what is the effect of concrete on the environment?

If people pave their whole back yards, water has no where to drain off to.  It wouldn't be able to be absorbed into the grass.  Also, I think the sun reflecting off the concrete is heating up our cities a degree or two.

The paint applied to the concrete is aqua (blue-green).  The paint prevents  the lime in the concrete from dissolving in the water.  The color is aesthetically pleasing to the eye.

Primarily toxic waste, including environmental pollution. industrial accidents, accidents in transportation, and waste hear pollution.

concrete conducts more heat from the ground below and prevents dew from condensing on it.

i think u mean concrete,right?\nprbbly...something stronger than u imagine,there are few types of concrete...u should check out some construction related info's.sry i don't know any link right now,but maybe thee will be sstudiedwho can give u one.i did studyed something about it in the university,but i forgot the exact thing!

Naturally.  As long as pollution continues, the world logically will be more polluted every day.  The population grows exponentially, most of that population acquires a car, resulting in air and noise pollution.  The many natural disasters to recently grip the world (the Indian Ocean tsunami, Hurricane Katrina, etc.) massively increase pollution by rupturing and spreading sewage pipes.  As more fuels are burned, acid rain is made, heavily polluting the water, along with runoff from more construction sites and pollutants from factories.  This in turn affects groundwater, polluting the soil.  As all of these causes increase with the population, so will pollution.

Many things, try lookin it up in the internet, type ur question on yahoo search, and many things will come up for u. good luck with ur info, the real spelling is environment

Embedded aluminum roof flashing, aluminum water stops, aluminum electrical conduit, introduced aluminum powder (sometimes used to foam concrete), or embedded structural aluminum shapes may all corrode in concrete or mortar. In all cases, a reaction that forms aluminum hydroxide and hydrogen gas occurs, and may cause expansion and cracking of the concrete or mortar. The common use of calcium chloride (or other alkali compounds), and dampness of the concrete increases the reaction rate. Usually, coating the aluminum with bituminous paint, impregnated paper or felt, plastic, or an alkali-resistant coating will prevent or sharply reduce the corrosion.

Surfactants are used to prevent the surface tension forming the bubbles.  However, carefull experimentation must be done to make sure they do not have a negative effect on the strength of the concrete.

Check under Science and Mathematics.\n\nthere is an Environment category.

Environment pollution is pollution of water, air, soil, noise, light , visual and radio active .\n\n Pollution is the release of chemical, physical, biological or radioactive contaminants to the environment. Principal forms of pollution include: air , water....\nAir pollution is a broad term applied to any chemical, physical (e.g. particulate matter), or biological agent that modifies the natural characteristics of the atmosphere. The atmosphere is a complex, dynamic natural system that is essential to support life on planet earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the earth's ecosystems.\n\nWorldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease. Setting of air quality standards, such as the U.S. Clean Air Act, has begun to improve air quality for some pollutants. While major stationary sources are often identified with air pollution, the greatest source of emissions are actually mobile sources, principally the automobile. There are many available air pollution control technologies and urban planning strategies available to reduce air pollution; however, worldwide costs of addressing this issue are high. The most immediately available method of improving air quality is adoption of greater use of ethanol fuel (and other bio fuels) and increased reliance upon hybrid vehicle technology.\n\nYou can check out more your self.\nAir pollution :

wat yah mean by concrete by d way!?!?

I believe the classic way of showing the effects of acid rain is to use lime stone corrosion. Test the possibilities using a piece of limestone (chalk or similar), three different petrie dishes, on one use ordinary distilled water, the next with an alkaline solution the the third with acid and note the effects. The latter should start to bubble hence showing a reaction between the two. This has a huge knock on effect with buildings, cliffs, statues, etc as they are worn away by rain which has become acidic.

Depending on location, local building code and sizemic zone.\n By deffinition, the amount of conctete that is measured from the center of the reinforcing steel to the edge of concrete, "cover" references covering the reinforcing.
