Transport Properties of Concrete covers how to measure the ability of ions and fluids to move through concrete material; and how to use the results to model performance. These transport properties largely determine the durability of concrete and of steel embedded within it; as well as the effectiveness of structures such as landfill containment barriers. The book begins by explaining in detail what transport properties are and how to write computer models for transport processes. Early chapters present and explain computer models written in basic code. Coverage then proceeds to a wide range of tests for the transport properties of concrete; and methods for calculating the values for these properties from the test results using analytical and numerical models. The final chapters then show how the values obtained can be used to predict the durability of reinforced concrete; to model the effect of gas pressure; and to model waste containment structures. A number of practical examples are given; in which the calculations and computer models have been applied to real experimental data. Transport Properties of Concrete provides a comprehensive examination of the subject; and will be of use to all concerned with the durability and effectiveness of concrete structures.Provides a detailed understanding of the various transport mechanisms that take place during testing in concreteShows how to obtain fundamental transport properties

I would say this book is aimed at those who have a pretty good handle on their camera and lenses. Well worth the small price for the kindle edition.0 of 0 people found the following review helpful.

FritzAs a professional photographer; I am asked to do all kinds of work ranging from wedding photos to portraits. I am happy for the work. However; my love is with landscape and nature photography. This is the area where operating my camera is the most fun and where my heart resides. I am drawn; therefore; to a well written; well produced book on the subject of landscape and nature photography. This is one such book.Although her book is about nature and landscape photography; Brenda Tharp discusses light a great deal in her book; "Expressive Nature Photography: Design; Composition; and Color in Outdoor Imagery." And well she should because without a firm understanding of light and its various natures; it is difficult to impossible to expect quality results in photography.Tharp is not just focusing (no pun intended) on mundane but necessary things such as aperture or shutter speeds. Yes; those are covered. She even includes the recorded focal length; aperture and shutter speed for each of the numerous example photos in her book--a most helpful addition to the book itself. Still; what drives Tharp and what should drive each of us as photographers (amateur; semi-pro and pro) is the quality and type of light. Is it top-down (direct noon-type light;) front light; sidelight; backlight or bounce light? What color is the light? Yes light; even sunlight; can exhibit different colors at different times and seasons. Each type and color impacts the nature of light seen on the subject and therefore the resulting photograph. The same object is not the same photograph under different lighting conditions.Tharp provides clarity and direction concerning light; even going so far as to dispel some common misconceptions about the histogram. However; she is firm in pointing out that; "There is no such thing as bad light; there is only light."I agree--especially when it comes to digital photography. Some of my best and most cherished digital images were taken in horrid light. Sometimes the light was so poor (low quality or at a horrid angle) that I assumed that the photo would be a complete waste of time--that is until I post processed the image and saw the inadvertent magic that the light had created.I do a major disservice if I fail to mention something that Brenda Tharp states right at the beginning of her book. ldquo;This book is about making your best photographs of nature. Itrsquo;s also about being present in the moment when making a picture.rdquo; (Page 13.)This is so very important. If our minds are elsewhere; our photos will show our distraction. Tharp even recommends that; at times; we should leave our cameras behind and simply soak in the elements with our eyes. This is equally important because; while the camera is a wonderful tool; it is also a distraction. If you are photographing something you are not really looking at it. You are instead focused on the process of image taking.My father used to have a saying. ldquo;Do as I say not as I do.rdquo; Tharp; on the other hand is saying something very different. ldquo;Listen to what I say; but look at what I have done.rdquo; Her text and her photos do a wonderful job of complementing one another.To be honest; I own a ton of photography books. Most; except for a precious few; are bound for the recycling bin. ldquo;Expressive Nature Photography: Design; Composition; and Color in Outdoor Imageryrdquo; is not one of them. Brenda Tharp has done a marvelous job with creating her book. That; coupled with a quality printing job on decent paper stock; makes this a book that I not only read cover-to-cover; but will also keep permanently as a reference book.
