CONCRETE HARDENER H35<\/strong><\/h1>\n
Concrete Hardener H35 is a treatment for concrete and cement surfaces in general, permanent, CONSOLIDATING, HARDENING and ANTI-SALT.<\/strong><\/h5>\n<\/div><\/div>

PRODUCT DESCRIPTION<\/strong><\/span>
\n<\/strong><\/h2>\n<\/div><\/div>
\"barra<\/div><\/div>
Concrete Hardener H35 is used in several industrial, construction and environmental applications. Its characteristics mean that it can be used as a fire retardant (increasing the critical temperature of the treated material), as a hardener, as a binder and accelerator of chemical reactions in concrete, but also as an insecticide, acaricide, fungicide or whitener.
\n<\/strong><\/h5>\n
Concrete Hardener H35 <\/strong>is a water-based, odourless and non-toxic product. When penetrating the substrate, it reacts chemically to generate an extremely solid structure in the capillaries, making the substrate and its alkaline environment stable over time and resistant to the migration of chloride ions, carbonation, the aggression of run-off acid water.<\/h5>\n
Concrete improves considerably, both in appearance and technical features, <\/strong>through surface treatment with Concrete Hardener H35. This penetrates into the porosity of the substrate, chemically reacts with Ca(OH)2, produced by the hydration of the cement to form calcium silicate hydrate.
\nThe impregnation of the pores, besides improving aesthetics, drastically reduces the permeability to water, but not to vapour, increasing the surface hardness, the durability of the concrete and in particular the resistance to acid aggression. <\/strong>By allowing humidity to escape, risks due to the freeze-thaw cycle are avoided.
\n<\/strong><\/h5>\n
Concrete Hardener H35 <\/strong>penetrates into the porosity of the cement and, the very first application completely invades all the porosity, even capillary, reacting with Ca++ ions as mentioned above. The formed gel slowly contracts by 20% leaving the pores filled with 80% of the initial volume. After the second application, the pores remain empty for 20\u00d70.2 = 4% and full for 96%. After the third application, the pores remain empty for 20%\u00d74 = 0.8% empty and full for 99.2%, i.e. practically full and therefore inaccessible to liquids. The silicate anions contained in Concrete Hardener H35 react with the calcium ions present in the hardened cement, forming a silicate calcium gel resistant to water and other liquids, depending on the reaction: Ca++ + SinO2n+1 -> CaO \u2219 SinO2n+1. This reaction occurs inside the pores of the cement. The Ca-silicate gel clogs the porosities, making the cement waterproof to liquids and at the same time harder, more resistant to wear, insensitive to carbonation and more resistant to the aggressive action of acids.

Concrete Hardener H35 exerts an anti-corrosive action on metals <\/strong>that it comes into contact with, such as concrete reinforcement.
\n<\/strong><\/h5>\n
The Concrete Hardener H35 in contact with metals forms monomolecular films of metallic silicates, impervious to oxygen and acids and therefore acts as anticorrosive. The Concrete Hardener H35 is able to penetrate into the capillaries of the concrete thanks to its low viscosity and especially low surface tension that sets it apart from other products that you can find on the market. Thanks to its features, Concrete Hardener H35 penetrates deeper and allows you to achieve excellent waterproofing.
