Comparing the pozzolanic activity properties of obsidian to those of fly ash and blast furnace slag
(Elsevier Sci Ltd, 2018)
The use of pozzolan in cement provides economic advantages and improves the physico-mechanical properties of cement. Fly ash and blast furnace slag are widely used in cement as pozzolanic materials. in this study, obsidian ...
Numerical analysis of the receding contact problem of two bonded layers resting on an elastic half plane
(Techno-Press, 2019)
The present study deals with the numerical analysis of the symmetric contact problem of two bonded layers resting on an elastic half plane compressed with a rigid punch. in this context, Finite Element Method (FEM) based ...
Geotechnical studies and primary support design for a highway tunnel: a case study in Turkey
(Springer Heidelberg, 2019)
The main aim of this study is to appraise the geotechnical characteristic of the rock masses and to propose the proper support design for the Cankurtaran Tunnel project situated in NE Turkey. the exhaustive engineering ...
Spatially variable effects on seismic response of the cable-stayed bridges considering local soil site conditions
(Techno-Press, 2019)
In this study, stochastic responses of a cable-stayed bridge subjected to the spatially varying earthquake ground motion are investigated for variable local soil cases and wave velocities. Quincy Bay-view cable-stayed ...
Radiation shielding properties of mortars with minerals and ores additives
(Elsevier Sci Ltd, 2019)
Incorporation of mineral and ores as fine aggregate additives was investigated for its effect on the neutron and gamma-ray shielding properties of cement mortar. Five mortar mixtures have been prepared with different ...
Engineering geological appraisal and preliminary support design for the Salarha Tunnel, Northeast Turkey
(Springer Heidelberg, 2019)
The purpose of this study is to determine the engineering geological properties of the rock masses and to recommend a convenient support design for the Salarha Tunnel located in northeast Turkey. the detailed geotechnical ...
Assessment of rheological and sedimentation characteristics of fresh cemented tailings backfill slurry
(Taylor & Francis Ltd, 2020)
Unreasonable choice of solid content (SC) and cement-to-tailings ratio (c/t), including pipeline networking system, will lead to some pipeline problems, such as blockage, wear, and rupture. Hence, this study deals with the ...
Determination of the pozzolanic activities of trachyte and rhyolite and comparison of the test methods implemented
(Springer International Publishing Ag, 2020)
Natural pozzolanas should be evaluated in terms of sustainability as well as their contribution to concrete durability. Therefore, the use of such materials in the production of cement as well as concrete industry has been ...
Finite element modeling of contact between an elastic layer and two elastic quarter planes
(Techno-Press, 2020)
In this study, a two dimensional model of receding contact problem has been analyzed using finite element method (FEM) based software ANSYS and ABAQUS. For this aim finite element modeling of elastic layer and two homogeneous, ...
Examination of analytical and finite element solutions regarding contact of a functionally graded layer
(Techno-Press, 2020)
In this study, the continuous and discontinuous contact problems of functionally graded (FG) layer resting on a rigid foundation were considered. the top of the FG layer was loaded by a distributed load. It was assumed ...
