 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" [1]. 

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%. 

Therefore, KF-A reduces volume of porous system of concrete structure by completed cement hydration resulting in 

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®.

[2] - Matthew Notto   Placement of the samples took place on Bishops Storehouse,   Virginia Ave, Overton, NV. Tested by "Landmark" Testing and Engineering Co.

Long term comparative test provided on the facilities [2] 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).


Sample is here
On Pic. 1 and 2 shown snow like Alkalis residue and destroyed concrete protected by Fiberglass Fibers premix and isolating membrane.

       exposed to natural Alkalis.

Pic. 4 Shown barely seen concrete sample placed on a  
      ground 45 days ago.     
Pic. 4 Isolating of the concrete footer from ground by isolating membrane and added Fiberglass Fiber did not perform protection from corrosion. Shown exposed Fiberglass Fiber from concrete.     
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.
