Brimstone products

Brimstone's deeply decarbonized process is a breakthrough in cement production, making industry-standard portland cement with carbon-free calcium silicate rock instead of limestone. Brimstone cement is chemically and physically identical to conventional portland cement, with the same quality and performance builders have trusted for over 150 years. Simply put, our process will turn cement, one of the most intractable climate problems, into a climate solution. It all starts with a new kind of rock.
