2013 R&D 100 Winner
Concrete is the second most utilized substance on Earth, after water. More than 30 billion tons of concrete are manufactured each year, and Portland cement (PC) is the primary binder used in the production of concrete. However, regulatory pressure is forcing significant reductions in carbon dioxide emissions from the concrete industry. Process steps result in emissions of approximately 800 kg of carbon dioxide for each ton of cement produced.

Solidia Cement, a replacement for traditional PC binders from Solidia Technologies Inc., is intended to reduce these emissions through the use of calcium metasilicate that can either be naturally mined or synthesized by solid-state reaction at lower temperatures than traditional methods. Research at Rutgers Univ. provided the foundation for mineral carbonation, and supported the theoretical work in developing the process for synthesizing this mineral on a PC kiln. The reduced emissions associated with Solidia Cement production and the carbon dioxide sequestration associated with Solidia Concrete curing combine to reduce the lifecycle emissions of concrete by 60%.
