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, also known as the hydrologic cycle, is the process by which water moves from place to place above, on, and below the Earth's surface.This is the process by which water moves around the Earth to different places.lants use water to help make energy, and they also lose some water to the surrounding air through the process called transpiration. Transpiration is a plant losing water through its leaves. It is just like we humans lose water to the air through our breath.
