Civil engineering is the oldest form of engineering.  It is the design and construction of public structures and facilities.  Civil Engineers typically design bridges, dams, water treatment plants, highways, and power stations.  A civil engineer will analize the forces that will be present in the project area as well as the types of soil, water shed etc.  They will use what they gather to design a system that will both complete the task at hand but also complement the environment around it.  With what they find they use math and complex analysis to see if their designs are safe.

A civil engineer is the one who builds fixed physical structures, like buildings and houses, bridges, highways and roads, etc.\n\nThere a lot of good material in the links below.

You should show how ice expands and can damage roads and concrete... very stiff materials.\nCheck out the links\n\nOh yes and don't forget about wear and tear cars and other vehicles can cause... I am not sure how much time you have for your science fair project... typical road wear studies can last for years.

Well, lets see ... there's plastic, steel, and nylon for sure.  \n\nAnd possibly ...adhesives, polystyrene, paint, glass (this one's a little iffy because it does occur in nature, albeit infrequently)

check out the site of Bureau of Indian Standards (BIS). It has catalogued references of specifications of various materials and standards.

there are many uses for aerospace engineers

Look up Vector Mechanics for Engineers and Scientists.  This deals with basic Newtonian physics as applied to static structures.\n\nBone up on chemistry.  It is easy to forget your chemistry, and as far as I know you will be required to take a few semesters of basic Chem, even if you are not planning on being a Chem Eng.\n\nDo not lose your Maths either!  Grab a pre-calc or a calculus book and keep practicing.

If requested at the time of purchase most suppliers and all mills can provide documentation related to material composition and mechanical properties of pipe and fittings. All of these items are manufactured to meet API, ANSI, ASTM and other international recognized standards. All such items are also required to be clearly marked so items manufactured of different materials are not confused in the process or shipping and delivery.

I work with epoxy composites. Epoxys have decent thermal conductivity and are strong, there are also a million different types of epoxys out there, so i'm sure theres a formula that would work for you. Good Luck

YOUR DEALING WITH SALT WATER SO A DERIVITIVE WOULD BE ANTI AGRESSION TO THIS  SOME CONCRETE COMPANIES MAY HAVE THIS TRUE ANSWER\nANTI CORROSIVE PROTECTANT \nSEE IN FLORIDA WE USED A ALUMINUM BASED METAL BUT CHECK WITH THE CONCRETE MANUFACTURES IN YOUR AREA

Never trust materials science majors ...\n\n1. NaCl (s) --> Na+ (aq) + Cl- (aq)\n2. Ca (s) + 2H2O (l) --> Ca(OH)2 (s) + H2 (g)\n3. Ca(OH)2 (s) --> H2O (g) + CaO (s)

here is something:\nwww.mmsconferencing.com/nanoc/\npdf/finalcircular.pdf\nand here is something else:\nNano-concrete is an example of a non-exotic material made better through nanotechnology and coming to market.  The ability to see and analyze material at the nano-scale means that concrete can now be  manufactured in such a way as to enable 3-inch thick highway bridge decks.  There are 150,000 obsolete bridges in the U.S. alone.  Nano-concrete can enable them to be rebuilt more cheaply and faster, and to be stronger and longer lasting.  The key impediment will be standard aversion to new ideas in the construction industry.\nanyway, google it for more info

Here's what the US Dept of Labor has to say:\n\n"Civil engineers design and supervise the construction of roads, buildings, airports, tunnels, dams, bridges, and water supply and sewage systems. They must consider many factors in the design process, from the construction costs and expected lifetime of a project to government regulations and potential environmental hazards such as earthquakes. Civil engineering, considered one of the oldest engineering disciplines, encompasses many specialties. The major specialties are structural, water resources, construction, environmental, transportation, and geotechnical engineering. Many civil engineers hold supervisory or administrative positions, from supervisor of a construction site to city engineer. Others may work in design, construction, research, and teaching."\n\nHope that helps!
