Definitions
- the invention relates to a method for producing a mortar corresponding to a historical mortar and lime sparrows and their use according to claims 1, 19 and 25.
- burnt lime which is taken from a lime kiln in pieces as quick lime, is placed in a fire-fighting trough and is quenched by adding water.
- the heat-releasing process of lime quenching is associated with the disintegration of the quicklime pieces until they are pulverized.
- Excess water that is extinguished immediately slurries the powder formed into lime sludge or lime milk. This is placed in a lime pit.
- the lime sludge which turns into a tough chalk dough, sediments and stores under the exclusion of water.
- the lime dough is called swamp lime. It was and is sought after for the historical production of mortar and the surface design of listed buildings.
- the present invention is therefore based on the object of reproducing historical mortar as precisely as possible in terms of composition and visual appearance using modern means in a relatively simple and inexpensive manner.
- the composition of a residual stock of this mortar is determined to replicate the historical mortar.
- the size of the lime sparrows contained in the historical mortar is also determined from the remaining stock.
- the lime sparrows are then produced separately and before further mixing with other components of the mortar, by producing the lime sparrows with a predetermined size as a relatively solid mixture of calcium hydroxide and / or calcium carbonate or another calcium compound and / or a mortar-compatible substance. After the lime sparrows have been produced, they are then mixed with the other components of the historical mortar determined in a mortar mixing system.
- the lime sparrows are usually made with a predetermined size that is larger than the size of the lime sparrows in historical mortar. The reason for this is that when the lime sparrows are mixed with the other components of the mortar in a corresponding mortar mixing system, there are at least minor crushing effects and the lime sparrows added are reduced to the lime sparrow size in the historical mortar. 4
- the lime sparrows are produced in a size of up to 10 mm and preferably 0.4 mm to 3 mm.
- Lime sparrows of corresponding size can be produced in one embodiment of the invention in that quicklime pieces are sprayed with water at least once and the moistened quicklime pieces are stored until they are completely extinguished.
- This type of production enables lime sparrows to be produced separately from the mortar mixing process more stably than when the burnt lime pieces were historically extinguished in damp sand.
- the lime sparrows produced separately in this way contain no lime residues.
- a strength-increasing substance can be added, preferably sprayed on, during storage of the moistened quicklime pieces.
- silicas can be used as such a strength-increasing substance, silicas in the form of water glass being preferred.
- Such a gas can be under pressure and / or be enriched with carbon dioxide, air being usable as the gas. It is also considered to be advantageous if the carbon dioxide has a higher partial vapor pressure than in the ambient air.
- gas or air enriched with carbon dioxide can accelerate the production of lime sparrows.
- the air can be enriched with carbon dioxide, for example, with at least partial use of a combustion gas.
- the supply of moisture to the quick lime pieces can also take place by covering them with a thin, moist layer of sand during storage. This 5
- a porous material granulate is used as the starting material instead of the quick lime pieces.
- This porous material granulate is mixed with a lime binder in order to obtain an alkalinity corresponding to the lime sparrows.
- the pores fill with the lime binder.
- calcium hydroxide, calcium carbonate or other calcium compounds can be used as lime binders.
- the porous material granulate can preferably be made from aerated concrete.
- the granulate can be introduced in a slightly pre-moistened manner and / or strengthening substances can be added to the granulate.
- the setting substances can, for example, be added to the spray water moistening the granules.
- the lime binding to the material granules can be carried out in modern mixing units and that the other components for forming the mortar can be added to these immediately after the lime sparrows have been produced.
- the porous granulate is first mixed with lime binder, whereupon the lime sparrows form. The remaining components of the historical mortar are added to the lime sparrows formed in the further mixing process.
- lime sparrows made from quicklime lumps it proves to be an advantage if they are added to a premix of all the other components of the historical mortar and then the lime sparrows are distributed in the premix by brief mixing.
- the lime sparrows are produced separately from the other mortar composition, so that they can also be handled as individual components in different sizes, as pre-made and optionally packaged aggregates and as individual products.
- prefabricated lime sparrows with a selected composition and size, depending on requirements can only be used as a component that can be mixed with the mortar when the mortar is produced and, if necessary, on the spot of the historic building.
- the composition of a plaster was analyzed at a strictly and a mortar with lime sparrows was prepared for the analysis.
- the analysis of the remaining mortar composition resulted in the following mortar composition:
- the limestone sparrows were obtained from 16 days of quicklime pieces stored in air, which were sprayed four times at three-day intervals, each with about 8% by mass of water, based on the mass of the quicklime pieces.
- pre-moistened aerated concrete granulate was added to the compulsory mixer. Lime was then added to the granulate and both components were first mixed to form lime sparrows. Then the remaining components were added, the mortar was mixed and bagged.
- the composition of the mortar may not be determined. Otherwise, the mortar is produced by the method according to the invention.
- the material imitating the lime sparrows in historical mortar can also be quicklime, for example.
