In practice, in the mineral industry sector, thermal processes trigger new developments to improve their efficiency and incorporate new primary and secondary materials.<\/p>\n

The CTP is working on a number of research projects in this area, including new compositions of clinker. It has available laboratory and pilot equipment including several rotary furnaces and will in the near future construct a clinkerisation furnace allowing its field of investigations to be widened.[\/vc_column_text]\n
