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 within the water cycle. â¢ Identify the three states of water and how water transitions between them. BACKGROUND AND TEXT OVERVIEW INTRODUCTION The Water Cycle is the endless movement of water around the planet. Earthâs natural systems are constantly moving and using water. As a liquid, gas or solid, powered by the sun and the forceofgravity,watertravels over, under and above the sur-face of the Earth in an incredible journey called the water cycle.
