1.3-POLYMER FIBER REINFORCED CONCRETE:-Civil structures made of steel reinforced concrete normally suffer from corrosion of the steel by the salt, which results in the failure of those structures. Constant maintenance and repairing is needed to enhance the life cycle of those civil structures.
The water cycle, air pressure, and weather are actually very closely related. The water cycle is the process of water being drawn up from the ground into the sky, where air pressure is lower. (Pressure gets lower as altitude increases, since there is less air available to press down).
The water cycle, is a naturally occurring cycle which purifies and renews the Earth's water. Usually starting with evaporation, the water is turned into steam and lifted to fo â¦ rm clouds which then come back down in the from of precipitation. Then the precipitation runs off surfaces into drainage basins, underground water sources or large bodies of water.
