render, lime-ash floors, tabby concrete, whitewash, silicate mineral paint, and limestone blocks which may be of many types. The qualities of the many types of processed lime affect how they are used.
In limecrete, lime concrete or roman concrete the cement is replaced by lime. [16] One successful formula was developed in the mid-1800s by Dr. John E. Park . [ 17 ] Lime has been used since Roman times either as mass foundation concretes or as lightweight concretes using a variety of aggregates combined with a wide range of pozzolans (fired ...
Roughcast or pebbledash is a durable coarse plaster surface used on outside walls that consists of lime and sometimes cement mixed with sand, small gravel and often pebbles or shells. [1] The materials are mixed into a slurry and are then thrown at the working surface with a trowel or scoop.
Lime render is the first coat of lime "plaster or the like" [1] applied to the external surfaces of traditionally-built stone or brick buildings. It allows the building to 'breathe' – as lime is porous, it allows for the collection and evaporation of moisture .
