Download or read book Science and Technology of Concrete Admixtures written by Pierre-Claude Aïtcin and published by Woodhead Publishing. This book was released on 2015-11-12 with total page 668 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

This book was released on 2013-09-24 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present the latest findings in the properties and application of Supplementary Cementing Materials and blended cements currently used in the world in concrete. Sustainability is an important issue all over the world. Carbon dioxide emission has been a serious problem in the world due to the greenhouse effect. Today many countries agreed to reduce the emission of CO2. Many phases of cement and concrete technology can affect sustainability. Cement and concrete industry is responsible for the production of 7% carbon dioxide of the total world CO2 emission. The use of supplementary cementing materials (SCM), design of concrete mixtures with optimum content of cement and enhancement of concrete durability are the main issues towards sustainability in concrete industry.

Available in PDF, EPUB and Kindle. Book excerpt: The influence of high calcium fly ash as clinker replacement in blended cements on the resistance of concrete structures to the carbonation is presented. The paper concerns of five blended cements made with different contents of supplementary cementitious materials: high and low calcium fly ash and ground granulated blastfurnance slag and one reference cement – Portland cement. The aim was to study the carbonation depth on several concretes designed with a constant water to binder ratio and with various blended cements. Additionally, the prediction of the maximum carbonation depth was proposed. The evaluation of the microstructure was performed using optical microscopy on thin sections in transmitted light. The best results according to the resistance to carbonation achieved the concretes made with Portland-fly ash cement where 14.3 % of high calcium fly ash was used. CEM II/A-W can be used to prove the fc28 and resistance to carbonation for XC3 class.

Download or read book Brittle Matrix Composites written by Mariusz Dabrowski and published by Elsevier Inc. Chapters. This book was released on 2012-11-12 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of aggregate type on the compressive strength, the resistance to chloride penetration and the scaling resistance with de-icing salts of concrete made with blended cements with calcerous fly ash was investigated. The range of investigation included the air entrained concrete with water to cement ratio w/c=0.45 with the prototype blended cements containing the additives of calcerous fly ash, siliceous fly ash and ground granulated blast furnace slag. Concrete specimens were cured during first 3 days in water and then in the air of 40% RH until 28 and 90 days. Frost-salt scaling tests were performed using 3% NaCl solution. The air void microstructure was quantitatively evaluated. The results revealed the influence of blended cement type on the properties of concrete with different type of aggregates.
Download or read book The Technical and Economic Benefits of Blended Cements written by Vute Sirivivatnanon and published by . This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been an increase in requirements for concretes having better quality. The use of blended cements combined with chemical admixtures has offered a wide scope for tailoring concrete to meet these increasing demands. This paper focuses on some of the technical and economic benefits of blended cements in the production of High Performance Concrete (HPC) in Australia in the last few years. While silica fume is commonly used to enhance strength to produce high strength concrete (HSC), fly ash and ground granulated blast furnace slag (slag) have been widely used to provide longer term strength and to improve the workability and control of the heat of hydration of HSC. In marine or aggressive sulphate environments, both slag and/or fly ash have been used to improve the chloride and sulphate resistance of concrete. More recently, silica fume concrete has also found its use in marine applications. The properties of concrete specified for a number of major structures and how these properties were achieved with blended cements will be discussed. The most significant economic gain from the use of these concretes is expected to be derived from the increased service life and reduced maintenance cost. However, some short-term savings have also been achieved and discussed. Examples of these facilities are the Sydney Harbour Tunnel, the Sea Wall of the new Parallel Runway at Sydney Kingsford Smith Airport, the Melbourne Central and Sydney Market City project.
