Characteristics of calcined natural zeolites for use in high-performance pozzolan blended cements
Uzal, Burak; Kucukyildirim, E (ELSEVIER SCI LTD, 2014)Two natural zeolites with different characteristics were calcined at various temperatures in order to improve the benefits provided by their use in blended cements as cement replacement material. Natural zeolites were ... -
Compatibility of Superplasticizers with Limestone-Metakaolin Blended Cementitious System
Zaribaf, Behnaz H.; Uzal, Burak; Kurtis, Kimberley (SPRINGER, 2015)This study investigates the performance of polycarboxylate ether (PCE), polymelamine sulfonate (PMS), sodium lignosulfonate and naphthalene formaldehyde condensate (PNS) superplasticizers (SPs) with ASTM C595 Type IL cement ... -
Effect of characteristics of natural zeolites on their geopolymerization
Ozen, Sevgi; Uzal, Burak (ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)The properties of clinoptilolite-based geopolymers are investigated with a focus on the parameters affecting the reactivity of clinoptilolite in a geopolymer binder. A complete characterization of raw materials was carried ... -
Effect of mineralogical composition of clinoptilolite-bearing tuffs on their performance as a natural pozzolan in cementitious systems
Ozen, Sevgi; Uzal, Burak (TECHNO-PRESSPO BOX 33, YUSEONG, DAEJEON 305-600, SOUTH KOREA, 2021)In this study, pozzolanic reactivity and strength activity of zeolitic tuffs containing similar amount of zeolitic phase (clinoptilolite) and different types and amounts of impurities were examined in order to understand ... -
Effects of dry particle coating with nano- and microparticles on early compressive strength of portland cement pastes
Yorulmaz, Hediye; Uzal, Burak; Özuzun, Sümeyye; İlkentapar, Serhan; Durak, Uğur; Karahan, Okan; Atiş, Cengiz Duran (Tulpar Academic Publisher, 2021)It is known that nano-and microparticles have been very popular in recent years since their advantages. However, due to the very small size of such materials, they have very high tendency to agglomeration particularly for ... -
Green building envelope designs in different climate and seismic zones: Multi-objective ANN-based genetic algorithm
Himmetoglu, Salih; Delice, Yilmaz; Aydogan, Emel Kizilkaya; Uzal, Burak (ELSEVIER, 2022)In recent years, the major component of green building designs adopted by governments in order to reduce CO2 emissions as well as energy consumption is the green building envelope. The green envelope has the most important ... -
Influence of nano SiO2 and nano CaCO3 particles on strength, workability, and microstructural properties of fly ash-based geopolymer
Durak, Ugur; Karahan, Okan; Uzal, Burak; Ilkentapar, Serhan; Atis, Cengiz Duran (ERNST & SOHN, ROTHERSTRASSE 21, BERLIN, DEUTSCHLAND 10245, GERMANY, 2020)The influence of nano SiO2(NS) and CaCO3(NC) particles on the properties of class F fly ash based geopolymer mortar activated with different sodium ion concentrations have been investigated. Mortar mixture proportions were ... -
A new parameter influencing the reaction kinetics and properties of fly ash based geopolymers: A pre-rest period before heat curing
Durak, Ugur; Ilkentapar, Serhan; Karahan, Okan; Atis, Cengiz Duran (ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)In this study, the influence of a pre-rest period before heat curing (as a new parameter), on the physical properties, flexural and compressive strength, and microstructure of geopolymer mortars and pastes produced with ... -
Practical charts to identify the predominant clay mineral based on oxide composition of clayey soils
Sivrikaya, Osman; Uzal, Burak; Ozturk, Yunus Emre (ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2017)This study proposes some useful practical charts representing the relationships between oxide composition and the type of predominant clay mineral present in clay soils. In order to produce the charts, the data set are ... -
Role of inclusion size distribution of titanium dioxide on the nitrogen oxides reduction capability and microstructural characteristics of cementitious systems
Bahsi, Emrah; Sahin, Oguzhan; Ilcan, Huseyin; Gunal, Muhammed Faruk; Yildirim, Gurkan; Sahmaran, Mustafa; Uzal, Burak (ELSEVIER SCI LTD, 2022)This paper explores the effect of the inclusion size of titanium dioxide (TiO2) particles on a variety of performance properties of cementitious systems via experimental studies. In addition to comprehensive microstructu ...
