The product is the result of a six-year collaboration between LaFargeHolcim and Solidia and uses a special binder — produced at lower temperatures — and patented curing process that uses CO2 rather than water. By adding and absorbing CO2, Solidia Concrete reaches strength in less than 24 hours unlike precast concrete made with Portland cement, which takes 28 days to reach strength. — Construction Dive
Construction Dive takes a look at a new business venture launched by LafargeHolcim and Solidia Technologies that will bring carbon-sequestering precast concrete production capabilities to the United States.
The new Solidia Concrete product, according to the companies, cures in less than 24 hours through a patented process that pulls carbon dioxide from the atmosphere. Typically, conventional Portland cement-based concrete cures with water and takes nearly 30 days to reach its final strength. The product's first commercial venture will supply EP Henry’s paver and block plant in New Jersey with the reduced CO2 cement, according to a press release.
According to Construction Dive, the new concrete can potentially reduce the carbon footprint of precast concrete by 70 percent.
