DOWNLOAD EBOOKConcrete is the most used man-made material in the world since its invention. The widespread use of this material has led to continuous developments such as ultra-high strength concrete and self-compacting concrete. Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste focuses on the recent development which the use of various types of recycled waste materials as aggregate in the production of various types of concrete. By drawing together information and data from various fields and sources, Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste provides full coverage of this subject. Divided into two parts, a compilation of varied literature data related to the use of various types of industrial waste as aggregates in concrete is followed by a discussion of the use of construction and demolition waste as aggregate in concrete. The properties of the aggregates and their effect on various concrete properties are presented, and the quantitative procedure to estimate the properties of concrete containing construction and demolition waste as aggregates is explained. Current codes and practices developed in various countries to use construction and demolition waste as aggregates in concrete and issues related to the sustainability of cement and concrete production are also discussed. The comprehensive information presented in Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste will be helpful to graduate students, researchers and concrete technologists. The collected data will also be an essential reference for practicing engineers who face problems concerning the use of these materials in concrete production.

DOWNLOAD EBOOKThis book focuses on the utilisation of construction waste material as coarse aggregate in making concrete. It discusses in detail the behaviour of recycled aggregate under impact load along with other structural applications, and explains the various quality-improvement techniques for recycled aggregate and recycled aggregate concrete (RAC). The first chapter describes the importance of recycling construction and demolition waste and the status quo of global construction and demolition waste recycling. The second chapter examines the recycled aggregate production methodology. Subsequent chapters address the physical and mechanical characteristics and different research findings, as well as the engineering properties of recycled aggregate concrete. Further, the interrelationships among the mechanical properties of recycled aggregate concrete are discussed. The book also explores long-term properties like shrinkage and creep, durability properties, and microstructural characterisation. It will serve as a valuable resource for researchers and professionals alike.

DOWNLOAD EBOOKA novel method of concrete mix design is presented. Tests with various constituent materials are reported in great detail. Both laboratory tests and applications in industry show the method to be very successful for all kinds of normal constituent materials, including silica fume, ground granulated blast furnace slag, fly ash, natural pozzolans, blended cement, fine and coarse aggregates, water, air entraining admixtures, plasticizers and super-plasticizers.
A Conceptual Model for Designing Recycled Aggregate Concrete for Structural Applications

DOWNLOAD EBOOKThis book reports on the physical and mechanical characterization of Recycled Aggregate Concrete (RAC), produced through a partial-to-total replacement of ordinary aggregates with what have been dubbed Recycled Concrete Aggregates (RCAs). It proposes a theoretical framework for understanding the relationships between RCAs and RCA, and for predicting the resulting behavior of RAC. The book demonstrates that in the case of RAC two additional parameters have to be taken into account than with ordinary aggregates, due to the composite nature and higher porosity of RCAs. By extending Abrams’ Law for Recycled Aggregate Concrete, it represents a first step in the formulation of a general model for predicting the properties of RAC. The theoretical approach presented here addresses an important gap in the literature and is expected to stimulate new research on the use of this more sustainable form of concrete in structural applications.

DOWNLOAD EBOOKBringing 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.

DOWNLOAD EBOOKThis book presents an in-depth approach to concrete ingredients and their relationships to concrete by discussing their properties, pertinent test methods, specifications, proper use and selection, and solutions to problems in practice. The approach is practice oriented, and the book assists in the improved application of concrete through a thorough understanding of its ingredients. This is aided by the discussion of certain fundamental aspects and relationships in quantitative forms, and by also presenting the interpretation of research and experience. An extensive bibliography is included.The book is a current, organized summary of knowledge concerning concrete-making materials, which will enable the engineer/user to make the best possible product using these materials.

DOWNLOAD EBOOKAn investigation was conducted to determine if improvement in quality of concrete could be obtained by adjustments in the Nebraska aggregate specification. The tests included compressive strength tests on concrete prepared with three different maximum aggregate sizes (3/8 in, 3/4 in, and 1 1/2 in) and four different percentages of fine aggregate (40%, 50%, 60%, and 70%) making 12 combinations. All mixes contained six bags of cement per cu. yd., 5 to 7% air and 1 to 3-inch slump. The results of these tests are as follows: No increase in compressive strength can be expected with adjustments in aggregate gradation. The mixing water requirement decreased as the maximum coarse aggregate size increased. Also, the water requirements increased as percentage of fine aggregate increased. The workability of the concrete improved as the percentage of fine aggregate was increased and when maximum aggregate size was limited to 3/4 in. (Author)

DOWNLOAD EBOOKMaster's Thesis from the year 2018 in the subject Engineering - Civil Engineering, grade: A, , course: Masters in Structural Engineering, language: English, abstract: Pervious concrete is a concrete which allows the water to pass through it. The pervious concrete contains cement, coarse aggregates, water and admixtures if needed. It has no sand in it which results in large amount of voids in the previous concrete. This sole property of having voids play a vital role in the functioning of the pervious concrete i.e; allowing water to pass through it. The pervious concrete has a disadvantage that it has less compressive strength when compare to normal concrete this backdrop in pervious concrete because pervious concrete is a no fines concrete it has no sand the sand which plays a vital role in the strength gain of the concrete hence we in our study has concentrated in improving the compressive strength but at the same time the permeability and void content should also not affected because permeability and void content are two most important properties of the pervious concrete which makes it the pervious concrete so basically we have also conducted study on the permeability and void content of the pervious concrete. In our study we have added different sizes of coarse aggregates such as 20 m, 12 mm, 12 +2 0 mm and we have added the sand percentages at 0 %, 0.25 %, 0.75 % and the compressive strength was checked on 7,14,28,56,90 days respectively and we have checked the permeability and void content at 28 days.
