Steel Corrosion Induced Concrete Cracking presents the latest advances in the origin, mechanism and development of corrosion-induced cracking in concrete. It investigates topics including expansion coefficient and elastic modulus of steel corrosion, rust layer and rust distribution, spatial distribution of corrosion products, the shape of corrosion-induced cracks and so on.
This book concludes by proposing an improved corrosion-induced cracking model, which considers the phenomena of the simultaneous occurrence of corrosion layer accumulation and corrosion filling in concrete.
This book will be a valuable reference book for researchers and graduate students in the field of concrete durability and concrete structure, and industry engineers who are concerned with the deterioration mechanisms and the life cycle of reinforced concrete structures.
Proposes a new corrosion-induced concrete cracking model, which takes into account the phenomenon of the simultaneous occurrence of corrosion layer accumulation and corrosion filling paste.
Investigates the parameters and values of expansion coefficients and elastic modulus of steel corrosion, which enables a more rational prediction of concrete surface cracking
Introduces the use of the Gaussian function to describe the non-uniform spatial distribution of corrosion products.

Supplementary cementing materials and other mineral admixtures are being used in increasing amounts in both cement and concrete. Their main technical benefits are that they enhance the workability of fresh concrete and the durability of hardened concrete. Indeed, they affect almost every property of the concrete. Their economic and ecological benefits may be just as significant, and their use can be expected to increase as concrete remains the most common construction material.
Cement and Concrete Mineral Admixtures concentrates mostly on natural pozzolans, fly ashes, ground granulated blast furnace slag, silica fume and limestone powder, namely the most commonly used mineral admixtures. Others such as metakaolin, rice husk ash, expanded clays and shales are also discussed. Their chemical, mineralogical, and physical properties are outlined. The influence of mineral admixtures on the hydration of cementitious systems, and the properties of fresh and hardened concrete in which they are used are emphasized. International standards are reviewed. The basics of concrete mix proportioning with mineral admixtures are outlined. The possibilities of using mineral admixtures as constituents of special concretes such as self-compacting, reactive powder, roller-compacted concretes and special non-portland, low-cost, low-energy and/or low-CO2 cements such as alinite, calcium sulfoaluminate, and belitic cements and alkali-activated binders are also covered.
The book is a comprehensive reference for senior undergraduate and graduate students and researchers in the fields of cement and concrete, and for cement and concrete practitioners.

The challenges facing humanity in the 21st century include climate change, population growth, overconsumption of resources, overproduction of waste and increasing energy demands. For construction practitioners, responding to these challenges means creating a built environment that provides accommodation and infrastructure with better whole-life performance using lower volumes of primary materials, less non-renewable energy, wasting less and causing fewer disturbances to the natural environment. Concrete is ubiquitous in the built environment. It is therefore essential that it is used in the most sustainable way so practitioners must become aware of the range of sustainable concrete solutions available for construction. While sustainable development has been embedded into engineering curricula, it can be difficult for students and academics to be fully aware of the innovations in sustainable construction that are developed by the industry.
Sustainable Concrete Solutions serves as an introduction to and an overview of the latest developments in sustainable concrete construction. It provides useful guidance, with further references, to students, researchers, academics and practitioners of all construction disciplines who are faced with the challenge of designing, specifying and constructing with concrete.

This book presents research on the Boundary Element Method in dynamics of continua. The main emphasis is on the development of the different boundary element formulations for time-dependent problems and the necessary mathematical transformations to produce computer codes that are able to solve scalar, elastic, and poroelastic wave propagation problems. A substantial part of the book also covers the application of the BEM to important engineering dynamic problems.

This book is written for engineering students and practicing engineers who have little knowledge of the boundary element method. Engineers and students have tended to be discouraged by complex mathematics usually employed in explaining this method, which has led to the popularity of the finite element method. This book attempts to redress the balance. It limits the mathematics to one chapter and breaks down the derivation of the formulation into logical steps, allowing the reader to focus on their particular applications. The book features coverage of all important boundary element applications, a step-by-step approach to the formulation and fully documented computer listing providing practical application solutions. It is aimed at research and development engineers and undergraduate and postgraduate students of applied mathematics, numerical computation and advanced mathematics in mechanical, civil and aeronautical departments.

This book deals with the safety assessment of structures and structural components, possibly operating beyond the elastic limits under variable repeated thermo-mechanical loads. Examples of such situations can be found both in mechanical and civil engineering (e.g. transportation technologies, pressure vessels, pipelines, offshore platforms, dams, pavements and buildings in seismic zones). So-called "direct” methods are focused, based on the shakedown theorems and their specialisation to limit theorems. These methods are receiving increased attention for the prediction of structural failure because they provide the information that is essential in practice (e.g. safety factor and collapse mechanisms) by more economical procedures than step-by-step inelastic analysis; also, they only need a minimum of information on the evolution of loads as functions of time. The addressed audience are primarily engineers and scientists active in Structural Engineering and Safety and Reliability Analysis.

Lynda.com - Construction Management Planning and Scheduling
Publisher: Lynda.com
Peresented By: Jim Rogers
Format: mp4
Duration: 01:25
Size: 926 MB
Quality: DVDRip
Schedules are management tools that allow leaders to make informed decisions about activities on a construction site. Although the terms planning and scheduling are often used interchangeably, there is a significant difference between these two activities, and an accurate schedule cannot be developed without first developing a proper plan. Planning activities involve developing the logic of how a project is to be constructed—beginning with the construction documents that define the end product, and then identifying the individual tasks or steps required to arrive at this end result. Scheduling consists of integrating the plan with a calendar or time period, and assigning time durations and resources to each task.
This course identifies the steps needed to develop a proper plan, and demonstrates how that plan is transformed into a construction schedule. Throughout the course, instructor Jim Rogers shares examples of his own successes and failures in the areas of construction planning and scheduling, so as to lend real-world context to the concepts he covers.
Topics include:
-Types of schedules
-Planning versus scheduling
-Work breakdown structure
-Developing a schedule
-Creating a network model
-Assigning durations, costs, and resources
-Identifying the critical path
-Letting the software do the calculations
-Checking and updating the schedule
-Scheduling's impact on productivity
