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).
Condensation and the Water Cycle. The water cycle is essentially the path that water takes as it moves from the rivers, up to the clouds and back down to the Earth as rain. Water is always evaporating from streams, lakes and the ocean. As it rises into the atmosphere, it cools and condenses in the form of clouds.
