In recent years, the increase in studies and decisions on energy recovery and climate change has also
supported the increase in the measures taken against environmental pollution in the private sector.
Industrial establishments continue to develop various methods to reduce the energy consumption required for production activities and the environmental impacts that arise during production, as well as to strive tough competition conditions.
The CO2 emission that occurs during the production of clinker, which is a cement component, is one of the important factors of the total emission of cement production. Since the emission that will occur with the clinker ratio in the cement is directly proportional, the search for different raw materials and by-products has
emerged.
With the alternative products to be used in cement, CO2 emission, which we call greenhouse gas emission, is reduced and production is carried out with an environmentally friendly approach.
In this context, cement with additives has a positive effect on both the CO2 emission and healthier, safer, and more sustainable production activities through the mineral additives included in it.
Known as an alternative product; pyrite ash, foundry sand, iron dust, scale, bottom ash, boron mine, wastes, etc. are rich in minerals and there are no harmful components in their structures that can adversely affect cement properties, thus bringing great advantages in terms of use in cement production.
In particular, steps have been taken to ensure that Turkey is the leader in boron reserves with a rate of 72% and that this boron and its wastes are brought into the cement industry. It is known that the use of boron wastes in cement production reduces the amount of CO2 released into the air by 25-30%.
The use of boron waste as an additive in this sector also plays a life-saving role for the cement sector within the framework of the responsibilities brought by the Kyoto protocol.
When it is foreseen that the Urban Transformation works carried out in Turkey will increase in the future, the construction wastes (bricks, aggregates, etc.) to be obtained as a result of these applications will take place in the sector as important alternative products.
Recyclable products or wastes to be used as alternative products will provide great advantages to manufacturers in terms of both environmental and cost.
It is possible to use alternative products in the cement sector and then CE marking with the European Assessment Documents (EAD) prepared or to be prepared. EADs such as Aluminate Cement (EAD 150002-00-0301), fluor aluminate cement (EAD 150036-00-0301) can be given as examples for the use of slag in cement as a component.
Alternative products are used as a component in the cement industry, as well as as a mineral additive in concrete production. There are also prepared and published EADs for polymer-based additives (EAD 260006-00-0301), steel fibers from waste tires (EAD 260010-00-0301), bottom ash from various coals, and various types of slag.
In the absence of existing EADs within the scope of alternative products to be used, we as CPC prepare EADs and carry out our certification practice within the scope of these EADs. As CPC Certification Inspection Test Services, we continue to support the sector’s efforts to reduce this environmental approach and emissions by crowning it with our ETA and UTO studies.
