High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste

Polymer International, EarlyView.
Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments

Critical depth of normal cracks in reinforced concrete beams of rectangular cross-section

Journal of Civil Engineering and Management, 2013
The evaluation of stress state of longitudinal tensile reinforcement is highly important while examining the technical state of under-reinforced concrete structures. The appearance of yield stress in tensile reinforcement could be treated as the start of

Achieving Sustainable Development Goals Through Social Life Cycle Assessment: A Case Study of Portuguese Forest Wood Supply Chains

Sustainable Development, EarlyView.
ABSTRACT Social considerations are often overlooked in efforts to achieve sustainable development, despite being critical for building equitable and resilient global value chains. This study addresses this gap by applying a social life cycle assessment to three key Portuguese forest wood supply chains—uncoated woodfree paper, natural cork stoppers, and

Investigating the Environmental Impact of Additive Construction: A Systematic Analysis of the Life Cycle Assessment Studies

Sustainable Development, EarlyView.
ABSTRACT Additive Manufacturing (AM) has been identified as a potential catalyst for a paradigm shift within the construction industry, due to its capacity to enhance sustainability, reduce waste, and augment design flexibility. This study presents a systematic literature review (SLR) that explores the application of Life Cycle Assessment (LCA) in ...

Reinforced masonry shear walls

Bulletin of the New Zealand Society for Earthquake Engineering, 1982
Nine 2.4 m high by 1.6 m long reinforced masonry walls (140 mm) were cycled under reverse curvature loading. The walls were designed to investigate the effect of vertical preload and the effectiveness of repair by epoxy grout injection together with certain matters raised by the Draft Code for Design of Reinforced Masonry, in particular effect of ...

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...
