When is concrete used without metal reinforcement bars?
Concrete are used without reinforcement bars on concrete roads.
What stronger brick or cement?
http://simscience.org/cracks/advanced/concrete2.html A common mistake people make is to use the words cement and concrete interchangably. It is important to remember that cement is only a component of concrete and concrete is the structural material. The cement used in concrete is not used as a building material because it would be too expensive and not as strong as concrete. So when you see a parking garage, a driveway, a sidewalk or a road remember it is made of concrete, not cement. And, by the way, that funny looking truck is a concrete mixer, not a cement mixer! But, if cement is not concrete, then what is it? Cement is a general name for a material that binds other materials together. Yes, it is another name for glue. There are many materials which we would classify as cements and they are usually identified with certain uses, and can produce different types of "concrete". The type of cement used to make the riding surface of some of our roads (blacktop!) is called asphalt cement. It is a petroleum bi-product, and it binds rock into the road material we call asphaltic concrete.
Difference between the civil engineering project and the building construction project?
Building is a structure and civil in water, sewer, storm drains as well as roads and bridges.
How much weight can a 4 inch concrete road carry?
I'm sure it depends upon how well you prepare the subsurface. A good foot of hardpack, quality dirt with another six inches to a foot of roadbase underneath four inches of properly laid concrete can offer some major load bearing qualities. If I were you, I would research how the Autobahn and similar roads are constructed. They are built very differently from most highways and Interstates in the United States.
What is used to pave roads?
asphalt
Why are concrete roads laid in sections with a pitch between them?
Because then it has room for moving and shrinking, growing etc Concrete roads and pavements are laid in sections and a all gap is left between each sections. This is filled either tarmac or rubber compound
Why concrete roads are laid in section with pitch between them?
Concrete, whether in a road or a building expands (gets longer) in hot weather and contracts (gets shorter) in cold weather. So the builders install an expansion strip every so many feet to allow the concrete to make these small but significant changes in length. If this were not done, the concrete, when warm, would expand, and having nowhere to go, would go up (roads) or out (buildings), thus ruining the road or building. These expansion joints are filled with pitch, tar, or mastic - they call it different things in different parts of the country - to keep out water. Water would freeze, and cause the same problems.
Why concrete roads snd floors always made in sections?
To allow for expansion. if it's not done in sections, slabs will crack and chip off in undetermined locations
Why do roads have the gaps between the large pieces of concrete?
They are expansion gaps that allow for the expansion and contraction of the concrete.
Why do concrete roads have gaps between large pieces of concrete?
As the weather varies the concrete expands and contracts. If there were no gaps the concrete would buckle and crack.
What is the property of matter where it changes volume when it changes temperature?
The property of solids in which they enlarge when warmed is thermal expansion. The opposite, shrinking when cooled, is thermal contraction. This property greatly effects how bridges, sidewalks, and concrete roads are made. They all have "expansion gaps," gaps between sections that allow the sections to expand in the heat of summer. Without those, the concrete would break and the bridges would warp and bend.
Are there concrete roads in Washington state?
No the roads are made out of asphalt.
