Book Description
Paper 1: The pore-size distribution present in some carbonate rocks was determined as part of an investigation concerned with the properties of aggregate which affect the durability of portland cement concrete. Paper 2: 52 concrete aggregates were evaluated by means of the rapid chemical test for potential alkali-aggregate reactivity and the results generally showed good correlation with the data obtained in the mortar bar tests. Paper 3: It is demonstrated that the types of carbonate aggregate from the cedar valley formation in Iowa which have been classed as acceptable or unacceptable on the basis of service records, can also be differentiated on the basis of their reactivity with silica and/or fluoride in aqueous solution. Paper 4: Mixtures of calcium hydroxide, pozzolan, and water were reacted at 100 F for 1 to 6 months, and the reaction products were examined by x-ray diffraction and thermal analysis.
Physical and Chemical Properties of Cement and Aggregate in Concrete
Author: F. BurggraffLea's Chemistry of Cement and Concrete
Author: Peter HewlettPublisher: Elsevier
ISBN: 0080535410
Category : Technology & Engineering
Languages : en
Pages : 1087
Book Description
Lea's Chemistry of Cement and Concrete deals with the chemical and physical properties of cements and concretes and their relation to the practical problems that arise in manufacture and use. As such it is addressed not only to the chemist and those concerned with the science and technology of silicate materials, but also to those interested in the use of concrete in building and civil engineering construction. Much attention is given to the suitability of materials, to the conditions under which concrete can excel and those where it may deteriorate and to the precautionary or remedial measures that can be adopted. First published in 1935, this is the fourth edition and the first to appear since the death of Sir Frederick Lea, the original author. Over the life of the first three editions, this book has become the authority on its subject. The fourth edition is edited by Professor Peter C. Hewlett, Director of the British Board of Agrement and visiting Industrial Professor in the Department of Civil Engineering at the University of Dundee. Professor Hewlett has brought together a distinguished body of international contributors to produce an edition which is a worthy successor to the previous editions.

Book Description
Bringing together in one volume the latest research and information, this book provides a detailed guide to the selection and use of aggregates in concrete. After an introduction defining the purpose and role of aggregates in concrete, the authors present an overview of aggregate sources and production techniques, followed by a detailed study of their physical, mechanical and chemical properties. This knowledge is then applied to the use of aggregates in both plastic and hardened concretes, and in the overall mix design. Special aggregates and their applications are discussed in detail, as are the current main specifications, standards and tests.
Lightweight Aggregate Concrete

Book Description
In spite of the increasing use and demand for lightweight aggregate concrete (LWAC), there is still a lack of adequate explanations to understand the mechanisms responsible for the strength and durability properties of LWAC. This book is written to give an overall picture of LWAC, from the historical background, aggregate production, proportioning and production of concrete, to applications in structures. Physical properties and chemical durability are described in detail. The physical properties include density, strength, shrinkage, and elasticity. Chemical durability includes resistance to acids, chloride ingress, carbonation, and freeze-thaw resistance. Fire resistance is also included, which is seldom considered, but is a very important aspect of the safety of the structure. Microstructure development and its relation to the durability properties of LWAC generally are not highlighted in the literature. The development of bonds, the microstructure with different binder systems, and different types of lightweight aggregates are explained. They show how lightweight aggregate concrete differs from normal weight concrete. The chapters on chloride ingress and freeze-thaw resistance are detailed because of the use of LWAC in offshore construction. The economical aspects of using LWAC are also reviewed. Emphasis is placed on the fact that although the cost of LWAC is high, the total cost of construction has to be considered, including the cost of transport, reinforcement, etc. When these are considered then LWAC becomes cheaper and attractive. The life cycle cost of the concrete is another consideration for calculating long-term savings on maintenance costs.

Physical Properties of Concrete and Concrete Constituents

ISBN: 111856295X
Category : Technology & Engineering
Languages : en
Pages : 242
Book Description
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.
