In response to the decreasing availability of high-grade kaolinitic clays, there is a growing shift toward using natural waste clays as supplementary cementitious materials. The performance of these waste clays is generally evaluated based on either strength or environmental impact, but the combination of both is rarely considered. This study undertakes a strength-normalized life cycle assessment to understand the interaction...

Concrete waste recycling is increasingly recognized as a strategy for reducing the environmental burdens associated with end-of-life construction materials, landfilling, and virgin material extraction. Within the transition to a circular economy, recycled concrete aggregate has gained growing attention as a secondary aggregate resource for concrete production. However, before recycled aggregate concrete (RAC) can be widely pro...

The disposal of construction and demolition waste (CDW) poses a critical global environmental challenge, driven by the low recyclability of concrete due to the limitations of recycled aggregates (RA). These aggregates suffer from the high porosity of attached mortar, resulting in elevated water absorption, reduced density, and diminished mechanical performance, restricting their application in structural concrete. This compreh...

Purpose Bricks and roof tiles are commonly employed in construction, posing environmental challenges due to their substantial use of natural resources. Efforts to mitigate these concerns include the integration of recycled materials. However, within the framework of life cycle assessment (LCA), it is imperative to ascertain that the incorporation of recycled materials enhances the sustainability of the product across its entir...

This study presents a transformative dynamic amplification factor for assessing the resilience of over-river bridges, informed by the real-world conditions of flood events. Through advanced finite element analysis, we unveil how the interplay between mass and velocity of floating objects significantly influences bridge pier responses, challenging conventional assessment methods. Our findings reveal potential inadequacies in cu...

The structural safety and serviceability during extreme weather, such as floods and storms, is critical. Due to global warming in the last decades, the increase in the intensity of natural disasters, i.e., flood loading and the durability of the road structures and infrastructures, is becoming critical. Bridges and structures lose their capacity because of ageing over time. On the other hand, the load intensity is another reas...
