The majority of sawdust is produced by various lumber industries located all over the world. It has been established that using recycled materials to replace some of the fine aggregates is a viable solution. Most researchers focused on the durability aspect of wood sawdust concrete, while less information is available on its structural performance....

Considering their cost and strength benefits over traditional reinforced concrete, steel-concrete-steel (SCS) structural systems have become increasingly popular. The ultimate strength, ductility index, failure modes, cost, environment, and energy absorption capacities of SCS filled with sawdust concrete were explored in this study to better unders...

In structural and civil engineering, reinforced concrete structures are susceptible to inordinate loadings such as earthquake disasters, terrorist attacks and accidental impacts. This prompts an increasing desire to strengthen as well as enhance the fatigue performance and extend the ability of fatigue life of reinforced concrete structural compone...

This research is mainly studied the effect of treated waste crushed brick and steel slag on the shear behavior of reinforced concrete beams. For that purpose, eight concrete beams with 1000 mm length, 150 mm height, and 125 mm width, and the transverse reinforcement spaces are constantly equal. The obtained crushed brick from building demolition wa...

Laying of service pipes such as sewage pipes, electricity pipes, and sometimes water pipes ducts and others had presented some problems especially if it gathered in one place. One of the best solutions to minimize the problems and solve the piping and other services is using longitudinal and transverse opening in beams (BLTO), especially when high...

Reinforced concrete deep beams are structural elements that primarily pass-heavy gravity loads to their supports by shearing action. High shear strength is a significant feature of deep beams. This is due to the tied-arch internal a mechanism which transmits the load directly via concrete compressive struts to the supports. Various researchers and...

Although the ductility index of the reinforced concrete element has been the subject of many research objectives and critical analysis recently, scare consideration is carried out to measure the ductility of reinforced self-compacting concrete (SCC) enhanced with steel fiber. Hence, the current study aims to evaluate the ductility, in terms of ener...

Steel scrap is a waste product of steel plate manufacturing industry. A large quantity of steel scrap is produced by drilling every year. The disposal of those steel scraps is a major issue in Iraq and all over the world. The landfill is one of the methods for disposing the scraps albeit it produces soil pollution. What is worse is that in Iraq the...

The proper management of solid waste demands acting with it in a process that guarantees community health and environmental safety within an incorporated method that is multi-faceted, interlinked and components, and therefore it is important to apply appropriate means in terms of disposal of this waste to use it that makes it appropriate to be prev...

The study discusses the results of the experiment carried out about the effects of incorporation of waste ceramic tiles aggregate combined with waste glass powder on the performance of cementations mixtures. Crushed gravels in concrete mixes were replaced by ceramic tile (CT). Their ratios were 15%, 30%, 45%, and60%. On the other hand, glass powder...

This work used a model of integrated the fuzzy set theory and Decision-Making Trial and Evaluation Laboratory to evaluate the green practices that can affect the green supply chain implementation in battery industry. The integrated fuzzy MCDM model is used to assess the GSCM performance in company based on green terms: green purchasing, green manuf...

The present research was conducted to trace the influence of calcium carbonate by treating crumb rubber and exploiting oil palm fruit fibre (OPFF) incorporated mortars. The mechanical properties of treated crumb rubber and the addition of OPFF mortar being added at 0.5% OPFF and crumb rubber replacement of 0-30% by volume of aggregate were examined...

Plastic waste management has become a burden and a threat for countries and major cities as well as a danger to environmental safety. The current report covers the ability of the concrete sector to use and recycle plastic wastes. The demand for concrete and raw materials for construction engineering has become very high in recent years because of u...

Experimental work was carried out to study the effect of using steel slag (SS) and recycled concrete aggregate (RCA) as replacements for the natural aggregate in concrete. Waste materials, such as SS, which is a by-product generated during the production of steel and concrete rubble, which is produced by demolition activities, are dumped in landfil...
