Evaluation of rock engineering properties is a significant phenomenon for mining, civil and geotechnical engineering disciplines. Uniaxial compressive strength is one of the most important engineering parameters and it is used to characterize rocks from the …

In this study, the development of the compressive strength obtained by heat-activation of the mortar produced with Fclass fly ash and sodium meta-silicate was investigated. In the study, mortar samples were produced using F class fly ash, standard Rilem sand a…

Complexity in the behavior of asphalt binders are further escalated with geopolymer (fly ash and the alkali liquid) modification thus, making it difficult to predict the performance of the binder accurately. This study employs artificial neural network model…

Plasticity index is one of the most important parameters affecting the behavior of fine-grained soils under monotonic and dynamic loads. Besides, various correlations between plasticity index and strength properties of fine grained soils can be obtained depend…

Titanium and its alloys are increasingly used in aerospace, automotive and biomedical industries because of their high strength, excellent corrosion, wear resistance and a wide range of mechanical properties. Materials with superior properties are needed in …

Nowadays, as the population increase, various construction projects are made on soils which engineering properties are not suitable. Many stabilization methods are used in order to prevent deformations and loss of bearing capacity on such soils. However, most …

Ceramic materials are characterized by outstanding hardness, extreme compressive strength and elastic modulus, wear resistance, thermal shock resistance, chemical stability and high temperature properties. Therefore they have potential materials to be use at i…

Rubble of destroyed buildings in Turkey is a growing environmental problem, in Ankara only, there are 12 landfills to collect and store them. Adobe is a world common building material; many studies inferred its environmental qualities. This study examines th…

The concrete, which is an important building material, has a wide range of uses through its economic advantages and many other advantages. Economics, easy obtainable, long life, easy curing and workability are some of the advantages. Concrete is the most used …

In this study, fiber fineness (µm), fiber strength (cN) and elongation (%) values of white and pigmented wool samples taken from female Merino sheeps between the ages of 0-2 years were compared. The results showed that both the fiber strength (cN) and elonga…

Increasing number of motor vehicles together with economic development brings serious air pollution problems. Especially, Particle Matter emissions from Internal Combustion Engines are difficult to control and highly dangerous for human health. Both Europa and…

One of the materials that are increasingly used today in various engineering applications is boron steels. Though boron steels draw attentions with their superior wear characteristics, studies on the tribological properties of these materials is quite limited …

In this study, hybrid composite structures were manufactured by vacuum assisted resin transfer molding method using three different woven fabrics (jute, E-glass and carbon) as the reinforcing material and polyester resin as the matrix material. All composite…

Lower limb exoskeletons are wearable robotic devices which either augment human power or facilitate a walking ability for those who lost it by injury or aging. They have been getting more and more attention in the scientific community thanks to its increasin…

In the last century, there has been an ever-increasing demand for novel materials namely known as composites. Biological fibers are reinforcement materials of composite structures owing to their economic and ecological advantages. Among these fibers, plant f…

Titanium and titanium alloys are suitable for a variety of applications, with their low density, high strength and high corrosion resistance. Despite strong mechanical and corrosive qualities, titanium use is restricted by its weak friction and wear characteri…

Many well-known material structures, such as metals, ceramics or polymers, cannot meet all the technological demands. For this reason, there is ongoing research into new materials with advanced features. A composite material is consisting of at least two phase…

As widely known, construction on soft soils is generally problematic since the engineering properties of soft soils generally cannot meet the conditions required. Settlement, bearing capacity and seismic performance of the overlying structures is always questi…

Additive manufacturing which is developed in the last half century is promising manufacturing technology. It uses layer-wise production method for obtaining finished product. In recent years, thousand researches were made but there was still gaps about impac…

Elastomer materials can be jointed using various connection types with metallic parts. Removable connections (with screws, nuts, etc.), adhesive and vulcanization methods are some of them. In this work, it is investigated that how joint between one type of e…
