Abstract: This paper explores the role that traceability and the use of predictive analytics could play in improving the durability and reusability of bamboo-based building materials. In an effort to better understand the problem being solved, a web-based monitoring platform has been developed across bamboo building projects in Jordan leveraging the use of Internet of Things (IoT) technology, machine learning modelling algorithms, and a web-based...

Abstract: Plant-extract inhibitors are attractive for mitigating marine and oil-and-gas corrosion while reducing toxicity and environmental persistence. Here, an aqueous Psidium guajava (guava) leaf extract was evaluated as a green inhibitor for mild steel in 5% NaCl at room temperature for 24 h, under both (i) conditions without H₂S and (ii) H₂S-souring simulated by in situ Na₂S/acetic acid. Inhibition performance was pre-screened by the weight-loss... More

Abstract: This article presents a study on the development of environmentally friendly materials. In the current context of environmental preservation, facing climate change and the search for material solutions, the development of ecological materials has become essential. Composites reinforced with natural fibers offer a sustainable alternative to synthetic materials. Among these fibers, palm fibers stand out for their low cost, lightness, and... More

Abstract: Concrete deterioration in aggressive environments poses significant challenges for the durability of reinforced concrete structures. The incorporation of supplementary cementitious materials offers a promising strategy to enhance performance while reducing cement consumption. This experimental study investigates the effects of metakaolin and waste ceramic tile powder as partial cement replacements on the compressive and flexural behavior of... More

Abstract: Throughout recorded history, masonry has played a significant role in the construction of structures across diverse cultures and geographic regions. In the last century, concrete masonry units (CMU) have effectively replaced traditional red brick in masonry in the US with the exception of some veneer purposes. CMU structures are significantly stronger than traditional masonry and have a wide variety of uses, with walls being the most common... More

Abstract: This study presents an experimental investigation on the structural performance of reinforced concrete (RC) gable beams strengthened with carbon fiber reinforced polymer (CFRP) sheets. A total of six RC gable beams were cast and tested under static loading applied at mid-span. One specimen served as a solid control beam, while two unstrengthened specimens incorporated eight circular or trapezoidal openings to reduce self-weight. The remaining... More

Abstract: This study explores the synergistic effects of welan gum-based anti-washout admixtures (AWAs) and slump-retaining polycarboxylate ether superplasticizers (SK-PCEs) in underwater concrete (UWC). It addresses the inherent challenge of simultaneously achieving sufficient viscosity to resist washout while maintaining adequate workability for extended placement. Three mortar series incorporating different water-to-binder (w/b) ratios and AWA/SK-PCE... More

Abstract: Openings made in reinforced concrete (RC) slabs can disturb force transfer and reduce stiffness, particularly when the slab has already been damaged. This paper reports the second-stage test of six RC slab specimens that had been loaded previously under concentrated column loading. After the first-stage tests, the damaged slabs were repaired with epoxy and strengthened with one externally bonded FRP N300 sheet layer on the bottom face. The FRP... More

Abstract: Aragonite-derived bio-calcium originates from food industry waste and has potential for partial replacement of ordinary Portland cement (OPC) in cementitious systems. The objective was to study the effect of partial replacement of OPC with cuttlebone powder (CBP) on hydration products and microstructure. The six mixture groups used CBP contents of 0%, 10%, 20%, 30%, 40%, and 50% to partially replace OPC by weight at a constant water-to-binder... More

Abstract: The swift advancement of modern construction has established cold-formed steel (CFS) as a prominent structural option owing to its high strength-to-weight ratio and lightweight properties. However, CFS in open sections such as channel and zee sections is heavily restricted by susceptibility to premature instabilities such as local, distortional, and lateral-torsional buckling. The study examines the structural performance, especially the... More

Abstract: The use of foundation systems on clayey soils poses serious challenges due to their low shear strength and high compressibility, making the need for appropriate sustainable foundation systems necessary. This study analyzed the structural capacity and the material effectiveness of reinforced concrete piled raft and pile cap foundation systems through full-scale field tests. Tests were carried out using reinforced concrete piles with a square... More

Abstract: The formulation of one-part geopolymer mortars for extrusion-based three-dimensional concrete printing (3DCP) requires a balance between fresh-state workability, controlled setting behaviour, and adequate mechanical strength. To address this need, this study established a sequential mixture-selection framework for ambient-cured, one-part fly ash–ground granulated blast-furnace slag (FA–GGBS) geopolymer mortar and evaluated its fresh-state...

Abstract: This article is devoted to a comparative evaluation of mortar compositions intended for the restoration of historic buildings and cultural heritage sites. Eleven plaster mortar compositions were considered, as well as a pure lime-sand mortar and a cement-sand mortar. Tamasli Natural Hydraulic Lime 5 (NHL5) was used as the hydraulic lime. The hydraulic modulus of the lime was M = 2.69. Cement grade CEM I 42.5N was used to prepare the cement-sand... More

Abstract: Using recycled materials as eco-friendly construction materials has been a growing trend in recent decades. In particular, obtaining discarded polymeric and asphaltic materials recovered from waste and reprocessing them into new products has decreased the demand for mining raw minerals, thereby minimizing negative environmental impacts. This study focuses on two materials that, when discarded, occupy large amounts of landfill space and... More

Abstract: The study area is in the western central part of Saudi Arabia. The present study aims to shed light on the field, megascopic and microscopic characterization of the different types of industrial and building raw materials of Al Barzah area. Geologically, the study area includes: i.e., gabbro, diorite, and rhyolites of the Kamile suite and Hashash Granites, which are overlained by the layered succession of the Samaran Group. In some areas,... More
