What are the benefits of Lithium Based densifiers and concrete hardeners?
Lower viscosity and alkalinity allows C² lithium hardeners to achieve deeper and more complete penetration. This creates a denser, harder bond, leaving far fewer un-reacted calcium hydroxide molecules with a wider distribution of lithium particles during absorption.
Smaller molecules of lithium make the reaction more even and consistent, creating a denser surface. On the other hand, sodium and potassium densifiers react inconsistently and irregularly, leaving clusters of calcium hydroxide, reacted and un-reacted, spread throughout the concrete surface resulting in a weaker, irregular bond. This is the basis for a potential problem if moisture should penetrate into the concrete substrate, initiating an Alkali Silica Reaction (ASR).
C² lithium hardeners react with calcium elements in concrete, building strong and very stable silicate structures, maximizing and extending lithium reactivity. C² lithium hardeners also react with calcium hydroxide covering the substrate, forming complex tri-calcium silicate compounds that keep moisture out. These compounds block the micro pores in concrete, practically eliminating moisture absorption into the concrete substrate. Although these reactions are common to most surface densifiers, C² lithium hardeners react more completely and evenly than sodium and potassium.
C² lithium hardeners will not contribute to map cracking or crazing and will not form silica gel to seal the concrete surface like sodium and potassium hardeners.
C² lithium hardeners will not absorb water like sodium or potassium and are less water-soluble. Thus the concrete is more water resistant.
C² lithium hardeners will prevent or reduce Alkali Silica Reactivity (ASR). Silica in the aggregate reacts with alkalies in hydrated cement to form a gel that expands when water is introduced. This reaction produces huge pressures that cause cracks to develop in concrete – cracks that lead to accelerated deterioration of the surface protective layer. These cracks and micro-cracks allow water to penetrate into the substrate, causing corrosion of reinforcing steel, freeze thaw damage, and other problems. C² lithium hardeners will help keep moisture out of the substrate and prevent occurrence of a chemical reaction between alkalies, silica and moisture. ASR reactions will not occur without water.
Sodium and potassium hardeners directly contribute to the ASR issue by the very nature of adding potassium and sodium into the concrete. Lithium based C² hardeners, using a sophisticated and proprietary chemistry, are free of potassium and sodium. C² densifiers deliver lithium components into the concrete substrate as opposed to potassium and sodium.

Strengthening of Floor Surface
C² liquid hardeners/densifiers are chemicals heavy in silica, which reacts with calcium hydroxide in the concrete to fill pores, strengthen and harden the surface wear layer.
C² liquid hardeners/densifiers also contain a highly reactive lithium catalyst, which helps to achieve much greater penetration into the floor surface and triggers a much faster and more complete reaction with the concrete.
Greater Abrasion Resistance
Even the most perfect bare concrete floors will wear off relatively easily in an industrial traffic conditions. Floors treated with C² liquid hardeners/densifiers will significantly improve abrasion resistance.
C² liquid hardeners/densifiers will outlast topcoats. A permanent impregnation of the floor surface can be achieved for life of the concrete with one single application.
Elimination of Dusting from Efflorescence
In ordinary concrete, tiny particles of dust are pushed to the surface through an upward force called hydrostatic pressure, resulting in efflorescence. Efflorescence leads to dusting. C² products eliminate efflorescence and prevent dusting with one single application.
A treated floor surface, though shiny, does not create a slippery floor.
Improved Condition for Old Floors
As concrete ages, surface stress, delamination, curled cold joints, and other problems can arise. C² liquid hardeners/densifiers combined with our customized grinding and polishing technique can remove the top surface layer of the old concrete and strengthen the floor, increasing it’s impact and abrasion resistance.
Reduced Tire Wear
The rough, uneven texture of natural concrete causes tires to abrade, adding to their wear. A concrete floor treated with C² liquid hardeners/densifiers will make the entire surface smooth, preventing this abrasion and leaving minimum tire marks on the floor surface. Ordinary cleaning can easily remove these surface blemishes.
Little or No Production “Down Time”
Your floor can be put into service immediately after the application process is complete. Due to the cleanliness of the process and the lack of toxic or hazardous chemicals, floors can often be serviced while the plant is in full production.
Most floor systems, including tile and linoleum, require aggressive scrubbing to maintain a clean environment and nice appearance. Surfaces treated with C² liquid hardeners/densifiers are tightly compacted – reducing stains – and do not require any waxing or stripping to maintain the sheen.
Improved Reflectivity and Ambient Lighting
The reflective properties of a densified floor surface, increases the lighting in facilities. Increased ambient lighting will reduce energy bill as well as aesthetically pleasant.
