France: Vicat and Materrup have formed a joint venture to industrialise production and accelerate marketing of Materrup’s Clay Cement 1 (MCC1) raw clay cement. The Le Moniteur newspaper has reported that the technology is based on a precursor and activator mixture which removes the need for calcination of the clay. Materrup said that this halves MCC1 cement’s CO2 emissions compared with ordinary Portland cement (OPC).
The partners say that clay has better long-term feasibility than other alternative raw materials for cement production, because global reserves are currently 2Tnt.
