THE E-TECHNOLOGYa targeted mineralogy for optimal Ettringite formation

E-TECHNOLOGYOptimising Ettringite formation for outstanding

& predictable performance

Through its specific hydration process, the E-Technology is less affected by factors such as: varying climatic conditions, changing substrates’ quality, variable levels of impurities in other raw materials. The E-Technology is a most efficient route for ettringite formation, powering:

› Outstanding reactivity, for the fastest walk-on times and returns to service;› Superior stability and predictability of the drymix materials obtained.

The E-Technology comes in two versions: › TERNAL® EP, the Ettringite engine in Plain form› TERNAL® EV, the Ettringite engine with low Viscosity and built-in flow,

for reduced formulation complexity

For use in a wide range of both fluid and non-flow applications: from mid-range to high performance floor levelers, dry screeds, concrete repair compounds.

E-TECHNOLOGY

Specifically engineered for the development of binary formulations, the E-Technology embeds sufficient lime so that when combined with a suitable source of Calcium Sulfate, the correct stoichiometry for optimal ettringite formation is readily achieved – in the absence of Portland Cement.

E-TECHNOLOGYOptimising Ettringite formation for outstanding & predictable performance

A MOST EFFECTIVE HYDRATION PROCESS

Drymix mortars based on E-Technology binary binders show a single step hydration process pushed to a higher degree and a more homogenous hydration within applied thicknesses than materials based on common CA binder systems. All this comes from the more rapid dissolution rate coupled with the C12A7 phase, yielding quick and massive ettringite formation.

BENEFITING THE STABILITY& PREDICTABILITY OF THE MATRIXThis novel hydration process makes the E-Technology much less impacted by external factors. This gives rise to much more stable drymix materials with outstanding performance at early ages and better tolerance to temperature variations:

› Excellent placing properties: combination oflong and adjustable open time with prompt hardening, short time between the initial and the final set

› High early strengths› Very quick & self-drying› Robustness to varying climatic conditions
