Strength and Related Properties of Concrete addresses the most important single property of concrete - its strength - with the goal of contributing to concrete's technical and economical improvement. The book is unique in containing, in a single volume, all of the quantitative tools needed to evaluate, understand, and improve concrete quality. This hands-on guide demonstrates how to fine-tune the composition of concrete to maximize its strength. It presents the best numerical relationships for concrete technology that are currently available, examines them experimentally, and illustrates their practical applications. It also provides a basis for improving both the fundamentals of concrete technology and the way this technology is taught to engineering students. Computerized formulas for strength testing are included on a floppy disk. Anyone involved in concrete technology, from engineers to concrete manufactures will find this practical reference back an indispensable tool.

Concrete: Properties and Manufacture describes the properties of concrete, including its manufacture and use in civil engineering construction. The book first discusses the properties of plastic or wet and hardened concrete. The text also describes different concrete materials, including cement, Portland cement, slag and high alumina cements, and aggregates. The selection also looks at the mix design of concrete. Mix proportioning based on strength and workability; mix design for high alumina cement; combination of single-sized aggregates; and nominal mixes are discussed. The text also examines the manufacture of concrete. Handling and batching of materials, mixing and placing, compaction of concrete, and winter concreting are underscored. The book also focuses on the resistance of concrete to deterioration. Resistance of concrete to freezing, sewage, sulfate attack, chemicals, fire, erosion, and abrasion are discussed. The text also offers information on surface treatment of concrete and special concrete. The selection is a valuable source of information for readers, students, and graduate and site engineers.

Transport Properties of Concrete covers how to measure the ability of ions and fluids to move through concrete material, and how to use the results to model performance. These transport properties largely determine the durability of concrete and of steel embedded within it, as well as the effectiveness of structures such as landfill containment barriers. The book begins by explaining in detail what transport properties are and how to write computer models for transport processes. Early chapters present and explain computer models written in basic code. Coverage then proceeds to a wide range of tests for the transport properties of concrete, and methods for calculating the values for these properties from the test results using analytical and numerical models. The final chapters then show how the values obtained can be used to predict the durability of reinforced concrete, to model the effect of gas pressure, and to model waste containment structures. A number of practical examples are given, in which the calculations and computer models have been applied to real experimental data. Transport Properties of Concrete provides a comprehensive examination of the subject, and will be of use to all concerned with the durability and effectiveness of concrete structures. Provides a detailed understanding of the various transport mechanisms that take place during testing in concrete Shows how to obtain fundamental transport properties

The response of concrete under tensile loading is crucial for most applications because concrete is much weaker in tension than in compression. Understanding the response mechanisms of concrete under tensile conditions is therefore key to understanding and using concrete in structural applications. Understanding the tensile properties of concrete summarises key recent research in this important subject. After an introduction to concrete, the book is divided into two parts: part one on static response and part two on dynamic response. Part one starts with a summary chapter on the most important parameters that affect the tensile response of concrete. Chapters show how multi scale modelling is used to relate concrete composition to tensile properties. Part two focuses on dynamic response and starts with an introduction to the different regimes of dynamic loading, ranging from the low frequency loading by wind or earthquakes up to the extreme dynamic conditions due to explosions and ballistic impacts. Following chapters review dynamic testing techniques and devices that deal with the various regimes of dynamic loading. Later chapters highlight the dynamic behaviour of concrete from different viewpoints, and the book ends with a chapter on practical examples of how detailed knowledge on tensile properties is used by engineers in structural applications. Drawing on the work of some of the leading experts in the field, Understanding the tensile properties of concrete is a valuable reference for civil and structural engineers as well as those researching this important material.

Understanding the rheological properties of fresh concrete, the hydration phenomenon of cement responsible for structuration, the relationship between the characteristics of the porous solid obtained and its mechanical performances or resistance to the aggressive penetration requires a complex knowledge of the physicochemistry of reactive porous materials. The development of simple formulation rules therefore requires the assimilation of this knowledge and a good command of the properties of these materials. The purpose of this book is to provide the mix designer with useful knowledge on granular materials and porous materials, which will enable the innovative design of concrete. Topics covered include the characterization of granular materials, the concepts of porosity and specific surface area, and the transport properties (diffusion and permeation) of concrete. Some of these topics are already covered in other general books dedicated to granular or porous materials. The objective here is to bring them together in one book by adapting them for use by concrete specialists. Applications in the form of exercises are offered at the end of each chapter to enable readers to assimilate the theoretical knowledge and to apply such knowledge to concrete problems encountered in civil engineering. Contents 1. Description of Granular Materials, Definitions. 2. Granulometry. 3. Specific Surface Area of Materials. 4. Voids in Granular Materials and the Arrangement of Grains. 5. Voids in Concrete. 6. The Fundamentals of Diffusion. 7. Permeability.
