Slag cement, which is highly resistant to chemical attacks due to its structure, has low hydration heat, is known to be more durable than CEM I type portland cement in the long term, can be used in dams, ports, treatment plants, irrigation channels, bridges and many other projects, and it is increasingly more preferred. In addition, this product, which requires much less clinker usage, is the type of cement that has the least damage to the environment under today’s conditions. Slag cement reduces concrete costs and increases strength. Concrete containing blast furnace slag cement, less permeable, low hydration, better workable and workable, higher strength, more resistant to hazardous chemicals and harmful attacks in many forms than normal concrete. CEM III / A type product contains 36-65% slag, while CEM III / B type product contains 66-80% slag.
