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 main source of energy in the water cycle is the sun/Solar radiation (sunlight). the source of energy that drives the water cycle is the sun because since the sun's heat makes the water evaporate which will led to the whole process of the water cycle and the process will keep on repeating.
