The Kalmatron® company in which NRD Industries represents was founded by Dr. Alex V. Rusinoff, who discovered the Kalmatron® concept in 1982. His theory explained how the properties of concrete could be improved by changing the gel-crystalline ratio in the cement structure.
Kalmatron® Corporation is a manufacturer of Concrete Class Upgrading Admixtures and protective coatings for concrete structures under trademarks of Kalmatron®, K100® and Krete100®.
Applications provide impermeability to the liquids, high strength and resistance to corrosion. Patents issued for conceptual products are registered in the United States of America. The trademarks Kalmatron®, K100®, and Krete100® are
registered in the USA and Internationally.
Specifications of the products are provided and published by the U.S.A.
KALMATRON® KF-A is the first of the generation of chemically active admixtures to the cement containing mixes that increases cementiiotus value and volume of cement grain. Therefore, the lower quality cement has the higher the effectiveness of KF-A. That is why the results of applications are varying but always exceeding targeted one.
It is proven that KF-A, mixed with concrete mixes for different applications with 5 to 10 Kg/m3 or 8.5 to 17 Lbs/cuyd, provides stable high cementitious effects on the different stages of the forming concrete structure.
CONCRETE MIX with KF-A needs 10% to 30% less water than the standard dosage required of the same concrete mix design. Nevertheless, workability is even better with lower slump. We will recommend reduction of water for every particular concrete mix or mortar mix upon request it could be determined on a job site in accordance with our instruction.
CONCRETE MIX with KF-A has no bleeding, 2 to 3 times less shrinkage and fits to mould without corrections with very low slump. Exothermic temperature is 25% to 50 % lower, which allows avoiding the curing stage for the most known applications.
CONCRETE STRUCTURE with KF-A has no visual defects such as opened pores, cracks, flakes, dusty excertions, and efflorescence.
KALMATRON® KF-A is the highly economical solution that provides transformation of conventional concrete mix to High Performance Concrete without increasing of targeted cost for industrial volume of application.
How It Works
KALMATRON® KF-A provides a four step chain reaction with cement grain:
- Initial dissolution of cement grain by hydration.
- Oxidation of metal-containing elements.
- Colloidation of free molecules of water.
- Stabilization of the gel of the cement rock.
These reactions allow to reduce dosage of water by 10% to 30% less than the standard recipes and with low slump to get excellent workability. Increase of concrete’s matrix compaction by reduction of natural micro-cracks and hypertrophied volume of cement gel provides features of concrete durability.
- Early strengthening at 3rd to 7th day.
- Higher compressive strength at 25% to 50%.
- Shrinkage is lower at 2 to 3 times. Just no cracks at all.
- Exothermic heat is lower at 25% to 50%.
- No flakes, cracks, efflorescence, opened pores, and slid areas.
- Liquid impermeability is 100% beginning from 50 mm or 2″ of concrete thick.
- Increasing of freeze-thaw resistance up to 35%.
- Yield of concrete batch is higher by 3% to 6%.
- Highest resistance to chemical and climate corrossions.
- Highest adhesion to the most known porous materials.
Structured Nano-Acrylic Polymers the same concept of applicability has been observed for Bitumens, Epoxy, Acrylic, Polymers, Nano, Silicones, Liquid glass, etc.
The main disadvantage with epoxy adhesives is that they are very rigid if left unmodified. This rigidity results in lower impact resistance and peel strength than required for some applications. One way of modifying epoxy adhesives systems to provide greater toughness is to blend or co-react the epoxy with a more flexible elastomer such as polyurethane.
This is a temporary solutions created by such as mono, poly, oily, epoxy, bitumen, etc. based coatings even with premix of Fluorocarbon Based Polymer. With changing of ambient temperature, humid and direction of hydraulic pressure they loosing bond with supposed to be protected structure, cracking and blistering.
The main reason there are not following to the main properties of concrete coatings as follows:
Requirements imposed upon any Protective Cover Compositions (PCC).
1. PCC should become property of concrete and cannot depend on its initial characteristics to provide barrier against corrosive media.
2. Functional PCC penetrability into the concrete to assure continuous adhesion and reconstruction of concrete matrix on damaged depth.
3. Uniformity of PCC distribution properties over the structure to be protected.
All of the requirements are provided by adding of KALMATRON®KF-A admixture into shotcrete batch. KALMATRON®KF-A at
or its liquid version
performs non shrinkage cracks and complete liquids impermeability without needs to apply isolating membrane. That shotcrete is impermeable even to crude oil
