Swiss Firm Develops New Concrete Additive Thursday, January 5, 2017 A startup firm associated with a Swiss university says its newly developed additive can help to control many properties of concrete, leading to harder material that's slower to deteriorate. Kumar Abhishek, a doctoral student at Ecole Polytechnique Federale de Lausanne, in Lausanne, Switzerland, is CEO of Nanogence, a company with reported patents on a new, inorganic additive for concrete that it says can reduce the amount of concrete needed on a project, while extending a structure’s life. © 2016 EPFL Kumar Abhishek, a doctoral student at Ecole Polytechnique Federale de Lausanne, in Lausanne, Switzerland, is CEO of Nanogence, a company with patents on a new, inorganic additive for concrete. Abhishek performed research on the nanoscopic structure of concrete as part of his thesis work, according to EPFL. Using this concrete knowledge, he developed the additive, the chemical nature of which is a proprietary secret. The company says the single additive could take the place of a number of additives currently used to affect cure time and texture. Fighting Carbonation As the additive is inorganic, Abhishek says it can eliminate carbonation issues associated with carbon-based cement additives. Carbonation can lead to moisture infiltrating concrete and deterioration, as well as corrosion of the rebar that often reinforces structural concrete. Abhishek also says the additive creates harder concrete, which he notes could help reduce the amount of concrete needed to build a given structure. Abhishek is reportedly in talks with two European concrete producers to work on an additive specifically for white concrete, used in interior design, and is also working on an additive to help boost the insulative properties of concrete. “The idea is to eventually develop prefabricated elements that combine longevity with good thermal insulation,” he said. “Over 40 percent of energy worldwide is used for construction. Rethinking construction materials will hopefully enable us to reduce this usage.” Nanogence has been funded partly by grants from the European Venture Program and the Academia-Industry Program, as well as an Innogrant and an Enable grant , through EPFL.
