Excerpt from A Study of the Effect of Moisture Content Upon the Expansion and Contraction of Plain and Reinforced Concrete Aside from the action of direct load, deformations are produced in concrete by changes in temperature and in moisture content. With reference to temperature changes in reinforced concrete, it is well known that, regardless of differences in the mixture, concrete has practically the same coefficient of expansion as steel, so that the two materials contract or expand together. Moisture content, on the other hand, has the undesirable property of affecting concrete alone. Con crete, like wood, clay, and some other materials, expands when it absorbs moisture and contracts when it is dried; steel has no such action. After the concrete is poured the steel remains unchanged with changes in moisture conditions, while concrete ordinarily shrinks a considerable amount. Aside from the stresses set. Up in steel and concrete by the shrinkage of the latter, the resulting formation of cracks large or small will produce a condition which may be favorable to the corrosion of the steel or the disintegration of the concrete after repeated changes from dry to wet condition.

Excerpt from Reinforced Concrete, Theory and Practice Much has been written upon the subject of reinforced concrete, and the design of structures in this material no doubt still affords opportunity for invention and improvement. New systems, new bars, new details of various kinds are constantly being patented in many countries, but the leading features and ideas remain the same. Generally speaking, one may say that there are as many systems as there are specialists, each naturally insisting upon the superiority of his own favourite ideas. The Author had occasion to see reinforced concrete constructions designed and executed for many years, and has closely followed its development. His principal object in writing this book was not to put forward any particular method of construction, but to collect in a concise form what seemed to him best of the many formulae and systems used in various countries, and to deal with the subject in such a manner as to be intelligible to average students of architecture who have not been required to devote that amount of study to the theory of construction which is demanded of the young engineer. At the same time, it is hoped that the present volume may be useful also to the latter. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Investigation of the Effect of Heat Upon, the Crushing Strength and Elastic, Properties of Concrete The concretes used have included trap, limestone and cinder, and were usually 1-2-4 or 1-2 5 mixtures. The reports of numer ous tests of this character were examined and in most instances the concrete stood the heat and subsequent loading well, but the results were general and referred to the quality or resistance of a particular construction rather than to specific data regarding the concrete itself. Large numbers of tests of compressive strength and elastic properties have been made upon concrete of various composition and after different preliminary treatments, but no records were found in which the concrete was heated prior to testing.

Excerpt from Experimental Researches on Reinforced Concrete It is in the contin'uation of such researches and their full discussion that the future development of reinforced con' crete lies. From such investigations the designing engineer will be able to judge for himself the use he can make of this material in the vast field of modern engineering construe tion. This is well understood by engineers the world around, and very recently the Swiss Commission on Reinforced Con crete has decided to undertake the investigation of the sub ject, at a cost of about on the lines practically laid down by Considere's researches.

Moisture control is fundamental to the proper functioning of any building. Controlling moisture is important to protect occupants from adverse health effects and to protect the building, its mechanical systems and its contents from physical or chemical damage. Yet, moisture problems are so common in buildings, many people consider them inevitable. Excessive moisture accumulation plagues buildings throughout the United States, from tropical Hawaii to arctic Alaska and from the hot, humid Gulf Coast to the hot, dry Sonoran Desert. Between 1994 and 1998, the U.S. Environmental Protection Agency (EPA) Building Assessment Survey and Evaluation (BASE) study collected information about the indoor air quality of 100 randomly selected public and private office buildings in the 10 U.S. climatic regions.

The psychology classic—a detailed study of scientific theories of human nature and the possible ways in which human behavior can be predicted and controlled—from one of the most influential behaviorists of the twentieth century and the author of Walden Two. “This is an important book, exceptionally well written, and logically consistent with the basic premise of the unitary nature of science. Many students of society and culture would take violent issue with most of the things that Skinner has to say, but even those who disagree most will find this a stimulating book.” —Samuel M. Strong, The American Journal of Sociology “This is a remarkable book—remarkable in that it presents a strong, consistent, and all but exhaustive case for a natural science of human behavior…It ought to be…valuable for those whose preferences lie with, as well as those whose preferences stand against, a behavioristic approach to human activity.” —Harry Prosch, Ethics
