Investigation of Relationship between Aggregate Shape Parameters and Concrete Strength Using Imaging Technigues



Investigation of variations in performance properties of asphalt concrete using image-based finite element model
Karakaya, Yalçın; Güler, Murat; Department of Civil Engineering (2022-7-20)
The objective of this study is to evaluate variations in performance properties of asphalt concrete using a two-dimensional image-based finite element model. Two different asphalt mixtures are used in both laboratory tests and in FEM analyses representing different conditions. A flatbed scanner is then used to capture cross-sectional images of the samples and various image processing techniques are applied to prepare the images for FEM. A unique image vectorization method has been developed to transform cro...
Investigation of the Macro Pore Geometry of Yellow Travertines Using the Shape Parameter Approach
Akin, Mutluhan; Ozsan, Aydin; Akin, Muge (GeoScienceWorld, 2009-08-01)
Porosity is one of the most important physical properties of rocks. Strength and deformation parameters as well as the effect and degree of weathering are also related to porosity. Rocks with high porosity are more vulnerable to weathering than are non-porous rocks. Consequently, identification of pore size and shape may assist the evaluation of strength characteristics and resistance to weathering. One approach used for the determination of macro pore geometry is the stereology method. The main principle o...
Investigation of relationship between aggregate shape parameters and concrete strength using imaging techniques
Özen, Murat; Güler, Murat; Department of Civil Engineering (2007)
In this study, relationships between aggregate shape parameters and compressive strength of concrete were investigated using digital image processing and analysis methods. The study was conducted based on three mix design parameters, gradation type, aggregate type and maximum aggregate size, at two levels. A total of 40 cubic concrete specimens were prepared at a constant water-cement ratio. After the compressive strength tests were performed, each specimen was cut into 4 equal pieces in order to obtain the...
Investigation of the effect of shearing rate on residual strength of high plastic clay
Akis, Ebru; Mekael, Ahmad; Yılmaz, Mustafa Tolga (Springer Science and Business Media LLC, 2020-01-09)
The residual shear strength on failure plane is a crucial parameter to be estimated for analysis of an active landslide. This strength must be determined precisely to build a reliable theoretical model for calculations. The multi-reversal direct-shear test is a practical method to determine this shear strength in laboratory due to wider availability of apparatus. The shearing rate is among the factors that significantly affect the precision of test results for clay specimens. However, limits for this rate a...
Investigation of the variations in microstructure and mechanical properties of dual-matrix ductile iron by Magnetic Barkhausen Noise analysis
Gür, Cemil Hakan; Erdogan, Mehmet (Informa UK Limited, 2008-01-01)
The variations in the microstructure and tensile properties of dual-matrix ductile irons have been investigated non-destructively by Magnetic Barkhausen Noise (MBN) method. Specimens have been intercritically austenitised at 795 degrees C and 815 degrees C for 20 minutes, and then oil-quenched to obtain different martensite volume fractions. Two specimens, namely as-cast and oil-quenched from 900 degrees C, were prepared for comparison purpose. To investigate the effect of tempering, some specimens were tem...
