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).
Water Cycle. Water rains down to the earth on stormy days. It gets soaked up into the ground. Water movement is part of the water cycle. The water cycle is important to all living things on the earth! There are other cycles in your life. Your daily routine is a cycle. You wake up. You go to school. You ride the bus home. You go to soccer practice. You eat dinner. You go to bed. These events are part of a cycle. This cycle repeats itself every weekday. The water cycle is also a set of repeated events that happen over and over again. Evaporation, condensation, precipitation, and collection are the repeated events in the water cycle.
