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).
, cycle. Water molecules continuously move from location to location in this cycle. The water cycle is important to weather and climate and, ultimately, to all life on Earth. The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.
