The
Complete Strength Gain Material
Protec III Liquid Silica Fume
with Acrylic Membrane is the highest
performing curing compound, hardener, shrinkage controller and overall
strength gain material on the market today for new concrete
floors.
|
Protec III LSF with Acrylic Membrane works on two
different levels.
- The Acrylic Membrane retains the highest level of
moisture to cure the concrete properly according to ASTM C309.
- With the addition of an extra hydration product,
liquid silica fume, the micro density is increased which produces
higher strength concrete with the lowest level of shrinkage.
It is generally known in the industry due to the number of increasing
failures that
dry shake
hardeners are essentially incompatible with
modern mix designs. They still produce higher compressive
strengths and hardness but now with low water to cement ratios and fly
ash they generally do not chemically (and mechanically) combine
properly. Tensile strength is often lowered dramatically by using
dry-shake hardeners in modern mix designs. This is due to the
fact that dry shake hardeners have never increased micro density but
used hardness only to increase strength. De-laminations are a
result of almost total loss of tensile strength (peeling of concrete
floors).
Penetrating
sealers that react with the concrete such as
silicates,
siliconates, and the special formula products that are marketed
as
liquid hardeners have also been used for curing. Although these
products produce denser surfaces, they generally will produce much
greater dry shrinkage and plastic shrinkage cracking because of their
inability to effectively retain sufficient moisture when curing.
This results in decreased tensile strength and in some instances
carbonation, dusting and curling of the concrete. The decrease in
tensile strength of liquid hardeners (silicates etc.) is much like the
decrease in tensile strength loss due to dry shake hardeners.
Acrylic cure
and seals do retain moisture adequately, but they do not
have strength (either compression or tensile) enhancing properties.

Protec III with Acyrlic Membrane
Protec III LSF with Acrylic Membrane
increases strength, especially tensile with its Liquid Silica Fume
component. This component produces very high hydration densities
in the top wear layer of a concrete floor. Protec III LSF with
acrylic membrane when properly
applied (within 0 - 3 hours after the new concrete floor has set) can
help eliminate plastic shrinkage cracking, carbonation, and
dusting.
Protec III LSF with acrylic membrane is overall the
highest performing strength enhancing material for concrete
floors. In fact it can help eliminate the problems that are
often experienced in new concrete floors and produces greater chemical
resistance. Protec III LSF with acrylic
membrane works by retaining moisture to the highest level along with
adding an extra hydration product, liquid silica fume. This
allows for a more controlled cure of the concrete, increases the
micro density and produces higher strength concrete with the lowest
level of shrinkage.
