Paperback. Condizione: New. Print on Demand. This book presents an in-depth study of the various types of surface clays found throughout the state of Illinois, focusing on their potential use as bonding clays for synthetic molding sands. The author first discusses the geological context of these clays, explaining the different processes that have led to their formation and distribution. The book then presents the results of a series of tests conducted on samples of these clays, assessing their bonding properties and comparing them to those of commercial bonding clays and bentonites. The author also explores the possibility of improving the bonding properties of these clays through beneficiation techniques such as hydraulic classification. The book concludes with a discussion of the potential commercial applications of these clays and the implications of the author's findings for the use of surface clays in the foundry industry. The author's research provides valuable insights into the characteristics and potential uses of Illinois surface clays, making this book an important resource for geologists, materials scientists, and professionals in the foundry industry.

Paperback. Condizione: New. Print on Demand. This book presents a thorough exploration of Omega limestone resources across several counties in Illinois. It delves into the geology and characteristics of the limestone, discussing its occurrence, overburden, and suitability as a valuable resource for agricultural and construction purposes. The study provides an in-depth examination of the limestone's chemical composition, specifically its Calcium Carbonate Equivalent or neutralizing value, offering insights into its effectiveness in neutralizing soil acidity. Additionally, the book presents detailed findings from soil auger borings conducted in various areas, revealing the depth and thickness of limestone deposits. These findings are crucial for determining the feasibility of limestone quarrying operations and estimating the potential yield of usable stone. The significance of this book lies in its practical value for farmers, quarry operators, and anyone seeking to harness the benefits of Omega limestone for agricultural or construction projects.
