Dispersed Hydrated Lime

Product
Dispersed Hydrated Lime
SPECIFICATIONDispersed hydrated lime is a purely carbonating hardening binding agent for mortar, supplementary stone compound, grouting compounds, injection compounds and for plaster solidification. It is offered in the form of an aqueous suspension similar to pit lime.
COMPOSITIONDispersed hydrated lime is composed of hydrated whitle lime and mixing water. The proportion of solid matter is 50%.
The hydrated white lime has a (calculated) calcium hydroxide content of 96.1% weight. Dispersing aids are contained in the mixing water that do not exceed 2% weight.
MANUFACTURETo produce dispersed hydrated lime, dry hydrated white lime fresh from the factory with defined shearing performance is dispersed into the mixing water in a set time frame.
WORKINGDispersed hydrated lime is used in a similar fashion as conventional pit lime. To produce mortars or supplementary stone compounds, the dispersed hydrated lime is diluted and the filling materials are mixed in afterwards. Its workability is adjusted afterwards by adding a slight amount of water.
What is characteristic for mortars with dispersed hydrated lime is excellent resiliency and plasticity.
PROPERTIESThe lime compounds based upon dispersed hydrated lime carbonate significantly more quickly and completely than conventional lime compounds because the surface of the hydrated lime is increased by dispersion.
This also becomes apparent in higher mechanical values as well as in excellent resistance towards freeze=thawing cycles or salt blasting tests.

At the same time, the dispersed hydrated lime compounds are capable of completely reacting even in the thinnest layers. This makes it possible to use lime based compounds in the areas that were previously reserved for artificial resin-bound or artificial resin-modified systems. That means that free-flowing injection mortars and lime sludges may be applied in the thinnest cavities or the thinnest layers without obstructing their effectiveness. Dispersed hydrated lime has also proved its usefulness with plaster, supplementary and putty compounds since it is not inclined to "burn" and requires significantly less subsequent treatment (rewetting). Therefore, puttying may run to 0" without burning in the edge zones.

Mortars based on dispersed hydrated lime have the characteristics of early reacting and a high degree of early strength.

The high degree of effectiveness of dispersed hydrated lime makes it possible to significantly lower the binding agent requirements. For instance, only one third of the binding agent is required in comparison to conventional lime mortars.

Injection Compounds
SPECIFICATIONInjection compounds based upon dispersed hydrated lime are ready to use free-flowing suspensions made of dispersed hydrated lime and filler. They are stable in sedimentation and form a homogeneous zone bridging over capillaries in cavities.

They are suitable both for use in stone preservation as well as in the preservation of wall paintings and plaster. Furthermore, they are characterized by excellent workability, a low degree of shrinkage and a high degree of adhesive capacity.

They only bind as carbonate, meaning they do not contain any additional binding agents.

At the same time, the range of its physical and mechanical properties is so great that the injection compounds may be individually adapted to each building and each requirement.

COMPOSITIONThe injection compounds are composed of dispersed hydrated lime, marble powders or quartz powders, mixing water and dispersing aids(< 0.4% weight).

Depending upon the width of the cavity, the fillers may be adapted and the injection compounds may be either used undiluted with water up to 5% by weight.

It is not necessary to subsequently wet the areas injected.

Lime Shelter Coats
SPECIFICATION Lime shelter coats based upon dispersed hydrated lime are ready to use brushable and sprayable suspensions made of dispersed hydrated lime and fillers.
They are stable in sedimentation and form a homogeneous coating with capillary action.
They are suited for use in stone preservation as well as in the preservation of wall paintings and plaster. Furthermore, they are characterized by excellent workability, a low degree of shrinkage and high degree of adhesive capacity.
They only bind as carbonate, meaning they do not contain any additional binding agents. At the same time, the range of their physical and mechanical properties is so great that the lime shelter coats may be individually adapted to every building and each requirement.
COMPOSITIONDepending upon requirements, the lime shelter coats are composed of dispersed hydrated lime, marble powders or quartz sands and rock flour, mixing water and dispersing aids (< 0.4% weight).

WORKING For grouting, the lime shelter coats are applied with a brush or by spraying after prewetting with demineralized water.

The fillers may be adapted depending upon the thickness of application. It is also possible to have multiple layer grouting application.

The grouted areas should be subsequently wetted several times a day over at least 10 days.
