KALCRET hard compound is the general term
for cement bonded wear protection materials. These are
based on inorganic materials of high strength and good
wear resistance.
The specific density is attained by a
well balanced particle size distribution of the individual
components. The pores between the cement portions are
filled by the addition of superfine particles of micro
silica.
KALCRET reaches high compressive strength
after 8 hours. It is excellently suited for repairs.
The mixture includes defined additives and is made up
of:
- Hard aggregate materials
- Cement binder
- Micro silica
A specific portion of steel fibers is
added to enhance the structural strength. The type of
steel fibers used depends on the thermal, chemical and
corrosive stress to which the wear protection will be
exposed. Expansion joints will be provided when KALCRET
is used at higher temperatures.
Concerning its chemical resistance KALCRET
is more stable than regular concrete. However, KALCRET
can not be used as acid protection.
Ideal for material combinations
KALCRET is also fit for combination
with other materials from the Abresist Corp. wear protection
program, such as with
Installation: by
trowelling, casting in molds, or spraying.
Application temperature:
up to 1200°C / 2192°F depending on material,
application and geometry.
Advantages: highly wear
resistant, strong and jointless lining,
highly temperature resistant.

KALCRET®-S Sprayable Hard
Compound
Sprayable
Abrasion Resistant Lining for
Large Surfaces, Installs Quickly, Even Overhead
|
|  New
spray system applies abrasion resistant
KALCRET®-S wear compound to large
surfaces quickly and reliably, in a uniform,
compact layer, free of joints. KALCRET®-S
significantly reduces wear and abrasion
on system components and pipes in many industries
including cement, power, glass, iron/steel,
mining, and refuse incineration.
KALCRET®-S hard
compound is a mixture of hard aggregate
materials ranging in size from 0-4 mm and
consisting of bauxite or corundum (depending
on application), cement binder and micro
silica. Defined amounts of steel fibers
add structural strength.
- Spray system delivers a
continuous, uniform layer.
- Spray horizontally or vertically
to achieve a joint free lining.
- Surface can be smoothed
immediately after spraying.
- No sandblasting required
before application.
- Fast application rate >
5m²/Hr. (54 sq. ft./Hr.)
- 24 hour setting time.
- Use at temperatures up
to 1200°C (2192°F).
- Excellent thermal shock
resistance and oxidation stability.
- Thicknesses range from
20 to 100mm (.78" to 3.93"),
depending
on severity of wear.
- Use wire mesh or anchors
for mechanical attachment.
