Ternary Systems with Portland Cement and Calcium Aluminate Cement
In the construction chemicals sector today, there is a requirement of offering different solutions for different demands (high temperature, early strength, fast setting, crack-free structure). As such, ternary systems are created using different ratios of Portland cement (PC), calcium aluminate cement (CAC) and calcium sulphate rather than using only Portland cement to prepare mixtures. Mixture […]
What is Chromium VI? How Does It Form in Cement?
Cr VI (Chromium 6) found in cement is followed by the sector due to its hazards on human health. According to European Parliament 2003/53/EC Directive, Cr(VI) content in cements used and sold in all the member countries is required to be no more than 2 ppm as of 17 January 2005. As of 3 January […]
What Are the Uses of Cement and Acid Admixtures? How Do They Work?
Cement-based repair mortars can be used for various purposes. Calcium aluminate cement can also be preferred as a repair mortar due to its suitable properties. Cement admixtures help optimize the performance of cement for specific applications. These admixtures can be either organic or inorganic compounds. In this article, we will discuss the use of organic […]
What is refractory? How To Use Calcium Aluminate Cement as Refractory? – III
Calcium aluminate cement is frequently preferred in refractory applications due to its performance and resistance to high temperatures. In the first article of our series, we examined in detail what refractory is — you can read that post here. The second article, which continued the series, focused on how calcium aluminate cement is used as […]
What is refractory? How To Use Calcium Aluminate Cement as Refractory? – II
Calcium aluminate cement can be preferred in field applications as an alternative to Portland cement. This is due to its distinct properties compared to Portland cement, depending on the intended use and performance requirements. The key difference between calcium aluminate cement and Portland cement lies in the distinct hydration products they form. This difference significantly […]
What is High Performance Cement?
High performance cements are used for special purposes in order to eliminate some of the problems encountered in reinforced concrete structures. Calcium aluminate cement, which provides ease of use with its early setting time, is preferred due to its high resistance to groundwater. Sulfate Resistant Cements, Oilwell Cements specially designed for oil wells, and Calcium […]
What is a refractory material?- I
Concrete is the most important material used in the construction sector. However, its strength decreases when concrete is subjected to high temperatures. In the event of temperatures over 200 °C, significant damage starts to occur in the structure of concrete and its service life shortens. Therefore, other materials must be used in production conditions including […]
Construction Chemicals: Applications
The construction chemicals industry is one of the most important sectors in terms of achieving energy efficiency with sustainable structures in the construction sector. The most important products in the construction chemical market are undoubtedly cement blends. Çimsa Cement has an extensive product offering used in many areas of the construction chemicals sector including concrete, […]
White Cement Based Ceramic Adhesives and Cellulose Ether II
In the first part of our article, we explained the properties of cellulose ether, its usage in cement-based mortars and water retention mechanism. We examined the characteristics of both cellulose ethers and cement types in order to see the interaction of cellulose ether types with different cements. We compared different cement types in physical, chemical, […]
White Cement Based Ceramic Adhesives and Cellulose Ether
In terms of cement-based dry mixtures produced for structure chemicals, cement is important as are other inputs. Many minor inputs such as polymers, celluloses, water-repelling agents, plasticizers, etc. contribute to the performance of the mixture and help to create durable mortars. One of the most important additives of this kind is cellulose ether and it […]
