To manufacture  CEM I 42.5 Portland  cement,a  precisely  specified  mixture of raw materials containing limestone,marl,
iron  ore  and  bauxide  is  burned.The produced clinker,together  with  calcium sulfate to control setting,is then ground to
produce  cement  of  the  required  fineness.Up to 5%  of  minor  additional  constituent (limestone) is incorparated at the
rinding stage. CEM I 42,5 R  is  made  from  the same clinker as CEM I 42,5 N but CEM I 42,5 R is more finely ground in
order  to  promote  greater  reactivity.Therefore, CEM I 42,5 R delivers higher early strength without  significant reduction
of setting time.This type of cement is suitable for applications of prefabricated house , pre-tension concrate,art structures
and cast-tunnel applications which are common at the present day at gross house buildings.
