    Best Practices in Geotechnical and Pavement Engineering—An Introduction
    (Springer Science and Business Media Deutschland GmbH, 2024) Kolathayar, S.; Vinod Chandra Menon, N.; Sreekeshava, K.S.; Shekhawat, P.; Bhargavi, C.
    In the times of mounting infrastructure demands driven by rapid population growth, the pivotal role of geotechnical investigation in assessing the suitability of construction sites, especially on soft, compressible ground, cannot be overstated. However, the necessity to adhere to packed construction schedules has increased the prevailing trend of rapid construction, often accompanied by significant ground settlements and lateral deformations, which necessitate complex solutions for stability. To transform these challenges into a dependable foundation for construction, various ground improvement techniques, encompassing both mechanical and chemical stabilization methods, must be applied. Importantly, these techniques must align with principles of sustainability, acknowledging the current climate change scenario. Furthermore, the pursuit of sustainable pavement construction, which holds on to the utilization of locally available materials, resilient enough to withstand diverse weather conditions, has risen to prominence. The adoption of stabilized pavement materials, typically integrated into base and sub-base courses, not only ensures longevity but also serves as a much needed measure to conserve increasingly scarce aggregates. This chapter provides glimpse into a comprehensive book volume, delving into the best practices in geotechnical and pavement engineering, comprising five distinct thematic clusters including soil–foundation interaction, sustainable ground improvement techniques, the dynamics of geosynthetics within soil, advanced geophysics, innovative rock mechanics practices, and recent breakthroughs in pavement construction. These insights collectively underscore the need for sustainable and resilient infrastructure development, serving as a promising guide for the future. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2024.

    Recent Advances in Building Materials and Technologies–An Introduction
    (Springer Science and Business Media Deutschland GmbH, 2024) Kolathayar, S.; Sreekeshava, K.S.; Vinod Chandra Menon, N.; Shekhawat, P.; Bhargavi, C.
    This volume underscores the critical influence of building materials on construction projects, emphasizing their role in progress, quality, and operational durability. The construction industry's explosive growth, aligning with economic development, is noted as a positive force for industrialization and modernization. Amidst climate change considerations, the imperative for sustainable and resilient building materials is highlighted. Alternative materials, whether fully or partially replacing aggregates or cement, emerge as vital for sustainable and resilient construction. These include diverse industrial wastes (e.g., plastics, construction by-products) and fibers/ashes (e.g., jute, steel, sugarcane bagasse). A notable innovation is the geopolymer, an alkali-activated binder offering superior durability and mechanical strength with lower energy consumption and CO2 emissions than traditional cement. In waste material utilization, studies explore plastic, waste tea, scrap ceramic tiles, and construction waste in concrete, addressing both sustainable waste management and high-performance structures. Ash applications consider wood ash, palm oil fuel ash, and agricultural waste ashes as sustainable alternatives to traditional cement. Geopolymer advancements encompass mechanical behavior, heat conditions, and novel applications like using iron ore tailings. Durability assessment explores nanotechnology to enhance concrete properties and reduce energy consumption. Fiber-reinforced materials and compressed stabilized earth blocks reinforced with coconut fiber aim for enhanced mechanical properties and reduced carbon emissions. The volume also touches on construction project investigations, addressing safety, progress tracking, and construction delay analysis techniques. In essence, this synthesis offers a panoramic view of recent advances in building materials and technologies, contributing to a holistic understanding of sustainable and resilient construction practices. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
