Solidia showcases low-carbon cement and concrete

Products reduce CO₂ emissions by 70 percent.

Solidia Technologies was showcased as a visionary leader advancing sustainable solutions for industry during the annual Cement Industry Suppliers’ Forum (CSIF), which brings together frontrunners in the sector and leading field publications.

Solidia’s presentation included results of multiple tests of Solidia Cement-based concrete that demonstrated the performance, properties and added value associated with the technology, including its impact on reducing the carbon footprint of cement and concrete.

“Solidia’s novel chemistry allows manufacturers to use the same raw materials and the same mixing and forming processes to create a product that reduces CO₂ emissions by 70 percent,” reported Solidia Technologies Project Manager Devin Patten, who presented at the conference. “Solidia Concrete™ also recycles water, since it cures through carbonation, not hydration. This curing process takes days, not weeks.”

Led by the British Cement Association (now MPA Cement), the CISF convenes annually to allow representatives of cement companies and their suppliers to update themselves on relevant technical, economic and regulatory developments and renew industry contacts. This year’s forum attracted chemists, students, researchers and leaders from the construction, concrete and concrete products manufacturing and related industries across the UK.

Solidia Cement, which is silicate-based and has a low-calcium content, gains strength through carbonation instead of hydration. Solidia Concrete is more durable with shorter curing times, using the same raw materials and existing equipment as traditional concretes. Carbon emissions are reduced up to 70 percent in the production of Solidia Cement and Solidia Concrete combined.

Currently in commercialization for large- and small-scale applications, Solidia’s R&D collaborators include LafargeHolcim, The Linde Group, CDS Group, DOT’s Federal Highway Administration, DOE’s National Energy Technology Laboratory, the EPA, Rutgers University, Purdue University, Ohio University and the University of South Florida.
