The Romans used an early type of concrete made with natural pozzuolanic cement more than 2,000 years ago. Today, Portland Cement Concrete is the most important material of construction. Yet few books, if any, exist that offer an in-depth analysis of the mixing and testing methods of this vital hydraulic cement. Until now that is. Engineered Concrete: Mix Design and Test Methods helps engineers, as well as laboratory technicians, grasp a better understanding of Portland Cement and Portland Cement Concrete. The book is divided into several sections, with the first, Mix Design Procedures, explaining how concrete batches are designed, mixed, and measured for various consistencies. Another section details the tests of the primary component materials of concrete other than water - namely Portland Cement, aggregates, and mortar - while the final section includes some of the fundamental concrete testing procedures for different strength parameters in conformity with the standards of the American Society for Testing Materials. While focusing solely on Portland Cement, the book also includes information on other hydraulic cementitious materials and additives because of their modern applications. Solidly researched and written, Engineered Concrete: Mix Design and Test Methods provides a clear understanding of mix design and testing of Portland Cement Concrete. As every civil engineer knows, it is the most versatile and important material of construction, and will probably remain so as far into the future as we can see.
