This year Mykolaivcement has started producing blast furnace cement BFC ІІІ/А-400

This year Mykolaivcement has started producing blast furnace cement BFC ІІІ/А-400, a universal cement with increased resistance to aggressive environments that is intended for common structures and works in the hot season.  

Active mineral additives improve the physical and mechanical properties of both the cement itself and the concrete made from it. The presence of blast furnace granulated slag in cement helps to reduce the hydration temperature, which decreases the temperature difference during the construction of solid structures, and, as a consequence, reduces the risk of cracking. High workability is achieved by slowing down the process of setting blast furnace cement and a lower hydration temperature. This increases the time for transporting the mortar to the site and facilitates work in the hot season.  

Slag increases the resistance of cement stone to aggressive environments: sulfate resistance, acid resistance, resistance to alkaline aggression, resistance to seawater, to carbonization, etc., due to a reduced content of hydration products of the aluminate phase of Portland cement clinker in the cement stone.  

Our technical marketing experts recommend using this cement for:  

  • foundations in aggressive waters;  
  • cast-in-place structures;  
  • non-pressure pipes;  
  • arrangement of screeds, floors, paths indoors and outdoors;  
  • hydraulic and sewer structures;  
  • basins;  
  • dams. 

Cement with active mineral additives is our step towards sustainable development. The use of active mineral additives in the production of cement contributes to solving a number of environmental problems, which points to the corporate social responsibility of both the cement manufacturer and its consumers:  

-Clinker production releases carbon dioxide, which is a major cause of global warming. Substituting a part of clinker in cement with active mineral additives helps to reduce the negative impact of the cement industry on the environment.  

-Blast furnace slag, which is a by-product of metallurgy, is disposed of in dumps, which require large areas of land. Therefore, the use of slag in cement production ensures integrated use of industrial waste, reduces dump areas, and decreases environmental pollution. Replacing clinker with blast furnace granulated slag reduces the extraction of raw materials from which it is made.
