The pumping nowadays of freshly-mixed concrete is a link of the process chain that one can scarcely
imagine not having. It was not very long ago that it was also the task of concrete technology to spe-
cially design the concrete composition as pumping concrete. Now for the latest stage of concrete
pump technology, pumping concrete is no longer a special concrete. It is a concrete normed by the
concrete technology in a composition as is required for reinforced components of reinforced concrete.

Concrete Basics aims to provide a clear, concise explanation of all aspects of making quality concrete; from the Materials and Properties involved through Planning, Preparation, Finishing and Curing.
Concrete Basics addresses the needs of unskilled and semi-skilled persons undertaking general concreting projects including home and handyman projects.
Concrete Basics also assists owner builders in the supervision of construction.
It aims to develop an understanding of highly technical terms through clear definition accompanied by simple illustrations. A general understanding of these terms will help to facilitate communication within the building industry.
Concrete Basics will help to generate a higher standard of workmanship on-site and facilitate better communication among construction workers, builders,engineers, building surveyors, architects and anyone interested in understanding the processes involved in making quality concrete.

This course book will be limited to presentation of basic principles and process tech-
niques in construction execution. It is intended as an aid and a guide to circumvent some
problems encountered in design and execution, outlining present techniques and materials re-
lated to construction technology for their evaluation and improvement.

MECHANICS OF FLUIDS presents fluid mechanics in a manner that helps students gain both an understanding of, and an ability to analyze the important phenomena encountered by practicing engineers. The authors succeed in this through the use of several pedagogical tools that help students visualize the many difficult-to-understand phenomena of fluid mechanics. Explanations are based on basic physical concepts as well as mathematics which are accessible to undergraduate engineering students.

"Modeling and Control in Vibrational and Structural Dynamics: A Differential Geometric Approach (Chapman & Hall/CRC Applied Mathematics & Nonlinear Science)"
Modeling and Control in Vibrational and Structural Dynamics: A Differential Geometric Approach describes the control behavior of mechanical objects, such as wave equations, plates, and shells. It shows how the differential geometric approach is used when the coefficients of partial differential equations (PDEs) are variable in space (waves/plates), when the PDEs themselves are defined on curved surfaces (shells), and when the systems have quasilinear principal parts.
To make the book self-contained, the author starts with the necessary background on Riemannian geometry. He then describes differential geometric energy methods that are generalizations of the classical energy methods of the 1980s. He illustrates how a basic computational technique can enable multiplier schemes for controls and provide mathematical models for shells in the form of free coordinates. The author also examines the quasilinearity of models for nonlinear materials, the dependence of controllability/stabilization on variable coefficients and equilibria, and the use of curvature theory to check assumptions.
With numerous examples and exercises throughout, this book presents a complete and up-to-date account of many important advances in the modeling and control of vibrational and structural dynamics.

In this unique reference volume, rotary blasthole drilling and surface blasting, as applied in large surface mines, are comprehensively covered. Both new and classic concepts, techniques and methodologies are presented, supported by numerous illustrations and practical data. In 26 chapters, drilling, surface blasting, rock, rock mass, machinery, tools and accessories, compressors and air flushing, computing and practice are many other relevant subjects are treated; the first 16 chapters deal with rotary blasthole drilling, and the 10 next chapters with the concepts, theory and practice of blasting. Moreover, the 14 appendices provide vital technical and commercial data, to further support the reader to design, plan, execute and calculate blasthole drilling operations. This volume is intended for professionals and technicians in mining, exploration, geological and mechanical engineering, who are involved with the design, planning and execution of rotary drilling and blasting operations in surface mines.

Author: David A. Bainbridge | Size: 7,9 MB | Format:PDF | Publisher: Passive Solar Inst | Year: 1981-06 | pages: 104 | ISBN: 0933490038
This book covers the design and construction of simple passive solar water heaters. In my opinion, it is easily the best book ever written on the subject. The book was published in 1981, and is now out of print and difficult to obtain.
Passive Solar Water Heaters:
The water heaters covered in this book make a great DIY solar project. For a few hundred dollars and a weekend of labor, you can build one of these solar water heaters. It will pay back its initial cost in a year or two. One of these water heaters can save about 4000 KWH in a year -- about the same amount of energy that a 1KW PV costing around $10,000 would save!
The book includes:
How to design a passive solar water heater
How to build a passive solar water heater
How to install a passive solar water heater
Examples of many types of designs that would almost any situation
Discussion of potential improvements to the design
