Vicat and Materrup launch raw clay cement joint venture

24 March 2023

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.

Materrup to establish second cement-free concrete plant at Bordeaux

05 April 2022

France: Sustainable concrete producer Materrup has shared plans for its upcoming Bordeaux precast concrete elements plant. The L’Usine Nouvelle newspaper has reported that the facility will produce precast elements from Materrup’s cement-free concrete, which it produces from uncalcined clay, an activator and a precursor at room temperature. The technology, called Clay Cement 1 (MCC1), reduces CO2 emissions by 50 – 80% compared to ordinary Portland cement (OPC), according to the producer. It previously opened a Euro7m 50,000t/yr plant in the Atlantisub Business Area in Saint-Geours-de-Maremne, Nouvelle-Aquitaine.
