The ash obtained from central Jordanian oil shales was subjected to standard tests to evaluate its effectiveness as an admixture in reducing mortar or concrete expansion due to alkali-silica reactions. According to the results obtained with Pyrex glass aggregate, the ash only partially complied with the specified requirements but still performed better than two locally available pozzolanic admixtures. The ash was also helpful in reducing the expansion of mortars containing a local chert aggregate. Considering the existence of high-alkali cements, potentially reactive aggregates and large oil shale reserves in Jordan, the findings of this study would further encourage the utilization of the oil shale ash as a pozzolanic admixture in mortar or concrete.

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 ...
Improved oil recovery application in limestone reservoirs using alkaline solutions Bagci, S.; Kök, Mustafa Verşan; Turksoy, U. (Informa UK Limited, 2007-09-01) In this research, the effect of sodium hydroxide (NaOH) and sodium silicate (NaSiO4) solutions for the improved oil recovery of Raman crude oil was investigated using a one-dimensional unconsolidated limestone reservoir model. The results of displacement tests showed that sodium hydroxide (NaOH) and sodium silicate (NaSiO4) solutions were not effective on incremental oil recovery. It was also observed that injection flow rate of alkaline solution has minimum effect on Raman crude oil in scope of oil recover...
Activities of copper oxide and Cu-V and Cu-Mo mixed oxides for H2S removal in the presence and absence of hydrogen and predictions of a deactivation model Yasyerli, S; Dogu, G; Ar, I; Doğu, Timur (2001-11-14) Considering the importance of high-temperature removal of H2S from industrial gases, sorption studies were carried out on copper oxide and Cu-V and Cu-Mo mixed oxides in the absence and presence of hydrogen in a fixed-bed reactor. Experiments were carried out in a wide temperature range between 300 and 700 degreesC. A significant amount of SO2 was produced with CuO sorbent in the absence of hydrogen. In the case of mixed oxide sorbents, SO2 formation was detected even in the presence of hydrogen. On the bas...
Effects of separate and intergrinding on some properties of portland composite cements Soyluoğlu, Serdar; Tokyay, Mustafa; Department of Cement Engineering (2009) 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 pro...
Application of ADM1 model to a full-scale anaerobic digester under dynamic organic loading conditions Ozkan-Yucel, U. G.; Gökçay, Celal Ferdi (2010-01-01) The IWA Anaerobic Digestion Model No. 1 (ADM1) was used to simulate the full-scale anaerobic sludge digester of Ankara Central Wastewater Treatment Plant. The digester is a completely mixed, once through continuous flow type which is being fed with a primary and secondary sludge mixture. The variability and unpredicted nature of the primary sludge composition was expected to challenge the model. A one-year dynamic data set from the digester was used for model calibration and validation in the study. The sta...
