Abstract: The need for a transition to a low-carbon construction industry is met with the need for a nonprofit intermediate system of trust plus institutional mechanisms plus transparency technology. In answering its gaps in knowledge, this study explored whether trust, system of governance, or the use of blockchain technology for transparency impacts performance in the value chain related to SCM-low carbon SCM in Jordan. The methodologies used in... More

Abstract: The construction sector urgently needs methods to identify building materials that are both structurally reliable and environmentally efficient. This paper addresses the scientific issue of eco-efficiency assessment under deep uncertainty in life cycle, cost, and performance data for structural concretes. The research objective is to develop a robust decision-support framework that can rank conventional and low-carbon concretes when expert... More

Abstract: The construction sector is a major contributor to global carbon emissions and the extinction of resources owing to the heavy use of natural aggregates and production of construction and demolition waste (CDW). The paper examines the viability of using recycled aggregates in the form of CDW as substitutes (0, 10, 30 and 50) of natural coarse aggregates in M25 structural concrete. Experimental testing comprised workability, density, water... More

Abstract: The cement manufacturing process emits significant greenhouse gases and consumes substantial energy. The current situation demands alternative sustainable materials to cement in concrete production. On the other hand, rapid urbanization has led to the vertical expansion of modern structures, worsening daylight loss on lower floors, where artificial lighting is now essential. Innovative construction materials that enhance natural illumination are... More

Abstract: 3D Concrete Printing (3DCP) is an emerging technology with well-established benefits and the potential to dramatically change the construction industry. While research in material and process optimization is gaining traction, the architectural application of 3DCP remains relatively underdeveloped. Among many challenges, a lack of suitable computational modelling techniques is often identified as a major obstacle, resulting in simplistic design... More

Abstract: Natural fiber-reinforced composites have attracted considerable attention as environmentally sustainable substitutes for conventional synthetic materials. Nevertheless, determining an appropriate fiber loading remains a critical issue, since higher reinforcement contents may improve stiffness while adversely affecting ductility and overall mechanical behavior. In the present work, the tensile performance of epoxy composites reinforced with... More

Abstract: Steel box girders are known to be applied in several construction projects because of their structural efficiency characterized by a high strength-to-weight ratio, torsional rigidity, and effective structural design. Nonetheless, incorporation of web openings to gain easy utility access, inspection, and reduced girder self-weight will affect the internal stress pattern and possibly cause a great impact on its load resistance capacity when it is...

Abstract: The effect of ceramic waste powder (CWP), which is a byproduct of construction and demolition waste (CDW) on a local Wadi obtained sandy silty soil as a soil stabilizer is investigated. Laboratory tests were run at the 25% CWP by dry weight of soil, including Standard Proctor compaction (ASTM D698), sieve analysis (ASTM D6913), direct shear (ASTM D3080) and permeability tests. The results demonstrated that 10.3% increase in maximum dry density... More
