Paperback. Condizione: New. Print on Demand. This book provides a guide to proportioning concrete mixtures for specific compressive strengths, ranging from 1,500 to 4,000 pounds per square inch. The author has conducted extensive research on the relationship between the water-cement ratio and the strength of concrete. Their findings have led to the development of a set of tables that can be used to determine the proportions of cement, aggregate, and water needed to produce concrete of a desired strength. These tables are based on the use of aggregates that meet certain size and grading requirements. The author also provides guidance on how to adjust the proportions of the mix to compensate for variations in the characteristics of the aggregates being used. This book is a valuable resource for anyone involved in the design or production of concrete. It provides a clear and concise guide to the principles of concrete proportioning and can help engineers and contractors to produce high-quality concrete that meets the specified strength requirements.
