Behaviour of Geopolymer Mortars after Exposure to Elevated Temperatures

Kaya, Mehmet; Uysal, Mücteba; Yılmaz, Kemalettin; Cengiz Duran Atis (KAUNAS UNIV TECH, 2018)

In this study it was investigated the behavior of class F fly ash based geopolymer mortars subjected to elevated temperatures. Geopolimer composites were prepared with CEN-sand, water, fly ash as the binder, nSiO(2)Na(2)O ...
Effect of mineral admixtures on properties of self-compacting concrete

Uysal, Mücteba; Yılmaz, Kemalettin; Uysal, Mehmet (ELSEVIER SCI LTD, 2011)

In this study, the benefits of limestone powder (LP), basalt powder (BP) and marble powder (MP) as partial replacement of Portland cement are established. Furthermore, LP, BP and MP are used directly without attempting any ...
Effect of pre-setting pressure applied to mechanical behaviours of reactive powder concrete during setting phase

İpek, Metin; Yılmaz, Kemalettin; Sümer, Mensur; Sarıbıyık, Mehmet; İpek, Mediha (ELSEVIER SCI LTD, 2011)

In this study, mixing rates, fiber content and pre-setting pressure of reactive powder concrete (RPC) were examined. Mixing ratios were determined by different mixing techniques in literature using material characteristics ...
EVALUATION AND INVESTIGATION OF WASTE GLASS AGGREGATES AND POWDERS IN ARCHITECTURAL MORTARS

Heydar Dehghanpour; Yılmaz, Kemalettin (VORONEZH STATE TECHNICAL UNIV, 2019)

Conclusions. According to the results, the mortar with mixing ratios of 1.5 : 3 : 1 (cement : glass aggregate: glass powder) seems appropriate in terms of appearance, mechanical, impact and thermal properties. It is also ...
Evaluation of recycled nano carbon black and waste erosion wires in electrically conductive concretes

Heydar Dehghanpour; Heydar Dehghanpour; Yılmaz, Kemalettin; Yılmaz, Kemalettin; Yılmaz, Kemalettin; Yılmaz, Kemalettin; İpek, Metin (ELSEVIER SCI LTD, 2019)

Increasing number of studies have focused on the materials to impart electrical conductivity into concretes. Yet, economical concerns hinder the use of conductive materials in large-scales. This study investigates the ...
High-temperature behavior and mechanical characteristics of boron waste additive metakaolin based geopolymer composites reinforced with synthetic fibers

Abdullah Celik; Yılmaz, Kemalettin; Orhan Canpolat; Mukhallad M. Al-Mashhadani; Yurdakul Aygormez; Uysal, Mücteba (ELSEVIER SCI LTD, 2018)

This paper aims to examine high-temperature behavior and some mechanical and microstructural characteristics of boron waste additive metakaolin based geopolymer mortar composites reinforced with four various fiber types. ...
Improvement of the performance of alkali activated blast furnace slag mortars with very finely ground pumice

Yılmaz, Kemalettin (ELSEVIER SCI LTD, 2013)

This work investigates the strength and durability of alkali activated blast furnace slag mortars (AAS) with very finely ground pumice (P) at certain rates. BFS was used instead of cement at the rate of 60% and 80%. Sodium ...
MECHANICAL AND IMPACT BEHAVIOR ON RECYCLED STEEL FIBER REINFORCED CEMENTITIOUS MORTARS

Heydar Dehghanpour; Yılmaz, Kemalettin (VORONEZH STATE TECHNICAL UNIV, 2018)

Conclusions. According to the results, the specimens reinforced with RSFs showed improvement in all three compressive, flexural and impact behaviors, compared to unreinforced specimen. Depending on the amount of RSF, ...
Properties and behavior of self-compacting concrete produced with GBFS and FA additives subjected to high temperatures

Uysal, Mücteba; Yılmaz, Kemalettin; İpek, Metin; Uysal, Mehmet; İpek, Mediha (ELSEVIER SCI LTD, 2012)

This paper presents an experimental investigation on the performance of self-compacting concrete (SCC) subjected to high temperatures. For this purpose, Portland cement was replaced with fly ash (FA) and granulated blast ...
The effect of mineral admixtures on mechanical properties, chloride ion permeability and impermeability of self-compacting concrete
