The future of construction is sustainable. That future is what Imerys scientists recently exhibited at the Calcined Clays for Sustainable Concrete event in Lausanne, Switzerland with their white paper on low CO2 binder acceleration technology.
Meet Thiobacillus, a common bacteria found in marine and terrestrial habitats that oxidizes sulfur to generate sulfuric acid, in turn dissolving and corroding concrete and steel. Enter Sewper® Liner, Imerys’ most recent innovation designed especially for the protection of concrete elements of new wastewater infrastructure assets.
Calcium aluminate has been used in sewer environments since the 1940s. Initially, the drivers for its use included its resistance to sulfates in soil, rapid return to service and superior abrasion resistance.
Fonducrete® – an engineered calcium aluminate cement – is reducing costly maintenance and repair work in sugar mills.
Filtration is a commonly observed practice by winemakers across the world. For decades, minerals such as diatomite and perlite have played a vital role in the process – removing unwanted substances and leaving wine producers with clear, quality wines.
For years, virgin oils have been the in-demand ingredient in biofuels to help meet sustainability goals. Improved filtration techniques, thanks to minerals such as diatomite, mean even the most heavily contaminated waste fat can be used to run engines.
Specially treated diatomite, high-purity filter aids (HPFA) are used for solid/liquid separation in biotechnology and pharmaceutical applications.
