Lime Putties (Virginia
Traditional lime putties from both high-calcium limestone and
oystershell. This putty is made by burning the stone or shell
in a traditional wood fired lime kiln (producing quicklime), freshly
slaking it (adding water to the quicklime) from the kiln, and
it is aged for periods of time up to 12 months. The aged putty
is then added to sand and blended in a roller mill mixer (to achieve
good compression). This mortar can be used straight away or if
kept air-tight, can be stored indefinitely. In fact, aging your
lime putty mortar (recommended 6 weeks, kept air tight) produces
a richer, more workable mix.
Lime Mortar (Virginia
High-calcium lime putty mixed with ASTM-graded sands to produce
lime-putty mortar. This mortar is supplied with a portion of natural
hydraulic lime to be added on-site. This mortar is the best of
both worlds. You get the plasticity and feel of lime putty mortar,
with the increased set of a natural hydraulic lime.
Lime Mortars (Virginia
Hot lime mortar is made by taking quicklime and adding it to
damp sand and letting the moisture from the sand slake the lime.
Hydrated Lime, (Liner Rolpanit
Incorporated North America)
Dispersed 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.
Dispersed 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.
To 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.
Shelter Coats (Liner Rolpanit
Incorporated North America)
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.
Depending 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).
