KARÇİMSA
AND ITS ACTIVITIES;
Karçimsa was founded with the objective of fulfilling regional
requirements by utilizing the slag waste product of Karabük
Steel Company (Kardemir) and to contribute to the national
economy. The facility was projected with an annual capacity
of 200,000 tons. The company was founded on 23 May 1996 with
“Akçansa Çimento Sanayıi ve Ticaret A.Ş.” holding 51 % and
“Kardemir Demir Çelik Sanayi ve Tic. A.Ş.” 49 % of the shares,
and cement production started on 12 March 1998.
At Karçimsa facilities, the clinker purchased from Akçansa
is ground together with the blast furnace slag acquired from
Kardemir to produce CÇ 42.5 Slag Cement. Even though the annual
capacity of the facility has been designed as 200,000 tons,
increasing this capacity twice fold is possible by choosing
the appropriate production variants.
