Technology
Hardeners are
silicate-based penetrating sealers.
They react with soluble
calcium compounds (free lime) in the concrete and form insoluble calcium
silicates to create a breathable protective barrier
The
new lithium silicates technology:
4Of the three
kinds of silicates, lithium silicates are very
reactive and are more
efficient than sodium or potassium silicates.
4Lithium’s reaction in concrete is
non-expansive, so it won’t
contribute to crazing or map cracking.
4Lithium reacts more
evenly throughout the
surface zone
4Lithium ions
are smaller than sodium and potassium ions, so they can
penetrate
concrete better.
Physically
: They increase the strength of the surface concrete and
fill the micropores to densify and decrease porosity.
Chemically :
The free lime CaO in excess
can react with water to form calcium hydroxide (CH = portlandite)
The silicates
(S) react with the CH to produce calcium silicate hydrate (CSH), the same material that results
from the reaction between portland cement and water, giving concrete much
of its strength.
Additional CSH means denser
and harder concrete.
Lithium silicates vs the old silicates technologies:
Older sodium and
potassium silicates form an expansive alkali-silica gel to seal the
surface.
This is why even properly finished and cured concrete can develop map
cracking after the application of sodium and potassium
products.
Sodium and potassium ions tend to react more
violently and unevenly, leaving clumps of reacted and unreacted calcium
scattered throughout the surface zone.
Benefits
back to home page
General
4The treatment is penetrating
and is a permanent protection.
4Surface sheen and protection
visible after 1 day - improves over 7 days of normal traffic and
maintenance.
4May be applied to new or
existing cured concrete.
4Polished areas can be put into service immediately after the process is
complete
Resistance
4Improved strength for old, deteriorating and weak concrete finishes,
providing increased resistance to abrasion and impact.
4Transformation of porous concrete into a dense surface that inhibits
water, oil and other contaminants from penetrating.
4Provides maximum hardening
to improve abrasion resistance and reduce dusting.
Chemistry
4Protects treated surfaces
from damage caused by water or chemical attack.
4Will not peel or flake off.
4Does not contain high
concentrations of sodium or potassium salts which can contribute to
surface crazing/surface ASR.
4Non-expansive gel will not
absorb water or cause floor to sweat.
4High lithium content to
combat surface ASR.
Maintenance
4Treated surfaces are easy to
maintain and require no waxing.
4Elimination of dusting from efflorescence (a white crystalline deposit
appearing on the surface of concrete that is caused by soluble salts
being carried upwards by moisture to the surface).
4Decreased floor maintenance and less wear on cleaning equipment such as
brushes, pads and mops.
