Assessing the Effects of Mechanical Preventive Measures on Alkali-Silica Reaction Expansion with Accelerated Mortar Bar Test

Musaoglu, Orhan
Sarıtaş, Afşin
This paper presents a modification to the apparatus of the mortar bar test of ASTM C490 in order to assess and compare the influence of mechanical preventive measures in reducing alkali-silica reaction (ASR) expansion in concrete with respect to the traditional measures. For this purpose, reinforced mortar specimens with or without pre-stressing force applied were examined and the effects of the reinforcement ratio and pre-stressing force on ASR-induced expansion and cracking were studied through the accelerated mortar bar test method of ASTM C1260. The mechanical preventive measure was also compared with a traditional preventive measure by using fly ash. The results show that reinforcement and pre-stressing force play a role in limiting expansion and cracking due to ASR and that the developed test apparatus in this study can be used for measurements.


Impact essential work of fracture toughness of ABS/polyamide-6 blends compatibilized with olefin based copolymers
Ozkoc, Guralp; Bayram, Göknur; Bayramli, Erdal (Springer Science and Business Media LLC, 2008-04-01)
The impact fracture toughness of acrylonitrile-styrene-butadiene/polyamide-6 (ABS/PA6) blends compatibilized with 5% by weight carbon monoxide modified ethylene-n butyl acrylate-maleic anhydride (EnBACO-MAH) or ethylene-methyl acrylate-glycidyl methacrylate (EMA-GMA) copolymers were examined as a function of blend ratio by standard Charpy tests, Essential Work of Fracture (EWF) Methodology and fracture surface morphologies. The samples were first processed in twin-screw extruder and they were subsequently i...
Prediction of forming limit curve at fracture for sheet metal using new ductile fracture criterion
Dizaji, Shahram Abbasnejad; Darendeliler, Haluk; KAFTANOĞLU, BİLGİN (Elsevier BV, 2018-05-01)
The application of ductile fracture criteria (DFCs) in numerical analysis of sheet metal forming processes can lead to the accurate determination of the fracture initiation. In this study, a new uncoupled ductile fracture criterion (DFC) has been developed which considers the effects of material parameters on the forming limit curves (FLCs) and can be easily implemented in the finite element codes. Two different constitutive models have been employed with the new DFC in order to evaluate the results obtaine...
Interactions at fiber/matrix interface in short fiber reinforced amorphous thermoplastic composites modified with micro- and nano-fillers
Isitman, Nihat Ali; Aykol, Muratahan; Kaynak, Cevdet (Springer Science and Business Media LLC, 2012-01-01)
This study aims at systematically extracting fiber/matrix interfacial strength in short-glass fiber-reinforced polymer composites using an experimental micromechanics approach which employs mechanical properties and residual fiber length distributions to derive the apparent interfacial shear strength. We started from neat high-impact polystyrene matrix short-glass fiber-reinforced composites (HIPS/GF) with varying fiber loading and proceeded toward HIPS/GF hybrid composites containing micro- and nano-filler...
Comparison of magnetic Barkhausen noise and ultrasonic velocity measurements for microstructure evaluation of SAE 1040 and SAE 4140 steels
Gür, Cemil Hakan; Çam, İbrahim (Elsevier BV, 2007-05-01)
The aim of this study is to compare the performance of magnetic Barkhausen noise and ultrasonic methods for the evaluation of the microstructure of commercial steels. Following the austenitization of the specimens made of SAE 1040 and SAE 4140, various heat treatments were carried out to obtain microstructures consisting of martensite, tempered martensite, fine pearlite-ferrite, and coarse pearlite-ferrite. The microstructures were initially characterized by SEM investigation and hardness measurements. The ...
The role of amorphous precursor in phase selection hierarchy in marginal metallic glasses
YILDIRIM, CİHAN; KUTSAL, M.; OTT, R. T.; BESSER, M. F.; KRAMER, M. J.; Kalay, Yunus Eren (Elsevier BV, 2016-12-15)
The solid state amorphous structure and devitrification products of Al90Tb10 alloys produced by Cu block meltspinning and magnetron sputtering were investigated by a combined study of differential scanning calorimetry, in-situ X-ray diffraction and conventional transmission electron microscopy. The as-prepared specimens were found to be fully amorphous according to the electron and X-ray diffraction. The thermal analysis and in-situ XRD analyses of the amorphous samples having the same chemistry but differe...
