Effects of the type and amount of fly ash substitution on the heat of hydration of portland cement-fly ash pastes were investigated. Three Turkish fly ashes were used. One of them was a high-calcium and the other two were low-calcium fly ashes. The specimens contained 0, 10, 20, and 40% fly ash by weight of portland cement. The tests were carried out as described in ASTM C 186 however one separate set of specimens were first subjected to an early external temperature of 67±2°C for six hours followed by the standard temperature until time of test. The results revealed that the low-calcium fly ashes, regardless of their type, reduce the heat evolution when used for partial cement replacement. The high-calcium fly ash, on the other hand, does not produce significant changes in the heat of hydration.

Effect of material characteristics on the properties of blended cements containing high volumes of natural pozzolans Turanlı, Lutfullah; Uzal, B; Bektas, F (Elsevier BV, 2004-12-01) The effect of three different natural pozzolans from Turkish deposits on the properties of blended cements produced by intergrinding cement clinker with a high volume of natural pozzolan (55 wt.% of the cementitious material) was investigated. The particle size distribution of blended cements, setting time, heat of hydration, and compressive strength of blended cement mortars were determined. Experimental results showed that the hardness of the pozzolanic material strongly influenced the particle size distr...
Effects of potassium ferrocyanide used for desalination on lime composite performances in different curing regimes Ergenc, D.; Feijoo, J.; Fort, Rafael; de Buergo, Monica Alvarez (Elsevier BV, 2020-10-01) Negative effects of salt weathering on porous building materials will increase because of the global climate breakdown. The addition of crystallization modifiers as desalination technique has attracted considerable scholarly attention. This study builds on this body of knowledge by investigating the effects of potassium ferrocyanide addition on air-lime mortar under different environmental conditions. Three experimental setups were selected with different curing regimes: i) molding, ii) between sandstones a...
Effect of heating rate on thermal properties and kinetics of raw and cleaned coal samples Özbas, Kazim Esber; Hicyilmaz, Cahit; Kök, Mustafa Verşan (Informa UK Limited, 2003-01-01) In this article, thermogravimetry (TG/DTG) was used to determine the effect of heating rate on the thermal properties and kinetics of raw and cleaned coal samples from Soma, Tuncbilek, and Afsin Elbistan regions. TG/DTG experiments were carried out at 4 different heating rates (5, 10, 15, and 20degreesC/min). Generally, for all of the samples higher peak and burnout temperatures were measured with an increasing heating rate. Kinetic parameters of the samples were determined using an Arrhenius-type kinetic m...
EFFECT OF TEMPERATURE, PH AND DO CONCENTRATION ON FILTERABILITY AND COMPRESSIBILITY OF ACTIVATED-SLUDGE SURUCU, G; Sanin, Faika Dilek (Elsevier BV, 1989-11-01) This study investigates the effect of aeration basin temperature, pH and dissolved oxygen (DO) concentration on filterability and compressibility characteristics of activated sludge. Laboratory-scale semi-continuous reactors, fed with synthetic wastewater were used. Effects of temperatures of 15, 20, 25, 30, 35°C; pH values of 5.7, 7.2, 8.2, 9.0 and DO concentrations of 0.5, 1.0, 1.5, 2.0, 5.0 ml/l were studied by keeping all the other parameters constant in each case. Results indicated that as the operatin...
Effects of granulated blast furnace slag trass and limestone fineness on the properties of blended cements Delibaş, Tuğhan; Yaman, İsmail Özgür; Hoşten, Çetin; Department of Cement Engineering (2012) The aim of this research was to determine the effects of the fineness of different mineral additives on loss on ignition, heat of hydration, physical, mechanical and chemical properties of blended cements. For that purpose, portland cement clinker was replaced with granulated blast furnace slag (GBFS), natural pozzolan (NP) and limestone (L) at 6%, 20% and 35% replacement levels. Blended cements containing GBFS and NP were ground to a fineness of 3000, 5000 and 6000 cm2/g. Cements containing L were ground t...
