"Geological Coarse Aggregates and Concrete" by Vishalakshi K P is an authoritative and comprehensive reference book that delves into the intricate relationship between geological formations, coarse aggregates, and concrete in the realm of construction materials. This meticulously researched work explores the vast spectrum of rocks and minerals, including sedimentary, igneous, and metamorphic varieties, and their crucial role in shaping the quality and performance of concrete.The book takes an in-depth look at various coarse aggregates used in construction, such as gravel, sand, limestone, granite, basalt, shale, quartz, and dolomite. It meticulously examines the properties of aggregates, including particle size, shape, texture, angularity, flakiness, elongation, specific gravity, absorption, porosity, and gradation. The author sheds light on essential testing techniques like sieve analysis, moisture content determination, and the assessment of aggregate strength, durability, workability, and other mechanical properties. Readers will gain valuable insights into the complex interplay between aggregates and concrete performance, including slump, compressive strength, flexural strength, tensile strength, abrasion resistance, freeze-thaw resistance, and the prevention of alkali-aggregate reactions. The book also explores the chemical properties, mineral composition, and petrographic analysis of aggregates, offering a comprehensive understanding of their characteristics and behavior. Moreover, "Geological Coarse Aggregates and Concrete" delves into aggregate production processes, quarrying, extraction, processing, and transportation, addressing sustainability concerns and environmental impacts associated with these operations. By integrating theoretical knowledge with practical applications, this book serves as an invaluable resource for researchers, engineers, and students in the field of civil engineering and construction. It offers a profound understanding of the intricate relationship between geological aggregates and their influence on the performance and durability of concrete structures.
