in 2010 to nearly 1180 BCM in 2050 with home and commercial water intake anticipated to boom nearly 2.five times. The use of pre-pressured concrete may be very uncommon for creation of water preserving systems because it calls for professional labour, heavy machineries & eager supervision. But this creation may be most cost-efficient for water preserving systems of huge capacity. The overdue Eugene Freyssinet, a outstanding French engineer commonly seemed as the daddy of pre-pressured concrete, changed into the primary to apprehend the want to apply steels of excessive fine and power, pressured to fantastically excessive levels, so as to triumph over the unfavourable outcomes of concrete creep and shrinkage. In the early 1950s, following strategies used efficiently in Europe for some of years, numerous round pre-pressured concrete tanks have been built withinside the United States the use of post-tensioned excessive tensile-power cord tendons embedded withinside the tank partitions. The posttensioned tendons in maximum early “tendon tanks” have been grouted with a Portland cement-water aggregate after stressing to assist shield them towards corrosion and to bond the tendons to the concrete tank partitions. Others have been unbounded- paper-wrapped person cord or strand tendons that relied on a grease coating and the castin-region concrete for his or her corrosion protection. Later, the usage of unbounded tendons with corrosion-inhibiting grease coatings and plastic sheaths have become extra not unusualplace. Most of the early tendon tanks built with inside the U.S. observed the not unusual place European exercise of vertically pre- stressing the tank partitions to dispose of or manage horizontal cracking. This crack manage helped save you leakage of the contents and corrosion of the pre-stressing metallic. The pre-stressing of concrete has numerous blessings in comparison to conventional bolstered concrete (RC) with out pre-stressing.
treatment plant like clariflocculator, aeration tank, disinfection tank etc. are composed in RCC. Pre-stressed concrete is not economical for small structures. But this construction can be efficient for water treatment plant. The pre-stressed steel strands distribute loads uniformly around the tank circumference efficiently. In pre-stressed concrete, compressive stresses are applied to the concrete prior to loading. The entire cross section is essentially in compression under service loads, which takes advantage of concrete’s considerable compressive strength but minimal tensile strength. Since concrete deforms under sustained loads (creep), pre-stressed concrete was not practical until the advent of high strength pre-stressing bars and strands. In case of RCC tanks, moisture and temperature differential may cause bend and crack of concrete walls which can be avoided by using pre-stressed concrete. The aim of study is to design the components of water treatment plants using pre-stressed concrete and compare with the components of R.C.C. water treatment plant. The components are designed for the same storage capacity for both RCC & PSC. Design of components of RCC water treatment plant is compared with the design of components of pre-stressed water treatment plant based on various important parameters. The modeling and analysis part of the water tank design will be carried out by using STAAD PRO. This study is concerned principally with recommendations for pre-stressed concrete structures for noncorrosive liquid storage.
Key Words: Rigid base components of water treatment plant, Reinforced Cement Concrete Design, Pre-stressed Concrete Design, Analysis, minimum total cost, tank capacity.
