In the production of cement, to increase the cement/clinker ratio and decrease CO2 emission, the most important alternative is to produce mineral admixture incorporated cements (CEM II-III-IV-V) instead of portland cement (CEM I). These cements are usually produced by intergrinding the portland cement clinker and the mineral admixtures. However, the difference between grindabilities of the different components of such cements may cause significant effects on the particle size distribution and many other properties. For this reason, separate grinding of additives and clinker may be thought as an alternative. In this study, the effects of intergrinding and separate grinding on the particle size distribution and consequently on the strength of portland composite cements which contained natural pozzolan (trass), granulated blast furnace slag (GBFS) and limestone besides portland cement clinker were studied.

A study on blended bottom ash cements
Kaya, Ayşe İdil; Yaman, İsmail Özgür; Hoşten, Çetin; Department of Cement Engineering (2010)
Cement production which is one of the most energy intensive industries plays a significant role in emitting the greenhouse gases. Blended cement production by supplementary cementitious materials such as fly ash, ground granulated blast furnace slag and natural pozzolan is one of the smart approaches to decrease energy and ecology related concerns about the production. Fly ash has been used as a substance to produce blended cements for years, but bottom ash, its coarser counterpart, has not been utilized du...
Effect of mixture proportioning on the strength and mineralogy of magnesium phosphate cements
Bilginer, Baki Aykut; Erdoğan, Sinan Turhan (Elsevier BV, 2021-3)
Magnesium potassium phosphate cement (MKPC) has properties advantageous over ordinary portland cement such as quick setting and rapid strength gain. Although the effect of mixture proportioning on MKPC pastes has been studied, there are conflicting reports on how calcination of magnesia, parameters like magnesium-to-phosphate ratio (M/P) and water-to-binder ratio (W/B), added materials like borax and fly ash, or the addition of sand influence mineralogy and properties like setting and strength. These factor...
Properties of alinite cement produced by using soda sludge
Kesim, Asli Gunes; Tokyay, Mustafa; Yaman, İsmail Özgür; Öztürk, Abdullah (2013-04-01)
A production route of alinite cement clinker using the waste material of the Solvay process of the soda industry as the main raw material was searched. Soda sludge (73.5 wt%), clay (26.3 wt%) and minor amounts of iron ore (0.2 wt%) were mixed to obtain a raw mix that is later burned at nine different burning schemes. Four different burning temperatures (1050, 1100, 1150 and 1200 degrees C) and three different burning durations (60, 90 and 180 min) were applied for clinkerisation. The clinkers obtained were ...
Comparison of the strength developments of interground and separately ground marble-incorporated cement mortars
Kava, İsmail Tolga; Erdoğan, Sinan Turhan; Hoşten, Çetin; Department of Cement Engineering (2013)
Production of Portland cement clinker contributes significantly to global warming and has a large environmental footprint. To reduce the amount of kiln-produced clinker in cement, the use of substitute natural or industrial waste materials has been gaining popularity. The use of CaCO 3- containing natural materials such as limestone and waste marble pieces has been increasing around the world, particularly after modifications made to cement production standards. Two types of marble-containing blended Portla...
Investigation of the properties of portland slag cement produced by separate grinding and intergrinding methods
Geven, Çağlar; Hoşten, Çetin; Department of Cement Engineering (2009)
In recent years, there has been a growing trend for the use of industrial by-products in the production of blended cements because of economical, environmental, ecological and diversified product quality reasons. Granulated blast furnace slag, a by-product of the transformation of iron ore into pig-iron in a blast furnace, is one of these materials which is used as a cementitious ingredient. The aim of this study is to investigate the properties of Portland slag cement (CEMII/B-S) by using separate grinding...
