Cement incontrovertibly, is the major and the most widely used binder in the structural concrete. However, the production of cement requires high energy and concedes great amounts of contaminants. From both economical and environmental point of view incorporation of wastes or by-products from various industries in the production of cementitious materials, is an increasing trend in concrete technology. This article investigates the use of ground granulated blast furnace slag, obtained by grinding the by-product of iron industry; fly ash, a waste product of thermal power plants, and zeolite, a natural mineralogical material having pozzolanic behavior, as cement replacement materials. The effects of ground granulated blast furnace slag, fly ash and zeolite replacement by cement on compressive strength of mortars were investigated. For this purpose a control specimen by using only cement as binder and 27 different mortar mixes with 10. 20 and 30% replaced with cement, by weight, were produced. Three 50x50x50 mm cubic specimens were cast for each mix. In order to set forth the discrepancies in different standards the mortar mixtures were prepared following three different criteria: constant water/binder ratio, constant flow and constant volume. The compressive strength of each mix was determined at 7th, 28th and 90th days. The results showed that all of the cement replacement materials exhibited significant contribution on compressive strength of mortar specimens. Therefore, utilization of waste products in cement materials caused not only technical but also economical and ecological advantages.

Strength assesment of Turkish cements
Kul Gül, Nazlı İpek; Yaman, İsmail Özgür; Akkaya, Ayşen; Department of Cement Engineering (2015)
Cement, a hydraulic binder material, is the most important of building materials. The compressive strength test method is used to determine the quality of cement. The cement manufacturers are obliged to carry the CE Marking in accordance with the EN 197 standards for cement production in Europe and Turkey and in accordance with the Building Materials Regulation (CPR). Within the scope of CE Marking, the product certification body performs sampling from the factory in specified periods. The samples obtained ...
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...
Seismic behavior of double walls with continuity reinforcement
Binici, Barış; Canbay, Erdem (null; 2015-07-21)
The conventional precast construction has deficiencies especially related to its connections between structural elements. Hence, its use in earthquake zones has been limited. However, the seismic performance of these systems can be improved by a semi-precast system, namely the double wall system. In this structural system, both precast and cast-in-situ concrete elements are utilized during the construction period, i.e. precast concrete shells are benefitted as a formwork to place cast-in-situ concrete. In t...
Hydration of alinite cement produced from soda waste sludge
Ucal, Gultekin Ozan; Mahyar, Mandi; Tokyay, Mustafa (2018-03-10)
Alinite cement is an alternative inorganic, low-energy binding material. This experimental study investigated hydration characteristics of alinite cement which was produced by using soda waste sludge as a raw material. Paste microstructures were studied by X-ray powder diffraction and scanning electron microscopy. Heat of hydration and compressive strength values were also determined. Formation of C-S-H gel and calcium chloroaluminate hydrates which resemble Friedel's salt was observed. Induction period of ...
Seismic behaviour of the old-type gravity load designed deteriorated RC buildings in Cyprus
Safkan, Ismail; Sensoy, Serhan; Ertuğrul, Zehra (2017-12-01)
Corrosion related deterioration of reinforced concrete buildings is often studied by the structural engineering community. The literature reveals the fact that modelling of deteriorated members requires a unique consideration due to brittle section behaviour. The late adaptation of seismic regulation rules and lack of decent quality construction material supply results a vulnerable building category in the island of Cyprus. This paper examines the vulnerable building category by combining concrete strength ...
