Admixtures

KF-A

is the Swiss Army Knife of Concrete Admixtures.
it is a water reducer, plasticizer, water proofing and shrinkage controlling agent, curing compound, corrosion inhibitor, cement upgrading and high early strength admixture.
Safe for food and drinking water, NSF Reg. #136880, Category Codes: R2 and RX‐2.

We will be supplying pre mixed bags (22.7kg) very soon where the customer and contractor just adds 2.3 L water and mixes it. It will give over 50MPA, designed for structural repairs in any environment.

It will stick to any porous material including concrete metal & asphalt. The metal can be rusty and corroded. It will chemically bond and prevent any more deterioration restoring post tensional strength and be waterproof.

KF‐A acts by four ways after adding into the concrete batch:

  1. As a Water Reducer during of mixing and pumping time;
  2. As a Plasticizer during of transportation and placement time;
  3. As a Shrinkage controlling and Curing Compounds during of setting time;
  4. As a Strength gainer and Impermeability performing agents of hardening time.

KF‐A applicable by:

  • 8.5 LB/CY or 5Kg/m3 into conventional concrete mix;
  • 13 LB/CY or 7.5Kg/m3 into pre‐cast concrete mixes;
  • 17 LB/CY or 10Kg/m3 into the plaster and shotcrete mixes.

Agitation Of Cement Hydration

Actual hydration of cement occurs by superficial absorption of water on the depth of cement grain at 16% during one year. Unaccomplished cement hydration causes immaturity of concrete structure depending on purity of environment for decades. Therefore, the speed and depth of cement hydration are major factors of concrete durability.

 

  • “For a cement particle that measures 50 μm across, the depth of hydration is 4 μm at 28 days and 8 μm after a year. Full hydration has only been obtained by grinding cement in water continuously for five days. The standard average across measurement of a cement particle is over 90 μm.”
  • Diminishing size of hydrating cement particle has only be obtained by KALMATRON® KF‐A admixture providing decay‐hydration of the cement grain from 100 μm to 10 μm in a first 20 minutes. Completed hydration expected to be observed during of hardening hours when augmentable water is available.

 

This property propagated KALMATRON® KF‐A for advanced replacements of ISOLATIONS, FIBERS, SILICA FUME, MICROCEMENTS, etc. KF‐A is a cost‐effective solution that provides a transformation of conventional concrete mix to High Performance Concrete. For instance, concrete or mortar made with KF‐A has no shrinkage cracks, impermeable to the liquids and resistant to known types of corrosion.

Low slump and viscous workability are resulting in a properties of High Performance Concrete of conventional concrete mix with KALMATRON® admixtures.

Low cost per unite of applications brings new economy to the concrete technologies with twice longer terms of inter repair durability.

KALMATRON® KF-A or its liquid version K100®, as a cement hydration agitators, postpones* molecular bonding of Three Calcium Silicate, which allows accomplish cement hydration during of at 5 to 8 hours instead of 5-6 decades.

At left and at right shown the SEM’s photograph and concrete cylinder made of concrete based on High Alumina Cement and concrete cylinder made of conventional concrete mix with added KALMATRON® KF-A respectively. Both of concrete cylinders represents the samples of the groups tested in Dionized Water (H2SO4) in accordance with protocol of Redner Test.

Comparing both of SEM’s photographs, the Integral Surface (IS) of “A” is smaller than IS of “B” that presupposes faster speed corrosion of “A”.

Dual nature of High Alumina Cement to provide faster hydration alters kinematics of deformation in this particular type of composites resulting in tensional cracks after.

Mass loss of “A” is 6 times more than mass loss of “B”. Changing of coloration of “A” could be explained by belite decomposition in sulphuric acid.

Therefore, completed cement grain hydration by KALMATRON® KF-A admixture do not leave agential volume for any acidic reaction.

Attack Of Concrete - Sulphure & Microbial Corrosion

“Concrete sewer structures and pipes are corroded by sulphuric acid which destroys the cement binder and ultimately results in corrosion of the reinforcing steel. Sulphuric acid is produced in sewers by a complex chain of microbiological and gas/liquid solubility stages which occur as the sewage travels through the sewerage system.

 

These bacteria can create levels of sulfuric acid concentrations as high as 7%. This acid diffuses into the concrete structure, destroys the cement gel binder, and forming soft and soluble gypsum (calcium sulphate hydrate)” [1].

 

“KALMATRON® KF-A admixture to concrete mixes is a conceptually new product patented in the USA (#5,728,428). This is an inorganic oxidizer of micro/macro metal elements contained in cementitious materials providing electro-chemical decay of cement grain by electrolysis between inversely charged particles of electrolyte and cement grain.

 

KF-A falls under the classification of the following types of ASTM C 494:

  • Type C – cement hydration accelerator;
  • Type F – high range water-reducing admixture;
  • Type S – specific performance admixture.

Decay-hydration reactions result in maximum hydration/decay of cement grains and volume of cementitious paste as a continuous solid phase in which the aggregates are embedded.

 

Any ingredient of the concrete batch with certain sorption ability is vulnerable to any liquid/gas corrosion. The photograph at right shows corroded coarse aggregate when cementitious paste protected by KF-A was perfectly intact. Therefore, completed cement grain hydration by KF-A admixture do not leave agential volume for any acidic reaction.

cc_kfa_atk1
The attack of concrete cementitious part takes place mainly above the normal sewerage flow level. Sewage is rich in sulphur-containing materials, both organic (protein, etc) and inorganic (sulphates, etc).

Does Concrete Exist Under Ph Of 3?

Yes, It Does With Kalmatron®!

This test procedure is based on comparison of building materials submerged in a solution of 1.00pH, which is close to battery acid.

Conventional concrete with added 17 Lbs/yd3 of KALMATRON® KF-A was tested also and survived 62 cycles with 4% of mass loss [5]. Information about control and compared specimens was not available.

We believe that pH =1 level is not suitable for any cement containing material. As it follows from the source [6], concrete is testable in a range of acidity at 3pH to 6pH. The level of acidity over 6pH is a normal corrosive environment for concrete. Inversely, acidity below 3pH is corrosive on a level of cement grain and not testable for cementitious materials. But it does work for concrete with KALMATRON®.

cc_kfa_does1

cc_kfa_does2
Repair of concrete manhole from inside. Spraying of KALMATRON® provided stable renovation to the structural strength, impermeability, and corrosion resistance. Important economical issue is that the surface before application was not sand blasted and was not washed with acid solution.
cc_kfa_does3
This is an example of the control concrete specimen deterioration in 10% acidic solution [3].

Mass Increasing Type Of Corrosion

The mass increasing type of concrete corrosion occurs in the salt, alkali, ligno-sulphate, and sugar containing environments.

The mechanism is simple, fast, and dangerous by unpredictable terms of structure exhaustion.

 

The concentration of aggressive media rises into the concrete, and results in the production of crystals with genesis respectively to dissolved agent. Physical tensions of crystals in the concrete causes massive and quick micro-cracking with consequent crumbling of the structure. Rebar looses its binding with concrete in the first few months.

cc_kfa_chart4

Sugar 15% Solution; Weight Increase:
Kalmatron® KF-A = 2 Gr
Silica Fume = 7 Gr

The sugar-water solution is one of the fastest agents, because it is chemically active with cementitious elements. That’s why it was chosen for demonstration of KALMATRON® KF-A effectiveness, shown on the picture at right

 

Therefore, protecting the cement grains should be provided by completely hydrating of cement to assure binding of the concrete. KALMATRON® KF-A is designed to provide complete hydration of cement grain for concrete protection.

The most preferable way to repair damaged sewage concrete structures is by lining with a corrosion-proof repair coat containing KALMATRON® KF-A, seen as one of the few viable options for prolonging the service life of concrete sewer structures

KF-SEA

Admixture to salt-contaminated sand and gravel. Designed to be used with aggregates and salt water taken from the seashore. Highest resistance to corrosion and liquid impermeability.

cc_kfsea_intro

Can salt water be used for batching concrete?

The answer is NO.
Salt is damaging to concrete and causes it to break down over time. A common example of salt damage are spalled driveways in colder climates, where freeze-thaw cycles and de-icing salts work in tandem and cause the concrete to break or “flake”.

 

However, it is not only possible, but also practical and cost effective to use salt water and salt-contaminated sands and aggregates with the admixture KALMATRON® KF-SEA

 

KALMATRON® KF-SEA is an admixture to regular concrete mixes containing unwashed sea-sand and sea-gravel, where hydration of cement may be provided with sea-water as well. It is a non-organic, cementitious compound in powder form, of a light gray color.

How it works?

KF-Sea discharges the electrochemical potential of most sea-salts, which are aggressive to the concrete structure, negating the effect of the salts and rendering them harmless. In fact, these salts behave as electrolytes, resulting in increased solubility of clinker minerals and the complete hydration of cement.

 

“[Salts] also accelerate the exchange reactions. The resulting products of hydrolysis and hydration, which are in the form of crystals and gel, actively coagulate. It should be noted that gel expands due to the absorption of a large amount of water. This enhances adhesion of the aggregate of the mix and results in clogging of pores and compaction of the concrete stone.

 

“Therefore, the relay-like character of the reactions results in rapid formation of a primary framework of acicular crystals of calcium hydroxo-salts at the stage of concrete setting. This framework is overgrown with lamella crystals of calcium sulfoaluminate, calcium nitrochloroaluminate and calcium hydrosilicate. The formation of hardly-soluble crystalline structures raises the density of the cement stone and acts like a micro-reinforcement. These structures reduce permeability of concrete and preserve its compressive properties.” [“Chlorides in Concrete” by Dr. Alex V. Rusinoff, 2012]

Performance

KF-SEA concrete performs best in the same environment from which the raw batch materials were taken. KF-Sea is dosed by 12 kg/m3, 14kg/m3, or 16/m3. The average or standard dose is usually 13 kg/m3. Trial batching with local raw materials is the best way to determine the optimal dosing for every individual project location.

Apperance

The appearance of concrete and mortar structures produced with the admixture KF-SEA is different from the look of any regular concrete. The upgraded concrete is very dense, at 2,400 Kg/m3 to 2,700 Kg/m3, and black or very dark gray in color, with density close to that of natural rock. The dark color of the concrete structure is an indication of complete mineralogical oxidation, or so-called “ironing of concrete”.

Uses

KF-Sea is used for enhancing concrete and reinforced concrete in centrally loaded foundations, pillars, walls, columns, etc. except for bending elements with a thickness less than 450 mm / 17.7 in.

Fields of application include: industrial and military hazardous waste facilities, dams, piers, marinas, tunnels, heavy traffic roads, ramps, seaports and airports.

Economical Advantages

  • Absolute independence from suppliers of sand, gravel, and water. Take them from the sea-shore.
  • No other chemicals should be applied with KF-SEA.
  • Cost of ready mix concrete with KF-SEA is 40% lower than with salt resistant HP concrete; 25% lower than with conventional concrete

Benefits For Concrete Structure

  • KF-Sea is designed to be used with natural and unwashed sea-fillers, with higher durability than any known HP concrete mixes:
  • Provides absolute resistance to salt corrosion of concrete structure, also preventing metal anchor and rebar rusting.
  • Highest liquid impermeability and resistance to vapor transmission
  • Reduces exothermic heat up to two times.
  • Highly resistant to chemical corrosions and freeze-thaw cycles.
  • Stable resistance to core efflorescence.
  • Mortars with KF-SEA are very adhesive to concrete and granite.

Benefits For Concrete Application

  • Water reducer: workable with water-cement ratio reduction of 10 to 20%.
  • Increases compressive strength by more than 35%.
  • Increases density, reduces shrinkage & accelerates early strength.
  • Increases yield of the ready mix concrete by 8%.
