Motivated by the tremendous trend toward green environment and to reduce the effect of scrap tires on the environment and human health, this research is an attempt to find a practical and environmentally sound solution of the problem of scrap tires by developing a light weight with low thermal conductivity composite construction materials using was...

The disposal of scrap tires is a challenging task and hence an innovative solution to meet these challenges is needed. Extensive work has been done on the utilization of waste tires in a variety of applications in asphalt pavements and concrete. However, previous investigations focus only on the mechanical properties of the rubberized materials, bu...

Title:Use of Crumb Rubber to Improve Thermal Efficiency of Construction Materials Abstract: Motivated by the tremendous trend toward green environment and to reduce the effect of scrap tires on the environment, this research is an attempt to find a practical and environmentally sound solution of the problem of scrap tires. A few literatures are ava...

Residual and end-life products are a major hazard on the environment. Many researchers have considered waste as partial replacement of some construction materials to reduce their environmental and ecological problems. This kind of practices can be an important option for the protection of the environment. Wood shavings and saw dust are byproduct of...

يعتبر استهلاك الاسمنت في أي مجتمع من أهم المؤشرات الاقتصادية الدالة على مستوى تطور الدخل الوطني وبزيادة مستوى التطور والنمو العمراني يزداد استهلاك الاسمنت. الإسمنت المستخدم لأغراض البناء هو عبارة عن مادة رابطة ناعمة تمتلك خواص تماسكيه وتلاصقيه وهذه الخواص تجعله قادرا بوجود الماء على ربط قطع الركام مع بعضها البعض وتحوله إلى وحدة كاملة متراصة وصلبة....

Using recycled concrete aggregate is an important step toward sustainability and preserving natural resources in the present and the future. Concrete is the most used construction material, which diminishes the natural resources related to its production, such as cement and aggregate (fine or coarse). In some instances, these materials are hard to...

Concrete is the most commonly used structural material in Libya, which is associated with the depletion of the materials involved in its production, especially the fine and coarse aggregate that make up around one-third of the substance. Since Libya is so large, there are different fine aggregate sources (sand), such as desert and coastal areas. Ad...

This paper presents experimental results on the influence of the spiral anchor system on the flexural behavior of concrete beams reinforced with glass fiber-reinforced plastic (GFRP) bars. The experimental program consisted of eight beams with the spiral anchor system and two control fiber-reinforced concrete beams without any spiral anchor system....

Despite the persistent attempts on a global level to adopt sustainability in every aspect of city planning, the complex nature of city components and the presence of many factors and variables that affect the growth and development of cities make the adoption of a specific trend not an easy matter. It may be more appropriate to identify some import...

The research aims to investigate the viability of employing polyester grout as a bonding agent for the splicing of reinforcement bars. 0.43 and 1 binder-to-filler ratio were examined. The process of splicing reinforcement bars under tension using a polyester grouted splice connector is elucidated. Through direct tension tests, the optimal mix desig...

The aim of this research is to propose a system for collecting and analyzing casual labor data in Libya, leveraging distributed systems and the Weka visualization tool. The current labor market in Libya relies heavily on casual labor, which poses challenges in terms of data collection and analysis due to its decentralized nature. The proposed syste...

High-strength grout is specified to increase the bond between grout and bar in grouted connections and to ensure that the forces in the bars can be transferred to the surrounding material accordingly. Although polymer grout is fast setting and rapid in strength development, the use of polymer mortar in grouted connections is still limited because o...

The use of rubberized concrete has become increasingly popular as a means of disposing of waste materials, such as used and end-of-life tires, while also providing an effective solution for construction applications. The strength and durability of rubberized concrete can be negatively affected by temperature fluctuations, but little is known about...

Most metropolitan areas in the world are facing major solid-waste-disposal problems. The solid-waste problem is considered one of the major environmental problems that countries and environmental organizations are paying increasing attention to at present, not only due to its negative effects on public health and the environment, but also due to th...

Intersections are one of the most crucial parts of urban transportation systems since they actively contribute to developing strategies to reduce traffic congestion. Congestion is one of the major issues that intersections face as a result of the growth in traffic, which cause lower service levels and longer waiting time. The main goal of this stud...

تعد الخرسانة من أكثر المواد الإنشائية شيوعا واستخداما وهذا يترافق مع استهلاك المواد الأولية المكونة لها بشكل كبير جداً. وحيث إن هذه المواد غير قابلة للتجدد ومصادرها محدودة في الطبيعة، دعت الحاجة الى إيجاد بدائل لها ولعل من أهمها هو استخدام المخلفات الصلبة كبديل جزئي او كلي للركام الناعم، الخشن او الاسمنت. من هذه البدائل المقترحة هو استخدام فتات الم...

Utilizing solid wastes and industrial by-products as a partial replacement for raw materials has become an acceptable practice among researchers and scientists in the civil engineering field. Sawdust and wood shavings are not an exception; they are being used in concrete as a partial or total replacement for some of its constituents. The main goal...

The aim of this research is to study the chemical, physical and mechanical properties of Portland cement (42.5N) of class I for ten types of cement, including local and imported, based on the American specifications ASTM), where chemical tests were carried out in the engineering laboratories of Al-Fateeh Cement Factory to obtain proactive results f...

Testing the confidence level of observation and correctly estimate the accurate observation. فى الكثير من الأعمال المساحية يقدم الوسط الحسابى على أنه القيمة المضبوطة القيمة الاكثر احتمالية للأرصاد التى تم قياسها ولكن هذا لا يعطى انطباعاً كاملاً عن مدى دقة هذه القياسات. بمعنى آخر هو لا يعطى صورة واضحة عن مدى تشتت الارصاد بعضها عن بعض للكمية الواحدة...

The aim of the study is to summarize the work done on Rubberized Concrete.
