CIB W080 / RILEM 175 SLM Service Life Methodologies Prediction of Service Life for Buildings and Components
Reports compiled by
CIB W080 / RILEM 175-SLM Service Life Methodologies
Prediction of Service Life for Buildings and Components
The State of the Art Reports on methods of service life prediction have been arranged in two parts: A (Factor methods) and B (Engineering design). Each part, individually authored, is self-contained and includes a title page, table of contents, summary, and references and may contain additional information (e.g., preface, abbreviations). References are provided in author date style and are exclusive to the Part in which they are used – they have not been cross-referenced. In order that reference can be made to a specific Table or Figure in the text, these items have been enumerated using a prefix of either A or B pertaining the part in which they are presented. Finally, pagination is continuous over the two parts.

Corrosion of steel reinforcement in concrete is the most common problem affecting the durability of reinforced concrete structures. Chloride-induced corrosion is one of the main mechanisms of deterioration affecting the long-term performance of such structures1. Concrete provides physical and chemical protection to the reinforcing steel from penetrating chlorides which may cause steel depassivation leading to increased risk of steel corrosion.
The chloride resistance depends on the permeability of the concrete and the thickness of cover to the reinforcement. The integrity of the concrete cover under service load, in terms of cracking and crack width, also influences the resistance to penetrating chlorides. Corrosion of steel reinforcement is an electrochemical process. Hence electrochemical properties of concrete, such as resistivity, are important inherent properties affecting the corrosion rate of reinforcing steel.
Metha2 reconfirmed from a review of case studies that it is the permeability of concrete, rather than its chemistry, which is the key to overall durability. The causes of high permeability are not limited to poor concrete proportion but poor concreting practice, such as incomplete mixing, inadequate consolidation and curing after placement, insufficient cover to reinforcing steel, and badly constructed joints. In service, concrete may exhibit various forms of cracking for reasons such as settlement, premature loading, overloads, and repeated impact. To obtain long-term durability of concrete marine structures, the control of concrete cracking in service through proper mix proportioning and concreting practice is of as much importance as the control of concrete permeability.
This report discusses the various factors affecting chloride resistance of concrete, mechanisms of chloride transport, related test methods and performance specifications. It also assesses additional measures to enhance the chloride resistance of concrete.

Building or architectural acoustics is taken in this book to cover all aspects of sound and vibration in buildings. The book covers room acoustics but the main emphasis is on sound insulation and sound absorption and the basic aspects of noise and vibration problems connected to service equipment and external sources. Measuring techniques connected to these fields are also brought in. It is designed for advanced level engineering studies and is also valuable as a guide for practitioners and acoustic consultants who need to fulfil the demands of building regulations.
It gives emphasis to the acoustical performance of buildings as derived from the performance of the elements comprising various structures. Consequently, the physical aspects of sound transmission and absorption need to be understood, and the main focus is on the design of elements and structures to provide high sound insulation and high absorbing power. Examples are taken from all types of buildings. The book aims at giving an understanding of the physical principles involved and three chapters are therefore devoted to vibration phenomena and sound waves in fluids and solid media.
Subjective aspects connected to sound and sound perception is sufficiently covered by other books; however, the chapter on room acoustics includes descriptions of measures that quantify the “acoustic quality” of rooms for speech and music.
Tor Erik Vigran is professor emeritus at the Norwegian University of Science and Technology, Head of the Acoustic Committee of Standards Norway, the Norwegian standardization organization, and member of several working groups within ISO/TC 43 and CEN/TC 126.

Tiebacks in Foundation Engineering and Construction
by Harry Schnabel Jr.
Product Description:
The use of tiebacks has evolved from simple lateral support during construction or excavation, to an increased number of permanent installations. This book examines the process of choosing the right tie-back or anchor for the job and the varying factors that influence those decisions from concept to construction, including corrosion, long-term capacity and soil conditions.

Author: Tim Davis | Size: 9 MB | Format:PDF | Publisher: ASCE Press | Year: 2008 | ISBN: 0784409498
Geotechnical Testing, Observation, and Documentation is an in-depth field manual for soil technicians and geotechnical engineers. This indispensable reference guide designed for use during the investigation, grading, and construction phases of geotechnical projects has helped thousands of readers understand common laboratory and field tests, classify soil accurately, interpret project recommendations, and document the entire construction monitoring process.
This updated and expanded edition offers new material on topics such as deep foundations, shallow foundations, retaining walls, and loss prevention. Sample test questions appear at the end of every chapter, and a comprehensive case study presents each step of a sample project, from site investigation and lab work through construction and documentation. A quick reference chapter summarizes current tools and references, evaluates compaction equipment, and presents frequently used formulas and equations. The appendixes offer a glossary with more than 500 geotechnical terms, an answer key to chapter questions, and a collection of blank ready-to-use forms.
Geotechnical Testing, Observation, and Documentation, Second Edition, is valuable for training new technicians and provides a refresher course for veterans. Soil technicians contemplating the NICET or ICC certification exams will find Tim Davis' book an essential test preparation aid.
