Abstract: Researchers and engineers have been looking at novel approaches to develop cementitious materials with decreased environmental impact without sacrificing performance and durability in response to these difficulties. Calcium Sulfoaluminate-Belite cement (CSAB) is a value-added binder that has gained popularity for its unique qualities and benefits. The CSAB cement system is regarded as an innovative and promising sustainable construction material... More

Abstract: This research investigates the mixed proportions of cement, sand, water, superplasticizer, and waste materials, like recycled concrete, recycled rubber, recycled wood, tea-leaf residue, and recycled plastic, with their replacement levels clearly reported for reliability. Eight mixes were manufactured and tested at the Kuwait Institute for Scientific Research (KISR). The samples were then cured for 28 days, and compressive strength and thermal... More

Abstract: The shift towards sustainable and circular building systems has placed modular timber systems in the limelight as an alternative with lower carbon footprints. Nevertheless, the durability of the used material and the efficiency of the reuse cycle are factors that are now significantly impacted by digitalization. In the investigation described in this article, the influence of overall Supply Chain Digital Twin maturity and overall Supply Chain... More

Abstract: This study investigates the effect of steel wool fibre addition on the self-healing capability and Marshall performance of Asphalt Concrete Wearing Course (AC–WC). The concept of induction-activated self-healing is introduced to prolong pavement service life by restoring mechanical integrity after microcracking. Four fibre dosages (0%, 1%, 1.5%, and 2%) were evaluated through Marshall testing and controlled induction-healing cycles. The Marshall... More

Abstract: Coal bottom ash (CBA) is produced in large quantities by coal-fired power plants. It offers a viable opportunity for sustainable utilisation as a partial replacement, especially for fine aggregate in concrete. However, its porous morphology and surface characteristics complicate controlling water demand and optimising concrete performance. In this research, the synergistic effects of water–cement (WC) ratio (0.40, 0.45, and 0.50) with CBA... More

Abstract: The advent of low-carbon construction has made geopolymer concrete (GPC) a sustainable material for construction. However, the supply uncertainty of the raw materials needed for GPC production makes this a challenge. This research aims to develop and design an integrated digital twin-reinforcement learning framework for optimizing geopolymer concrete production processes. The problem statement concerns the uncertainty involved when producing... More

Abstract: The present review is a critical synthesis of the latest developments in the utilization of various wastes such as ceramic, marble, glass, rubber tire, paper industry, etc. and incorporates their mechanical, durability, microstructural, and sustainability performance among waste chemistry, hydration processes, interfacial transition zone modification, and long-term performance. The focus is laid on resistance to chloride ingress, sulphate and... More

Abstract: To reinforce and support long-span roofs, gable beams can be used. In order to reduce weight and to meet the requirements of modern construction in terms of passing electrical, sanitary and mechanical services, multiple openings must be created inside the gable beams. With those multiple openings in the gable beams, the structural performance of those beams and their architectural appearance will certainly improve. This research reviews the... More

Abstract: Production of cement is one of the major contributors to carbon dioxide emissions in the world, as such, there is motivation to come up with sustainable alternatives to cement production that would cut on the consumption of cement without affecting the structural performance. Out of all the municipal solid waste, cardboard waste is produced in huge amounts and has the potential to be reused in cementitious materials because it contains fibrous... More

Abstract: Geopolymers, characterized by their sustainable composition, are increasingly recognized as viable alternatives in construction materials. This paper examines the prospects of geopolymers within the sustainable blue economy, as a context emphasizing blue growth in smart, inclusive and above all sustainable development in the marine and maritime sectors. A synthesis of existing knowledge, emphasizing geopolymers’ potential contribution to... More

Abstract: The cement industry releases about 7 to 8% of the total anthropogenic CO2 in the world, which requires the creation of sustainable and performance-based alternatives to ordinary Portland Cement (OPC) concrete. The paper examines the synergistic behavior of fly ash (FA), rice husk ash (RHA), and fiber reinforcement in structural concrete. The concrete mix was made using the replacement content of FA-RHA cement (0, 10, 20, and 30%), and the dose... More
