Development of flaw tolerant fiber reinforced cementitious composites with calcined kaolin
(Elsevier Ltd, 2017)
Flaws naturally occur in the structure of the cementitious composites or concrete. When brittle composites (ceramics, concrete) are loaded up to their ultimate capacity, micro-cracks initiate and propagate from these flaws ...
Determination of drying kinetics and quality parameters of grape pomace dried with a heat pump dryer
(Elsevier Ltd, 2018)
Pomace of Hamburg Muscat was dried at temperature of drying air 45 °C and different air velocity (1.5, 2.0 and 2.5 m/s) in open-loop heat pump (HP) and laboratory-type closed-loop dryer (as a control). In the HP dryer, it ...
Effectiveness of microfine portland cement grouting on the strength and permeability of medium to fine sands
(Budapest University of Technology and Economics, 2015)
The purpose of this research was to investigate the grout properties of microfine Portland cement whose specific surface area was greater than those of the same kind products frequently cited in the relevant literature. ...
Performance of novel chemical grout in treating sands
(American Society of Civil Engineers (ASCE), 2017)
A new chemical grouting formed by sodium silicate-boric acid mixtures was introduced. Initially, suitable sodium silicate and boric acid contents in the grout mixtures were studied. Gel time, initial viscosity, and syneresis ...
UCS properties of superfine cement-grouted sand
(American Society of Civil Engineers (ASCE), 2016)
This research focused on the strength characteristics of superfine cement-grouted sand with various gradations and relative densities. At first, grout properties of superfine cement suspensions were studied. The sedimentation ...
Ultrafine Portland cement grouting performance with or without additives
(Springer Verlag, 2014)
The aim of this experimental study was to investigate the penetrability of ultrafine Portland cement suspensions with or without additives into sand specimens and the strength and permeability of grouted sand samples. It ...
Çimento esaslı lifli kompozitlerin dijital görüntü korelasyonu yöntemi ile çoklu çatlak davranışının incelenmesi
(Gazi Üniversitesi, 2019)
Dijital görüntü korelasyonu (DIC), matematik tabanlı temassız bir deformasyon ölçüm tekniğidir. Mühendislik özellikleri geliştirilmiş çimentolu kompozitler (ECC) geleneksel lifli kompozitlerden farklı olarak kararlı çoklu ...
Askorbik asitin MoS2 esaslı elektrotla elektrokimyasal tayini
(Ahmet Yesevi Üniversitesi, 2017)
Bu çalışmada, grafen, grafen oksit ve MoS iki boyutlu nanotabakalarına ayrılmak suretiyle 10 farklı kaplama süspansiyonu hazırlanmıştır. Hazırlanan kaplama süspansiyonlarıyla damlatarak-kaplama yöntemi kullanılarak camsı ...
A model suggestion for the determination of the traffic accident hotspots on the Turkish highway road network: a pilot study
(Universidade Federal do Parana, 2015)
Traffic accidents are very serious problems for human life and the environment. In road safety, it is crucial to identify the high risk locations to apply proper counter measures. This paper aims at introducing outcomes ...
Mechanical characterization of ruthenocuprates by nanoindentation technique
(Springer New York LLC, 2014)
The nanomechanical properties of RuSr 2 RECu 2O8 (RE = Eu, Gd and Ho) prepared by ammonium nitrate melt technique (ANMT) were investigated using nanoindentation technique. The indentation load–displacement curves of the ...
