Developed units: Concrete additives and nanoadditives

Gaia

Like the old Greek Earth Goddess took care of her children, Gaia takes care of the environment and operators´ health , It was the first concrete additive that replaced the microsilica.

Gaia additive surpassed the expectations of its design and gave concrete not only the high initial and final resistance but in addition, plasticity, impermeability, minor final cost of work, and cement savings of up to 40%. Also, it lowered the levels of environmental contamination.

In addition, a liter bottle of Gaia equals a whole barrel of microsilica, extra cement and superplasticizers. If before a 2 meters thick beam was required to hold a bridge correctly, now only 75 cm are required. If before 28 days were necessary in order to achieve compressive strengths of 80MPa, now only 1 day is required. The prestressed beams that before required 3 days to be ready and needed to be cured with water to the steam , now require only 1 day and they do not need water.

Moreover, Gaia became one of the first indicators of the properties that the next commercial nanocements in the market will have: nanoparticles of silica turn into nanoparticles of cement (nanocement) in the chemical reactions that take place in the setting of the concrete, Thanks to all these advantages, the entrance of nanosilica Gaia into the market modified the concept of what is possible and what is not in this field.

Since 2004, "El Teniente", the greatest copper underground mine of the world, has been using Gaia for its concrete and the use of the microsilica in this deposit has been prohibited. Also, in March 2007, Prefabricados Andinos (PREANSA), started to use Gaia too.
