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 work, Intralube E with 0.38 % C press-ready mix powders were pressed with 550 MPa pressure and sintered 25 min at 1120 °C. Samples were coated electrochemically with nano diamond (ND) reinforced nickel to study the effect of nano composite coating on c…

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 …

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 …

In this study, the effects nano-SiO2 and nano-Al2O3 on cement mortars were experimentally studied. The percentage of nano-powders were used as 1%, 3% and 5% into the material. Different types of analysis were used to nano-powder’s impact on the cement mortars.…

Use of superplasticing chemical admixtures in concrete production is widespread all over the world and has become almost inevitable. Super-plasticizers (SPA), extend the setting time of concrete by adsorbing onto cement particles and provide concrete to preser…

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…

Optimal reactive power flow and economic power dispatch is very important in power systems. Optimal reactive power flow provides minimum active power loss and economic power dispatch provides minimum active power generation cost in power systems. This study pr…

In this work, the effects of bis (2-methoxy-4-allylphenyl) oxalate (I) on levitation (Fz) and lateral forces (Fx) of bulk MgB2 superconductor has been investigated and reported for the first time. All samples were prepared from magnesium powder (Mg, 99.8 %),…

The high consumption of surfactants throughout the world (more than 15 million tons/year), together with their toxicity and negative effect on the self-purification capability of surface waters, make these synthetic organic compounds one of the main environmen…

Dünya toplam bor rezervi sıralamasında Türkiye % 72’lik pay ile ilk sıradadır. Bor elementinin; ilaç ve kozmetik sanayi, inşaat ve çimento yapımı, cam sanayi, kimya sanayi, ahşap malzemelerinde koruyucu, makine sanayi, nükleer sanayi, tarım sektörü ve otomobil…

Friction stir spot welding (FSSW) method is prone to automation. In this way, by integrating the robot and automation systems have been easily developed. Thanks to the method, the effective overlapping joints can be obtained a short processing time. In the stu…

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…

In this study, in an effort to develop polymer matrix composite materials, especially to be employed as workbench and kitchen bench usage, powdered waste porcelain was used as a filler to form satisfactory mechanical properties together with Salvadora persica …

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…

Yapıların depreme karşı güvenliğini artırmak için yerinde beton basınç dayanımının belirlenmesinin önemi gün gittikçe artmaktadır. Bunun için mevcut yapıların güvenliğinin artırılması büyük önem arzetmektedir. Bu çalışmada yerinde beton basınç dayanımının beli…

Beton teknolojisindeki gelişmeler, dayanım ve dayanıklılık açısından yüksek performanslı beton üretimine olanak sağlamaktadır. Betonun mekanik özellikleri büyük ölçüde malzeme bileşenleri, taze beton performansı ve bakım koşullarına bağlıdır. Normal beton, taz…

Aluminum based metal matrix composites are frequently used in automotive, aircraft, space, automotive, agricultural and building industries due to their easy shaping, good heat and electrical conductivity, low density, high strength and toughness. In these com…

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 …

Since the design of the first high rise building, the “Home Insurance Building” erected in Chicago in 1884-1885 only with 11 floors, new technologies encourage the designers to build taller and slender buildings penetrating through the sky. In the history, h…
