Concrete Flu or "Efflorescence is a salt deposit on the surface of concrete. White deposits forms by the reaction of Ca(OH)2
with CO2, which is typical carbonation of concrete. Therefore, efflorescence technically provided by concrete permeability.
For instance, when water percolates through poorly compacted concrete; concrete with shrinkage cracks or highly porous
one; also along bad made joints, and evaporation take place from the surface of concrete. Especially harmful is concrete with
shrinkage and superficial porous system, which is straight indication of high slump at 4” concrete mix" .
KALMATRON® KF-A (USA Patent #5,728,208) as an admixture to the cementitious mixes is the most advanced modifier of
concrete rheology reorganizing macro-micro pores’ ratio wherein amount of micro pores is about 97% and macro pores at 3%.
domination of capillaries and micro pores which prevents hydraulic thresholds. This is the one of the reason of concrete with
KF-A impermeability and gained compressive strength preventing concrete from corrosion.
Another reason is reactivity of Calcium Hydroxide with KF-A as conceptual agents of ion exchange reactions. Some extracts
of equations shows, that the higher free-lime content the more productive structure forming process is:
2NaNO3 + Ca(OH)2 ↔ Ca(NO3)2 +2NaOH; (1)
Ca (NO3)2 + Ca(OH)2 ↔ 2CaOHNO3 ; (2)
CaCl2 + Ca(OH)2 ↔ 2CaOHCl; (3)
However, there is no “food” for CO2 and the end for Concrete Flu with added KALMATRON®.

COMPARATIVE TESTS OF CONCRETE SAMPLES, ASTM C39, AASHTO-22
Long term comparative test provided on the facilities  in 2008. Three types of the concrete samples designed with Flyash (A), Flyash and KALMATRON® KF-A (B), and KALMATRON®
KF-A (C) were placed on the ground that naturally contaminated by high content of Alkalis in Nevada.
Samples were removed after 45 days for observation and testing where concrete containing Flyash (A) is severely deteriorated and lost its strength as shown below on (A).
On Pic. 1 and 2 shown snow like Alkalis residue and destroyed concrete protected by Fiberglass Fibers premix and isolating membrane.
Pic. 3 Concrete Footer corroded after 2 years being
exposed to natural Alkalis.

Vividly, increasing of concrete density by the pore's blocking fillers and gaining of concrete weight do not provide concrete
protection from corrosion. Isolating of concrete structures by membranes or coatings perform certain postponing of ion
penetration and accumulating them resulting in abrupt structural failure.
KALMATRON® KF-A provides stable protection of concrete structure from chemical type of corrosion known as Concrete Flu
according to its performance in aggressive Alkalis and gaining of compressive strength.
