This book was released on 2015-11-12 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science and Technology of Concrete Admixtures presents admixtures from both a theoretical and practical point-of-view. The authors emphasize key concepts that can be used to better understand the working mechanisms of these products by presenting a concise overview on the fundamental behavior of Portland cement and hydraulic binders as well as their chemical admixtures, also discussing recent effects in concrete in terms of rheology, mechanics, durability, and sustainability, but never forgetting the fundamental role played by the water/binder ratio and proper curing in concrete technology. Part One presents basic knowledge on Portland cement and concrete, while Part Two deals with the chemical and physical background needed to better understand what admixtures are chemically, and through which mechanism they modify the properties of the fresh and hardened concrete. Subsequent sections present discussions on admixtures technology and two particular types of concrete, self-consolidating and ultra-high strength concretes, with final remarks on their future. Combines the knowledge of two leading authors to present both the scientific and technology of admixtures Explains what admixtures are from a chemical point-of-view and illustrates by which mechanisms they modify the properties of fresh and hardened concrete Presents a fundamental, practical, and innovative reference book on the topic Contains three detailed appendices that can be used to learn how to use admixtures more efficiently

Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition ten years ago, significant developments have occurred in the use of admixtures in concrete. Eight new chapters and a full update of the preceding ten chapters bring this book up to date; reflecting the relative advances made in the science and technology of different groups of admixtures. The increased role and development of admixtures in concrete technology is evidenced by a number of conferences, publications, and novel admixtures available in the market place. These developments in the field caused the modification of many chapters in the first edition in order to reflect the advances. Although individual chapters refer to standards and specifications of admixtures, those only interested in the standards or techniques used in investigating admixtures will find the second chapter (Research Technologies, Standards, and Specifications) useful. Admixtures are not as inert as may be presumed. They may chemically interact with the constituents of concrete and affect the properties of the fresh and hardened concrete and its durability. The third chapter deals with these aspects. It was important to devote a chapter to recent attempts in developing new admixtures.

For each mineral admixture, the book looks at manufacturing and processing, physical characteristics, chemical and mineralogical composition, quality control, and reported experiences. It also examines the provisions of national standards on the admixture’s addition to cement and concrete. References to microstructures and chemistry are kept to a minimum and only discussed to the extent necessary to help readers apply the admixtures in practice. The book also addresses hydration, presenting the relevant chemistry and detailing the impact of adding mineral admixtures to concrete. A chapter on strength and durability explains the mechanisms, models, and standards related to concrete deterioration and how to mitigate carbonation, alkali-aggregate reactions, chloride attack and corrosion of reinforcement, external and internal sulphate attack, decalcification, and freeze-thaw action. This book is a useful reference for practicing engineers and students alike. It brings together, in one volume, information on the materials, hydration, and the strength and durability of cement and concrete with mineral admixtures. Offering a deeper understanding of mineral admixtures, it encourages engineers to more effectively use these and other wastes in cement and concrete to support more sustainable growth of the cement and construction industry.

Book excerpt: Concrete, a construction material, is widely used because of its excellent properties such as durability, workability, satisfactory strength, and the easy availability of raw materials (cement, aggregates, and water), which are used to produce it. In recent years, the demand for ready-mix concrete (RMC) has increased rapidly. The primary reasons behind this are convenience of using RMC in high-rise structures, shortage of space at construction site, saving of time related to the preparation of concrete on-site, and better quality of RMC compared to the conventional concrete. To produce a concrete with specific requirements such as high performance concrete (HPC), additives and admixtures are added to raw materials of normal concrete to improve some properties by pozzolanic and physical actions. Nowadays, the concrete admixtures are widely used in the construction projects. The main types of chemical admixtures can be summarized as plasticizers, accelerating/retarding agents, air entraining agents, waterproofing additives and others such as corrosion inhibitors and coloring agents etc. The benefits derived from the use of chemical admixtures include improved durability, strength, chemical resistance, coloring, reduction in water and cement requirement and enhanced working properties of concrete. These admixtures improve the concrete microstructure by making it denser, more homogeneous, and uniform, leading to enhance its properties such as strength and durability compared to the plain mix. Chemical Admixtures for Concrete covers the theory and real world cases to understand the effects of different types of chemical admixture on properties of concrete. Effects of different chemical admixtures on fresh and hardened properties of prolonged mixed concrete and their cost-effectiveness were investigated. Influence of sand to aggregate volume ratio, cement content, and use of chilled mixing water on the properties of prolonged mixed concrete was studied as well. Presenting information on the materials, hydration, and the strength and durability of cement and concrete with mineral admixtures; this book will appeal to practicing engineers and students alike.

This book was released on 2016-01-11 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1930 more than 100,000 new chemical compounds have been developed and insufficient information exists on the health assessment of 95 percent of these chemicals in which a relevant percentage are used in construction products. For instance Portland cement concrete, the most used material on the Planet (10.000 million tons/year that in the next 40 years will increase around 100 %) currently used in around 15% of total concrete production contains chemicals used to modify their properties, either in the fresh or hardened state. Biopolymers are materials that are developed from natural resources. They reduce dependence on fossil fuels and reduce carbon dioxide emissions. There is a worldwide demand to replace petroleum-based materials with renewable resources. Currently bio-admixtures represent just a small fraction of the chemical admixtures market (around 20%) but with environmental awareness for constituents in construction materials generally growing (the Construction Products Regulation is being enforced in Europe since 2013), the trend towards bio-admixtures is expected to continue. This book provides an updated state-of-the-art review on biopolymers and their influence and use as admixtures in the development of eco-efficient construction materials. Provides essential knowledge for researchers and producers working on the development of biopolymer-modified construction materials Discusses the various types of biopolymers currently available, their different production techniques, their use as bio-admixtures in concretes and mortars and applications in other areas of civil engineering such as soil stability, wood preservation, adhesives and coatings All contributions are made from leading researchers, who have intensive involvement in the design and use of biopolymers in construction materials

This book was released on 2023-01-05 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt:  Cement is a powdery substance made by calcining lime and clay. When cement is mixed with water, it forms mortar, and when it is mixed with sand, gravel, and water, it makes concrete. Mortar is used as a bonding agent for plastering, masonry work, and pointing. Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stones; and the paste is made from water and portland cement mixture. Concrete is used for laying floors, roofs and constructing lintels, beams, pillars and other masonry structures. Concrete products such as pipes, blocks, bricks, and concrete articles are made using concrete. The cement and concrete products market consists of sales of cement and concrete products and related services by entities (organizations, sole traders and partnerships) that manufacture cement and concrete products such as concrete pipes, bricks, and paving blocks. The cement and concrete products manufacturing industry includes establishments engaged in manufacturing portland cement, pozzolanic cement, ready-mix concrete, concrete blocks, bricks, and pipes and related products. The global cement and concrete products market was valued at $333,255.8 million. The market accounted for 0.40% of the global GDP. In terms of per capita consumption, the market accounted for $43.5. The market was also supported by rapid urbanization, and government initiatives towards infrastructure development. Growth in the forecast can be attributed to increasing spending on infrastructure, global economic growth, the development of affordable housing, and a rapidly growing urban population.
