This paper reports the composition and properties of highly flowable self-consolidating concrete (SCC) mixtures made of high proportions of cement replacement materials such as fly ash and pulverized limestone instead of high dosage of a plasticizing agent or viscosity-modifying chemical admixtures. Self-consolidating concrete mixtures are being increasingly used for the construction of highly reinforced complex concrete elements and for massive concrete structures such as dams and thick foundation. In this study, by varying the proportion of portland cement (OPC), Class F-fly ash (F), and limestone powder (L), SCC mixtures with different strength values were produced, and the properties of both fresh and hardened concrete were determined. For a comprehensive analysis and quantification of emissions and global warming potential (GWP) from concrete production, life-cycle assessment (LCA) was employed. We find that high volume, up to 55% by weight replacement of OPC with F, or F and L produces highly workable concrete that has high 28-day and 365-day strength, and extremely high to very high resistance to chloride penetration along with low GWP for concrete production.

Strength and Durability of Composite Concretes with Municipal Wastes Tokgoz, D. Deniz Genc; Ozerkan, N. Gozde; Kowita, O. Samir; Antony, S. Joseph (2016-09-01) The influence of different types of polyethylene (PE) substitutions as partial aggregate replacement of microsteel fiber-reinforced self-consolidating concrete (SCC) incorporating incinerator fly ash was investigated. The study focuses on the workability and hardened properties including mechanical properties, permeability properties, sulfate resistance, and microstructure. Regardless of the polyethylene type, PE substitutions slightly decreased the compressive and flexural strength of SSC initially; howeve...
Hydration and properties of limestone incorporated cementitious systems Erdoğdu, Korhan; Tokyay, Mustafa; Department of Civil Engineering (2002) As limestone is a new widely used mineral addition in cement, understanding the effects of this material on cement properties and hydration in a detailed manner is of substantial importance for efficient and proper usage. Consequently, the current study is designed. In the experiemental study, three different limestones were used. The aim of using different limestones is to reach broad generalisations by crosschecking the results and compare the effects of limestones with different structures. These limesto...
Gas mixing in conical spouted beds Doğan, Neslin; Külah, Görkem; Department of Chemical Engineering (2020-12-28) Conical spouted beds are relatively new generation gas-solid flow reactors used in various applications such as drying, catalytic polymerization, treatment of wastes, particle coating and chemical vapor deposition due to their advantages over cylindrical spouted beds. For complete characterization of conical spouted beds, determination of the local flow structure based on gas velocity and gas mixing is of paramount importance. There are limited studies on local gas behavior in conical spouted beds, especial...
Surface characteristics and in-vitro behavior of chemically treated bulk Ti6Al7Nb alloys ESEN, ZİYA; Ocal, Ezgi Butev (2017-01-15) The effect of various treatments on surface chemical composition and structure, and bioactivity of Ti6Al7Nb bulk alloys has been investigated. The alloys were treated employing aqueous solutions of NaOH and CaCl2 separately, and also by subsequent CaCl2 treatment after NaOH treatment (NaOH-CaCl2 treatment) which were followed by heat treatment. NaOH treatment was observed to be effective in enrichment of surface layer with Na. On the other hand, Na+ ions were mostly replaced by Ca2+ ions as a result of NaOH...
Seismic isolation of foundations by composite liners Kalpakçı, Volkan; Özkan, M. Yener; Department of Civil Engineering (2013) In this research, the dynamic behavior of a seismic isolation system composed of high strength geotextile placed over an ultra-high molecular weight polyethylene (UHMWPE) geomembrane (together called as composite liner) beneath the structure is investigated experimentally. The results of the shaking table experiments which were performed on model structures both under harmonic and modified earthquake motions with and without the seismic isolation (composite liner system), are presented in the thesis. The ma...
