Short summary
In this work, the formation of natural magnesium silicate hydrate cement has been studied. The cement forms through the extraordinarily fast dissolution of quartz under high-pH, Mg-rich conditions that occur in south-east Norway where an ultramafic body is exposed. We studied the cemented rocks and the processes that led to the formation of the cement from the field scale to the nanoscale. Magnesium silicate hydrate cement might be a low-CO2 alternative to Portland cement.
