Tecnochem Italiana S.p.A.

Additive based on condensed silica fume which, once mixed in the concrete, creates micro-particles of a size between 0.01 microns and 1 micron and this allows specific surfaces ("finesse") of 20,000 m² per kg (against 300 m²/kg of cement). Very high reactivity with the components of the hydration of the cement with the formation of calcium silicates. To be used always  together with poly-carboxylate or poly naphthalene sulphonate based super-plasticizers for obtaining compact and impermeable concrete, with capillary porosity tending to zero, super mechanical strength, high resistance to environmental and chemical attack. The version MICROBETON POZ/VEX1/80-20 (grey) is specially formulated for the rheodynamic functionality in self-compacting concrete and for obtaining perfect fair-faced concrete.

Additive reducing the drying and autogenous shrinkage an consequence of the decrease of the attraction forces between the solid surfaces by the water meniscus in the Nano capillaries of the concrete

Powder product consisting of alkali earth oxides treated in order to allow the reduction or elimination of the shrinkage of the concrete. With this characteristic also the possibility is combined to realize concretes with exceptional physical-mechanical characteristics, using in combination with a super-plasticizer TECNOS. The product exhibits an expansion capacity that takes place mainly in the first 24/48 hours
