When professor Naaman first contacted me and asked me to post a review of his book on the ferrocement website I was intrigued . I went to the publisher’s website and read the existing reviews.
Phrases such as " the most comprehensive and authoritative treatment of the subject " and "indispensable book for engineers, architects, researchers, students and contractors interested in ferrocement" lead to a feeling of doubt that any one book could be this informative.
After reading the book I find that my doubts were groundless.This book is indeed the finest and most comprehensive book on the subject that I know of. Professor Naaman has pulled together his 25+ years of experience and research in the ferrocement field and come up with a textbook of ferrocement. This book will most likely become the standard textbook for the teaching field when it comes to ferrocement.
This book is not a how-to type of book. There are books that have been written in the past that cover the basics of the how-to part of working with ferrocement. To give you an idea of what is contained in the book I will give you the chapter headings.
Chapter 1 - Introduction to Ferrocement
Chapter 2 - Mechanical Properties Of Ferrocement as Observed From Tests
Chapter 3 - Modeling the Response of Ferrocement and Other Brittle Matrix Composites With Continuous Fibers
Chapter 4 - Analysis and Design of Ferrocement in Bending
Chapter 5 - Practical Design Guidelines
Chapter 6 - Construction – Fabrication of Ferrocement
Chapter 7 - Testing for Reinforcement and Composite Properties
Chapter 8 - Cost Estimates of Typical Ferrocement Composites
Chapter 9 - Ferrocement in Housing and Related Applications
Chapter 10 - Advanced Materials and Concepts
Chapter 11 - Prospects for Ferrocement Materials, Applications, and Technology
Professor Naaman has set the standard by which future books on ferrocement will be judged.

1. BS 1139-1.2:1990 Metal scaffolding. Tubes. Specification for aluminium tube;
2. BS 1139-2.1:1991, EN 74:1988 Metal scaffolding. Couplers. Specification for steel couplers, loose spigots and base-plates for use in working scaffolds and falsework made of steel tubes;
This British Standard specifies the requirements for materials and design, and test procedures and methods, for couplers, loose spigots and base-plates used for connecting steel tubes of 48.3 mm outside diameter and of at least 3.2 mm nominal wall thickness at a minimum in the construction of working scaffolds and falsework required for the construction, maintenance, repair and demolition of buildings and structures.
When no alteration has been made to the design, material or surface treatment of a type of coupler which has been approved as a prototype according to this British Standard, the assessment of subsequent production is made by comparison with the requirements given in this standard.
Some significant points about this Section of BS 1139 to which attention is drawn are the following.
a) Other scaffold couplers and fittings commonly in use in the UK are dealt with in BS 1139-2.2.
b) For right-angle and friction type sleeve couplers there are now two load classes.
c) The minimum permissible base-plate area is now a little smaller.
d) Load bearing parallel couplers are now specified.
e) There is an increased minimum yield strength requirement on all coupler fasteners (typically bolts) together with a restricted torque tightening/wedge range.
f) The philosophy of testing has been changed to verify an individual coupler design and facilitate on-going quality assurance.
g) Additional information is required to be marked on all products.
h) There is limited information on hexagon sizes. The United Kingdom scaffolding industry generally requires hexagons to be between 20.3 mm and 20.8 mm across flats.
3. BS 1139-2.2:2009 Metal scaffolding. Couplers. Aluminium couplers and special couplers in steel. Requirements and test methods;
4. BS 1139-3:1994 Metal scaffolding. Specification for prefabricated mobile access and working towers;
5. BS 1139-4:1982 Metal scaffolding. Specification for prefabricated steel splitheads and trestles;
6. BS 1139-6:2005 Metal scaffolding. Specification for prefabricated tower scaffolds outside the scope of BS EN 1004, but utilizing components from such systemss;

BS 1427 describes methods for the analysis of industrial and other waters. These methods can be undertaken outside of the chemical laboratory, for example on-site tests. This guide is for testing when the purpose of the test is to characterize the water under test for quality or process control purposes. The test methods are simple procedures for use by a trained analyst or by an individual that has had appropriate training.
Since 1993, many industrial laboratories have been shut down and the use of on-site methods increased significantly. Non-analysts using proprietary test-kits carry out a very significant proportion of these tests.
This revision of BS 1427 contains updates to specific methods since the previous standard and provides guidance on the use of the much wider range of available commercial test-kits. Since 1993, the range, type and quality of commercial test-kits/apparatus have improved. The improvements include significant benefits in terms of increased reliability and ease of use for on site testing. The use of pre-packaged chemicals and reagents has also reduced health and safety risks associated with handling chemicals and enhanced the simplicity of testing.
Most of the methods described in this standard apply to use on clean or lightly polluted waters which might have undergone treatment or been modified for industrial use.
The types of waters that are normally tested include:
a) Boiler waters
b) Cooling waters
c) Waters from hot water systems
d) Waters from air conditioning systems
e) Waters from industrial air washing systems
f) Potable waters
g) Ground waters
h) Surface waters
i) Process waters
j) Swimming pool waters.
Who should use BS 1427?
Water industry samplers and analysts
Environmental and water treatment consultants

Ark Hotel Construction time lapse building 15 storeys in 2 days
Size: 0.01 MB
This video shows an spectacular building erection in just 2 days!
The main issue of this post is open a discussion about the importance and efficiency of planning! full and complete planning from design, through manufacturing prior pre-assembly, logistics and erection.
Of course, this is not a building built in 48 hours, but certainly had more than a year of planning and work.

I would like to check with you is there any particular reason that you do not allow people to edit their post?
I uploaded my very first file to contribute to the community, but from time to time I will receive feedback from user that there are something missing from the installation package or the link is dead after some time.
By having the flexibility to update the post we can easily update and consolidate everything rather than keep giving new post with new mirrors which makes the topic looks long and people have problem identifying which link is the correct one.
Thank you
And I seem not able to PM any Mod to ask them to change / update my links... :(
