Book Description
Concrete is a composite construction material made primarily with aggregate, cement, and water. There are many formulations of concrete, which provide varied properties, and concrete is the most used man-made product in the world. Concrete is widely used for making architectural structures, foundations, brick/block walls, pavements, bridges, dams, pools/reservoirs, even boats etc. There is a general view that the size of coarse aggregate affects only the properties of fresh concrete and it is impact on hardened properties is insignificant. This book presents the impact of different sizes of coarse aggregate on fresh and hardened properties of concrete. While slump cone test evaluated the fresh concrete properties, compressive strength test determined the hardened state properties by using concrete mixtures that proportioned with three types of cements. Graded coarse aggregates with maximum aggregate size were selected for this experimental program for each cement. The results show that while the coarse aggregate size influences the slump, it is not relevant to compressive strength. The latter properties are governed by (w/b) ratio, cement type and cement content.

Aggregates in Concrete
Author: Mark Alexander
Publisher: CRC Press
ISBN: 0203963695
Category : Technology & Engineering
Languages : en
Pages : 448
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.

Effect of Larger Sized Coarse Aggregates on Mechanical Properties of Portland Cement Concrete Pavements and Structures

Publisher:
ISBN:
Category : Pavements, Concrete
Languages : en
Pages : 172
Book Description
ODOT is continually searching for ways to improve the cost efficiency of Portland cement concrete without sacrificing concrete strength and stiffness. Because Portland cement is easily the most costly material used in normal concrete, limiting the amount of cement used is the quickest way to achieve cost effectiveness. In addition, limiting the cement content will also help to prevent dimensional instabilities in concrete such as shrinkage and creep. The use of larger sized coarse aggregates may be useful in limiting cement content, yet larger sized coarse aggregates may also decrease concrete strength by weakening the aggregate-cement paste bond. In many transportation structures, such as pavements, concrete strength is not critical, as dimensional stability, porosity, and durability play a more important role. It is possible, therefore, that larger sized coarse aggregates can reduce the cement content and improve these properties. Laboratory research is needed to determine if larger sized coarse aggregates can improve cement efficiency without reducing concrete strength.

Concrete Technology
Author: Adam M. Neville
Publisher:
ISBN: 9780273732198
Category : Cement
Languages : en
Pages : 442
Book Description
The success of any concrete structure depends on the designer's sound knowledge of concrete and its behaviour under load, under temperature and humidity changes, and under exposure to the relevant environment and industrial conditions. This book gives students a thorough understanding of all aspects of concrete technology from first principles. It covers concrete ingredients, properties and behaviour in the finished structure with reference to national standards and recognised testing methods used in Britain, the European Union and the United States. Examples and problems are given throughout to emphasise the important aspects of each chapter. An excellent coursebook for all students of Civil Engineering, Structural Engineering and Building at degree or diploma level, Concrete Technology will also be a valuable reference book for practising engineers in the field.

Book Description
An important new state-of-the-art report prepared by RILEM Technical Committee 108 ICC. It has been written by a team of leading international experts from the UK, USA, Canada, Israel, Germany, Denmark, South Africa, Italy and France. Research studies over recent years in the field of cement science have focused on the behaviour of the interfaces between the components of cement-based materials. The techniques used in other areas of materials science are being applied to the complex materials found in cements and concretes, and this book provides a significant survey of the present state of the art.
