In the whole range of our products we put emphasis on their system compatibility, i.e. the capability of mutual combination creating a perfect complex where each component is harmonised within the whole. As Fornivel system is concerned, Fortecoat 1410 primer coat helps the dry component prepare the underlayer prior to the dry component application. Fortecoat 1420 and 1421 ensure further surface treatment and hardening. In Fortedur system, Fortecoat 1425 and 1426 ensures that sufficient time is allowed for a filled floor hardening by preventing water loss, reducing matured floor absorption significantly. In FormulaForte system, FormulaForte Hard is used for hardening and FormulaForte Shine for higher gloss. Combining our products, you can achieve improved floor performance properties.
Special additive ASA chemically modifies the course of hydration reaction and compensates for the concrete mixture shrinkage during setting and hardening. Using this additive, increased volume stability = lower tendency to crack generation is ensured. When used in floor materials (filling, self-levelling screed), the generation of cracks is reduced, as far as material is concerned. When used in filling materials (mortar, grouts), it also ensures filling and fixation of the areas concerned. In the long-term perspective, i.e. in the first few months - the use of the additive improves the shrinkage curve.
By combining several types of cement, fineness of grinding and¨special additives, one can achieve chemical retention of most of the mixing water in the hydratation product crystal lattice. This effect reduces shrinkage of the set cement due to drying and the generation of shrinkage cracks in the material. Rapid initiation and progress of chemical reactions shortens the time before the material foot traffic, with the presence of water in the crystal lattice also providing for fast decrease in the cement mass internal humidity, which enables laying after only a relatively short technological break.
SILICA EFFECT is achieved by the use of very fine spherical particles with high content of amorphous silicon dioxide filling in the area of set concrete, while reacting with calcium hydroxide and thus improving the quality of the contact zone between aggregates and cement. This results in decreased porosity and consequently a decreased seepage, increased freeze resistance, and corrosion resistance, higher strength (compression, bending tension, abrasion) and an improved compactness.
Most of our competitors use standard silicates containing sodium, potassium and/or lithium atoms in their manufacture. Parallel chemical reactions occur along with hardening producing undesirable salts with the atoms mentioned above. This is accompanied by lower treatment efficiency, defective structure and aesthetic defects in the form of surface whitening after the washout of the salts from the construction material. Pure silicates, on the other hand, do not generate these salts which results in significantly better surface treatment, eliminates the risk of defects and surface whitening.
The process of chemical hardening is based on two interrelated processes- 1) the transformation of the active component liquid phase to rigid silica C-S-H gel in the pores of the material accelerated by an organometallic catalyst and 2) the transformation of particles with low hardness to particles with significantly higher hardness.
ad 1) The surface sealing with C-S-H gel is induced by a chemical reaction of the compounds from the hydrated concrete and a unique combination of pure silicates. The reaction results in "sealing" porous structures in the concrete by silica C-S-H gel. As the chemical reaction is supported by the access of water, every further washing or sprinkling with water causes solution of the active components in the already loaded floor and the reaction can penetrate into considerable depth and, at the same time, it is induced repeatedly. This reaction is controlled and accelerated by means of a catalytic system of the latestgeneration, providing for significantly higher efficiency of the liquid silicate transformation into an amorphous gel structure, filling in both micro- and macropores of the cement composite, compared with non-catalysed systems. Also in this case, moistening of the cement product causes repeated activation of the catalytic system. This enables further penetration and ensures more and more durable treatment of the surface layers.
ad 2) The process of particles transformation and hardening is supported by active chemical components reacting mainly with low resistant particles on the cement product surface. This reaction supports the transformation of particles with low hardness to particles with significantly higher hardness, compared with the original status. This selective chemical reaction occurs not only on the surface of micro/macroparticles, but it also works on molecular level.
This results in surface hardening, dust-free floor surface layer and considerably higher hardness and surface resistance to abrasion, impact load, etc. Apart from that, the originally non-resistant micro- and macroparticles often exhibit easy solubility which can be described as washing particles out of the surface or dusting. Having applied FormulaForte, most of the water non-resistant particles are transformed into water resistant particles. Last but not least, the final surface shows much lesser absorption with no particles washout which contributes to the construction durability both in the interior and exterior, where the surface layer is exposed to chemical and defrosting substances.
