Frost Durability of Roller-Compacted Concrete Pavements
The growth of roller-compacted concrete pavement use in cold climate regions often is impeded by concerns regarding its ability to resist frost attack. Most published laboratory test results have indicated that the frost resistance and particularly the deicer salt-scale resistance of RCC are not always satisfactory. However, long-term field performance indicates that non-air entrainment RCC can be quite resistant to frost action. The report provides a comprehensive review on the current practices and recent developments in material selection and aggregate gradation, mixture design methods, production process and placement techniques. Improved construction techniques and recent developments in mixture design methods have resulted in stronger more durable RCC. Data shows that as little as 1.5% of spherical air bubbles can have a beneficial influence on the frost resistance durability of RCC. Test results indicate that ASTM C 1262 appears to be a reliable method of assessing the frost durability of RCC.

Limit State Design Of Reinforced Concrete by P. C. Varghese
Author: P C varghese | Size: 22 MB | Format: PDF | Publisher: prentice hall | Year: 1999 | pages: 566 | ISBN: 8120320395
Book Summary of Limit State Design Of Reinforced Concrete
This substantially revised second edition takes into account the provisions of the revised Indian Code of practice for Plain and Reinforced Concrete IS 456 : 2000. It also provides additional data on detailing of steel to make the book more useful to practicing engineers. The chapter on Limit State of Durability for Environment has been completely revised and the new provisions of the code such as those for design for shear in reinforced concrete, rules for shearing main steel in slabs, lateral steel in columns, and stirrups in beams have been explained in detail in the new edition.
This comprehensive and systematically organized book is intended for undergraduate students of Civil Engineering, covering the first course on Reinforced Concrete Design and as a reference for the practicing engineers. Besides covering IS 456 : 2000, the book also deals with the British and US Codes. Advanced topics of IS 456 : 2000 have been discussed in the companion volume Advanced Reinforced Concrete Design (also published by Prentice-Hall of India). The two books together cover all the topics in IS 456 : 2000 and many other topics which are so important in modern methods of design of reinforced concrete.

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.

Fatigue of Fiber-reinforced Composites - Engineering Materials and Processes
Author: Anastasios P. Vassilopoulos, Thomas Keller | Size: 3.3 MB | Format: PDF | Publisher: Springer | Year: 2011 | pages: 280 | ISBN: 1849961808
Fatigue has long been recognized as a mechanism that can provoke catastrophic material failure in structural applications and researchers are now turning to the development of prediction tools in order to reduce the cost of determining design criteria for any new material. Fatigue of Fiber-reinforced Composites explains these highly scientific subjects in a simple yet thorough way.
Fatigue behavior of fiber-reinforced composite materials and structural components is described through the presentation of numerous experimental results. Many examples help the reader to visualize the failure modes of laminated composite materials and structural adhesively bonded joints. Theoretical models, based on these experimental data, are demonstrated and their capacity for fatigue life modeling and prediction is thoroughly assessed.
Fatigue of Fiber-reinforced Composites gives the reader the opportunity to learn about methods for modeling the fatigue behavior of fiber-reinforced composites, about statistical analysis of experimental data, and about theories for life prediction under loading patterns that produce multiaxial fatigue stress states. The authors combine these theories to establish a complete design process that is able to predict fatigue life of fiber-reinforced composites under multiaxial, variable amplitude stress states. A classic design methodology is presented for demonstration and theoretical predictions are compared to experimental data from typical material systems used in the wind turbine rotor blade industry.
Fatigue of Fiber-reinforced Composites also presents novel computational methods for modeling fatigue behavior of composite materials, such as artificial neural networks and genetic programming, as a promising alternative to the conventional methods. It is an ideal source of information for researchers and graduate students in mechanical engineering, civil engineering and materials science.

well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers ,
Often ,
highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others ,
However ,
the accelerating growth of highway transportation develops increasingly complex problems of wide interest to highway authorities ,
These problems are best studied through a coordinated program of cooperative research ,
In recognition of these needs ,
the highway administrators of the American Association of State Highway and Transportation Officials initiated in 1962 an objective national highway research program employing modern scientific techniques ,
This program is supported on a continuing basis by funds from participating member states of the Association and it receives the full cooperation and support of the Federal Highway Administration ,
United States Department of Transportation ,
The Transportation Research Board of the National Academies was requested by the Association to administer the research program because of the Board’s recognized objectivity and understanding of modern research practices ,
The Board is uniquely suited for this purpose as it maintains an extensive committee structure from which authorities on any highway transportation subject may be drawn; it possesses avenues of communications and cooperation with federal ,
state and local governmental agencies ,
universities ,
and industry; its relationship to the National Research Council is an insurance of objectivity; it maintains a full-time research correlation staff of specialists in highway transportation matters to bring the findings of research directly to those who are in a position to use them ,
The program is developed on the basis of research needs identified by chief administrators of the highway and transportation departments and by committees of AASHTO ,
Each year ,
specific areas of research needs to be included in the program are proposed to the National Research Council and the Board by the American Association of State Highway and Transportation Officials ,
Research projects to fulfill these needs are defined by the Board ,
and qualified research agencies are selected from those that have submitted proposals ,
Administration and surveillance of research contracts are the responsibilities of the National Research Council and the Transportation Research Board ,
The needs for highway research are many ,
and the National Cooperative Highway Research Program can make significant contributions to the solution of highway transportation problems of mutual concern to many responsible groups ,
The program ,
however ,
is intended to complement rather than to substitute for or duplicate other highway research programs http://ifile ,

99 MB | Format: PDF | Publisher: TRANSPORTATION RESEARCH BOARD | Year: 2006 | pages: 56 Causes of Cracking oncrete structures do not frequently fail due to lack of strength ,
rather due to inadequate durability or due to improper maintenance techniques ,
The most common cause of premature deterioration is attributed to the development of cracks (Mehta ,
1992; Hobbs ,
1999) ,
Cracking can occur in concrete pavements and structures for several reasons that can primarily be grouped into either mechanical loading or environmental effects ,
It should also be noted that for most practical structures ,
reinforcement is used to bridge and hold cracks together when they develop ,
thereby assuring load transfer while adding ductility to a relatively brittle material ,
Therefore not all cracking causes concern ,
Reinforced concrete elements are frequently designed on the assumption that cracking should take place under standard loading conditions (Nilsson and Winter ,
1985; Nawy ,
2000) ,
For example continuously reinforced concrete pavements (CRCP) are designed with longitudinal steel in an amount adequate to hold shrinkage cracks tight ,
while joints exist only at locations of construction transitions and on-grade structures ,
In this pavement type wherein shrinkage cracks develop over time and stabilize over the first 3 to 4 years ,
cracking in the transverse direction in specific patterns is not detrimental to the structure as long as the cracks remain tight and retain good load transfer ,
Therefore ,
cause of cracking should be carefully identified to determine which cracks are common and acceptable and which cracks merit repair or further investigation ,
Several guides currently exist to assist in determining the cause of cracking including the American Concrete Institute (ACI) committee reports “Guide for Making and Condition Survey of Concrete in Service” (ACI 201-92) and “Causes ,
Evaluation and Repair of Cracks in Concrete Structures” (ACI 224-R93) ,
Mechanical loads induce strains that can exceed the strain capacity (or strength capacity) of concrete ,
thereby causing cracking ,
Concrete may be particularly susceptible to cracking that occurs at early-ages when concrete has a low tensile capacity (Kasai ,
1972) ,
If the loads are applied repeatedly or over a long period of time ,
fatigue and creep can affect the strain (or strength) development that can lead to failure (Bazant and Celodin ,
1991) or reduce stresses (Shah et al ,
,
1998) ,
Although numerous factors influence whether concrete would be expected to crack due to environmental effects ,
it can be simply stated that cracking will occur if the stress that develops in response to internal expansion or the restraint of a volumetric contraction that results in stress development exceeds the strength (or fracture resistance) of the material ,
Internal expansion is primarily caused by chemical attack or freezing of the pore water while volumetric contraction is typically attributed to moisture changes ,
chemical reactions ,
and thermal changes http://ifile ,

9 MB | Format: PDF | Publisher: The Concrete Society | Year: 2004 | pages: 78 | ISBN: 1904482090 General The NSCS remains laid out in terms of process rather than in terms of materials and workmanship ,
British Standards are referenced rather than reproduced ,
Where the NSCS is at variance with British Standards ,
the NSCS is to be used ,
The NSCS covers requirements for the construction of concrete building structures of in-situ concrete ,
precast concrete ,
and hybrid concrete systems ,
It is especially relevant for structures designed to BS 8110 and EN 1992 (EC2) ,
Where the NSCS is to be used for structures in extreme environments ,
those produced by specialist construction techniques or those of a specialist design nature ,
Part 2 ,
Project specification ,
should include the appropriate particular requirements ,
The NSCS is written with safety in mind but does not specify health and safety requirements as these are covered by legal regulations that apply to all construction and are outside the scope of this specification ,
Where specifications ,
standards or regulations are referenced ,
readers should ensure that they refer to the latest editions ,
NSCS Part 1 ,
Standard specification Specific obligations are placed on the Specialist Concrete Contractor ,
the Employer and the Engineer ,
In some cases these will be different organisations; sometimes any or all will be represented by the same organisation ,
However ,
their responsibilities remain as required under the Contract ,
NSCS Part 2 ,
Project specification This part is to be read in conjunction with NSCS Part 1 and outlines project information specific to a particular project and additional to the requirements of NSCS Part 1 ,
Part 2 covers the exchange of information necessary between the Employer and Specialist Concrete Contractor at both tender stage and contract stage ,
The relevant sections of Part 2 should be completed at the appropriate stage ,
Part 2 allows the Engineer responsible for the design the freedom to incorporate specific Clauses to vary the standard Clauses of Part 1 ,
It is emphasised that NSCS Part 1 has been produced as a non-prescriptive specification and therefore any amendments through NSCS Part 2 should be as few as possible ,
The pro-forma layout of Part 2 acts as an aide memoire to the disclosure of relevant information for most types of project ,
To aid the task of preparing a Project specification ,
permission is hereby expressly given for users of this document to copy any part or the whole of Part 2 ,
Project specification ,
without infringement of copyright ,
A data disc is enclosed to enable easy electronic completion and distribution ,
NSCS ,
Guidance notes The Guidance notes are for information only and do not form part of the Specification ,
They provide background information on the content of the Supplement Parts 1 and 2 and explain why certain Clauses have been adopted ,
They include reference to the terminology changes used in the new Standards ,
which may be strange for UK users and are designed to be ‘dipped into’ and read with the relevant clauses in Parts 1 and 2 ,
As a result there is some intentional duplication http://ifile ,

1 MB | Format: PDF | Publisher: The Concrete Centre | Year: 2010 | pages: 132 | ISBN: 9781904818960 The NSCS has the same scope as BS EN 13670 for Building Structures ,
The NSCS is laid out in terms of processes ,
and it uses the same sequence as BS EN 13670 ,
European and British Standards are referenced rather than reproduced within the document ,
The NSCS covers requirements for the construction of concrete building structures of in-situ concrete ,
precast concrete ,
and hybrid concrete systems ,
It is intended for use with structures designed to BS EN 1992 ,
although it can be used when other design standards are used ,
Where the NSCS is to be used for structures in extreme environments ,
those produced by specialist construction techniques or those of a specialist design nature ,
the Project Specifi cation should include the particular requirements where appropriate ,
It is expected that the requirements for concrete in more specialist geotechnical works will be covered by a specifi cation such as the ICE Specifi cation for piling and embedded retaining walls (SPERW) ,
The NSCS should be coordinated where required with other project specifi cations such as the SPERW ,
The NSCS is written with safety in mind but does not specify Health and Safety requirements as they are legal regulations that apply to all construction and are inherent within this specifi cation ,
Where specifi cations ,
standards or regulations are referred to they shall refer to the latest editions unless reference is made to a specifi c dated clause in a standard ,
Specifi c obligations are placed on the Constructor ,
the Employer and the Engineer ,
In some cases these will be different organisations; sometimes any or all will be represented by the same organisation ,
However ,
their responsibilities remain as required under the Contract ,
The NSCS Project Specifi cation is to be read in conjunction with this Standard Specifi cation and outlines project information specifi c to a particular project that is additional to the requirements of Standard Specifi cation ,

77 MB | Format: PDF | Publisher: RTA Road Network Infrastructure Directorate | Year: 2005 | pages: 36 | ISBN: 1920907300 The use of shotcrete has recently come under scrutiny ,
Although it is cost effective and useful ,
when used in its natural ,
untreated state ,
it is visually intrusive ,
particularly in highly sensitive urban or rural areas ,
Due to its poor visual qualities there is often a call to restrict its use ,
However ,
this is not possible as it is a valuable engineering technique ,
useful for stabilising and providing structural support for problematic slopes ,
This has unnecessarily caused a difference of opinion within road design teams because if considered at the outset ,
in the route selection and concept design stages ,
designers and engineers can agree on a common goal to avoid the need for slope stabilisation for visual as well as cost and maintenance reasons ,
Therefore this document addresses the need to consider unstable slopes early on in the road development process and sets down a strategy and recommendations to avoid or minimise the eventual need for shotcrete ,
However it also recognises that there will be circumstances where shotcrete is inevitably required and addresses the real practical problem of what is an acceptable appearance http://ifile ,
