Abstract

Nanomaterials hold immense potential for transforming the field of civil engineering, offering enhanced performance and durability to infrastructure materials. However, their successful implementation faces several challenges and limitations that must be addressed. This abstract highlights the critical challenges associated with nanomaterials in civil engineering, including high production costs, scaling up production, health and safety risks, long-term performance and stability, standardisation and regulation, integration with existing construction practices, lack of comprehensive data and knowledge, and the need for multidisciplinary collaboration. Overcoming these challenges requires optimised manufacturing techniques, safety measures, extensive research, standardised protocols, and cooperation among researchers, engineers, manufacturers, regulators, and policymakers. Addressing these issues will pave the way for the safe and effective utilisation of nanomaterials in civil engineering, unlocking their potential to create sustainable, resilient, and innovative infrastructure systems.

Abstract

This study focuses on the challenges and prospects of engineering procurement in Nigeria. The research examines the existing literature on engineering procurement practices, identifies gaps in knowledge, and explores potential areas for improvement. Through a comprehensive review, key findings emerge, highlighting limited research specific to engineering procurement in Nigeria and a lack of empirical studies on project performance and outcomes. Moreover, the literature review reveals a need for more research on engineering procurement projects' socio-economic and environmental impacts. The implications of these findings underscore the need for targeted research, enhanced data collection, and monitoring mechanisms to evaluate project performance accurately. Additionally, the study emphasises the importance of considering the broader socio-economic and environmental implications for sustainable development. Overall, this study serves as a foundation for advancing the understanding of engineering procurement in Nigeria and offers insights for policy-makers, researchers, and practitioners in the field.

Abstract

The integration of nanotechnology into the construction industry, specifically in developing asphalt and concrete pavement materials, holds great promise for enhancing infrastructure performance and durability. Nanomaterials, characterised by their nanoscale dimensions, typically less than 100 nanometers, are increasingly employed in pavement construction. This abstract provides an overview of various nanomaterials and their potential impact on road construction. Nanomaterials like nano-silica, nano clay, carbon nanotubes, nanocarbon black, nanofibers, nano titanium dioxide, nano alumina, and nano zinc oxide are explored in this context. These materials offer unique properties due to their small size and high surface area. For instance, nano silica has demonstrated its ability to enhance stiffness, strength, longevity, and resistance to rutting and cracking in asphalt pavement. Nanoclay reinforces mechanical and thermal properties in asphalt and concrete, improving overall performance. Carbon nanotubes and graphene show promise in concrete pavement by enhancing mechanical properties and reducing cracking. Furthermore, nanocoatings are being explored for pavement surfaces, offering benefits such as improved slip resistance, reduced noise, increased durability, and pollution resistance. Despite the potential advantages, challenges exist, including the need for standardised testing and characterisation procedures and the initial cost of incorporating nanoparticles into pavement materials. Ongoing research and development efforts are focused on addressing challenges and making these innovations more practical and cost-effective for widespread implementation. Nanomaterials have emerged as a viable solution to improve road construction, offering benefits for infrastructure performance while minimising environmental impact.

Abstract

The construction industry, a dynamic realm of progress and responsibility, grapples with the imperative to minimize waste and enhance sustainability. This exploration unfolds various strategies for effective waste minimization, delving into source reduction techniques, lean construction principles, prefabrication and modular construction, design for deconstruction, and just-in-time delivery. Source reduction, commencing at the construction process's inception, emphasizes material efficiency, inventory management, and process optimization. Lean construction principles draw inspiration from manufacturing methodologies, spotlighting just-in-time production, continuous improvement, and value stream mapping to optimize processes and eliminate waste. Prefabrication and modular construction techniques, with their focus on precision, transport efficiency, and design flexibility, promise faster construction, reduced waste, and heightened quality control. Design for deconstruction advocates for structures crafted with an end-of-life strategy, emphasizing material selection, component standardization, and minimizing adhesives. Just-in-time delivery orchestrates the timely arrival of materials, minimizing waste, handling, and environmental impact associated with excess inventory. These strategies collectively paint a narrative of efficiency, sustainability, and responsibility, urging the construction industry to shape a future where each structure is a testament to mindful environmental stewardship.
