There are similar to 6700 million tons of perlite reserves in the world and two thirds of this amount takes place in Turkey. Although perlite possesses pozzolanic properties, it has not been so far used in producing blended cements. This study focuses on the use of natural perlites in blended cement production. For this purpose, after examining the suitability of the perlites as pozzolans and their case of grindability, 16 types of blended cements having 320 m(2)/kg or 370 m(2)/kg Blaine fineness were produced by using 20% or 30% perlite additions. Production of the blended cements were accomplished either by intergrinding or separate grinding. The performance of the cements was evaluated by conducting the following tests: particle size distribution by laser diffraction, normal consistency, setting time, soundness and compressive strength. The results showed that perlites possess sufficient pozzolanic characteristics to be used in production of blended cement.

Mechanical Properties of Cement Mortar Containing Heat-Treated Boron Derivative Waste at Elevated Temperatures KAMAN, DERYA ÖVER; Koroglu, Levent; AYAS, ERHAN; Tokyay, Mustafa; GÜNEY, Yücel (2018-06-01) The largest boron reserves in the world are located in Turkey. The production of boron compounds and use of generated boron derivative waste during this production are extremely important for both economically and environmentally. This study evaluates boron derivative waste and investigates doping effects of heat-treated boron derivative wastes on mineralogical, microstructural, and mechanical properties of cement mortar. The waste, portland cement, and wastes heat-treated at temperatures of 400-900 degrees...
USE OF SEA-WATER IN THE FLOTATION OF CARBONATE RICH SEDIMENTARY PHOSPHATE ROCK Özbelge, Hilmi Önder; ALFARISS, TF; ABDULRAZIK, AM (Springer Science and Business Media LLC, 1993-01-01) There is an appreciable amount of carbonaceous sedimentary phosphate deposits in the northern Africa and the Middle East which are expected to gain importance in the near future because of the depletion of the deposits in Florida. In many of the regions where phosphate deposits are found there is a shortage of fresh water, and sea is not very far. The use of sea water instead of fresh water in flotation of carbonaceous phosphate rock is successfully demonstrated. Thus an appreciable reduction in the operati...
Investigation of Large Scale Slope Failure Mechanisms and Numerical Modeling for the Safe Design of Slopes in a Lignite Mine Tutluoglu, LEVEND; Karpuz, Celal (2008-07-24) With about 9.3 billion tons of reserve, lignite is a major source for energy production in Turkey. Turkish Coal Enterprises (TKI) produces about 60% of the yearly lignite production capacity. Can Surface Lignite Mine which is planned to produce approximately 2.5 million tons of 3000 kcal/kg coal, will be one of the main production areas of TKI. Possibility of large scale slope failures and their negative effects on mining operations in large Can Lignite Surface Mine on the northwestern Turkey were the major...
Kinetic analysis of central anatolia oil shale by combustion cell experiments Iscan, A. G.; Kök, Mustafa Verşan; Bagci, A. S. (Springer Science and Business Media LLC, 2007-06-01) In this study, four oil-shale samples (Nigde-Ulukisla) excavated from Central Anatolia Turkey were analyzed where this region is believed to have a high potential of oil in its shale rich outcrops. The samples (similar to 40 g) were combusted at 50 psi gas injection pressure, at an air injection rate of 1.5 L min(-1) in a combustion-reaction cell. All the experiments were conducted up to 600 degrees C. The percentages of oxygen consumption and carbon monoxide and carbon dioxide production were obtained inst...
Geological Considerations for the Economic Evaluation of Turkish Oil Shale Deposits and Their Combustion-Pyrolysis Behavior Kök, Mustafa Verşan (Informa UK Limited, 2010-01-01) The oil shale deposits in Turkey are widely distributed in middle and western Anatolia. Turkish oil shales are of Palaeocene-Eocene and middle upper Miocene age. Current reserves of oil shales are approximately 2,220 million tons (total reserve) and mainly are located in Himmetoglu, Seyitomer, Beypazari, and Hatildag deposits. Some petrological, geochemical, Fisher Assay, and fluidized combustion tests are performed for these oil shale fields, and it was concluded that Himmetoglu oil shale is the most appro...
