Effect of chemical composition of clinker on grinding energy requirement

Fifteen commercial Portland cement clinker samples with a wide range of chemical compositions were subjected to grinding tests and relationships between grinding energy requirement attained specific surface areas and various chemical parameters were found. Regression analyses of the test results revealed that the energy-fineness relationship is exponential, and grinding energy is correlated with Al2O3, free CaO, liquid phase contents, silica moduli, and (C3S + C2S)/(C(3)A + C(4)AF) ratios of the clinkers.


Effects of walnut shells on the rheological properties of water-based drilling fluids
Iscan, A.G.; Kök, Mustafa Verşan (2007-08-01)
In this research, three different water-based drilling fluids were prepared according to American Petroleum Institute (API) standards, and effects of walnut shells on the rheological properties of the samples were studied. The walnut shells of 2-, 4-, and 6-mm samples and their equal weight mixtures of 2-4 mm and 4 6 mm were added to the drilling fluid samples in different concentrations. The aim of this study is to determine the optimum walnut shell size, concentration and polymer concentration to minimize...
Effect of different clay concentrations on crude oil combustion kinetics by thermogravimetry
Kök, Mustafa Verşan (2010-03-01)
The objective of this research was to investigate the effect of different clay composition and concentrations on the thermal behaviour and kinetics of heavy crude oil in limestone matrix by thermogravimetry (TG/DTG). In TG/DTG experiments, three distinct reaction regions were identified in all of the crude oil + limestone mixture known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO) respectively. Addition of clay to porous matrix significantly affected the react...
Effect of Polymers on the Rheological Properties of KCl Polymer Type Drilling Fluid
Kök, Mustafa Verşan (2005-05-01)
In the course of this research, the effect of two polymers (xanthan gum and polyanionic cellulose) on the rheological properties of KCl/polymer type drilling fluids was investigated. Non-Newtonian drilling fluids are conventionally characterized by rheological models (Bingham Plastic, Power Law, Casson, Herchel-Bulkley and Robertson-Stiff). In this research, forty-five KCl/polymer data sets of varying compositions are prepared. Polymer addition to the system has affected the model and caused a variation of ...
Effect of pressure on combustion kinetics of heavy oils
Bağcı, Ali Suat (Informa UK Limited, 2005-07-01)
In this study, 16 experiments were conducted to study the effects of pressure on crude oil oxidation in limestone medium. Karakus (29 degrees API), Beykan (32 degrees API), Bati Raman (12 degrees API), Camurlu ( 12 degrees API), Adiyaman (26 degrees API), Garzan (28 degrees API) and Raman (18 degrees API) crude oil from Turkish oil fields were used. The mixture of limestone and the crude oil was subjected to a controlled heating schedule under a constant flow rate of air. The produced gas was analyzed for i...
Effect of spraying rate on microstructure of spray deposited Al-Fe-V-Si alloy
Kalkanlı, Ali (Informa UK Limited, 2003-12-01)
In this study gas atomisation and spray deposition of a series of AlFeVSi alloys were carried out. Traces of transient liquid were observed as lamellar structure in the middle of the specimen. The heat transfer conditions of this structure were modelled by finite difference calculation. Metallographic specimens for optical microscopy were prepared from the preforms formed in these processes. Optical microscopy showed the presence of dispersoids in the specimens. The dispersoids were characterised as AlFeVSi...
