I'm thinking of making a science forum , so what are the steps I should follow for doing this !?
I've heard that you must pay money for this , I've also heard that you can steal the design of a website and change text .. !?
Well , after surfing the net , there are several free making websites such as yola - - But I think that this must be learnt so it must take time , not minutes !!!

Towards the Eurocodes era
The Eurocodes are built on best European practice, expertise and research achievements. They provide for highest technical quality of construction design. Furthermore, the Eurocodes will create job opportunities by giving engineers, contractors, designers and product manufacturers the freedom to provide services in any Member State throughout Europe. The competition in cross-border provision of construction products and services will contribute to lower costs, raising quality and favouring technological innovation.
The Workshop “Eurocodes: Background and applications” marks the achievement of a key milestone in the European standardisation for construction: all Eurocodes parts being published by CEN and ready for implementation and use in the Member States.
It is also a major European training event on the Eurocodes. The workshop is organized by the European Commission with the support of CEN and Member States. It aims to transfer knowledge and state-of-the-art training material and information from the Eurocodes writers to representatives of key institutions, Industry and technical associations involved in training on

Contents:
1. EN 927-1:1996 Paints and varnishes - Coating materials and coating systems for exterior wood - Part 1: Classification and selection
This European Standard specifies a system for the classification of coating systems for exterior wood surfaces by categories of end use, appearance and exposure conditions. It is applicable to all coating materials and coating systems intended for decoration and protection of exterior wood surfaces including those which contain biologically protective ingredients for the protection of coatings and at their interface with the wood surface (film preservation).
2. EN 927-2:2006 Paints and varnishes - Coating materials and coating systems for exterior wood - Part 2: Performance specification
This part of EN 927 addresses performance criteria for coating systems on exterior wood. Performance requirements are specified according to the categories of ''end use'' and ''exposure conditions'' (defined in EN 927-1) in terms of the results of natural weathering performance testing carried out in accordance with EN 927-3. A mandatory water permeability test in accordance with EN 927-5 is also specified. Additional optional tests are identified which may be used by suppliers to provide voluntary additional information, to a standardized format, on aspects of performance relevant to specific building components such as windows.
3. EN 927-3:2006 Paints and varnishes - Coating materials and coating systems for exterior wood - Part 3: Natural weathering test
This part of EN 927 specifies a natural weathering test for exterior wood coating systems mainly intended for decoration and protection of planed and sawn wood.
The test provides a means of evaluating the performance of a wood coating system during outdoor exposure. It forms the basis for the performance specification in accordance with EN 927-2.

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.

Contents of the rar-file:
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.
