Sublime Cement™

Sublime Cement™ is a carbon-neutral alternative to ordinary Portland cement (OPC). Sublime’s novel cement process uses electrochemistry to extract reactive calcium (Sublime Lime™) and Silicates from abundant raw materials that are then blended into a final cement. In the electrochemical process, entire parts of non-carbonate rocks are converted into cement at ambient temperatures. The process uses carbon-free feedstocks and low temperatures, thus, Sublime Cement does not emit CO2. This cement is a drop-in replacement for OPC, meeting or exceeding construction performance standards. Sublime cement is the first zero-carbon emission cement process without relying on carbon capture, utilization, or storage.
