Factors Affecting DurabilityDiagnosing The ProblemCorrosion ProtectionAbrasion,Chemical Attack and Freeze-Thaw ProtectionWater TanksWastewater TanksConclusionAll concrete deteriorates over time.The rate at which concrete deteriorates is a function of two factors the quality of the concrete and the environment to which the concrete is subjected.The quality of concrete refers to the properties incorporated into the original concrete mix design such as water/cement ratio,cement type,size and hardness of the aggregate and air entrainment.Quality is also dependent on the construction practicesSee more on wwdmagDesign of Water Tank - nitrkl.acthe reservoirs or tanks is about the same irrespective of the chemical nature of the product.All tanks are designed as crack free structures to eliminate any leakage.Water or raw petroleum retaining slab and walls can be of reinforced concrete with adequate cover to the reinforcement. How are industrial wastes collected in concrete tanks?How are industrial wastes collected in concrete tanks?Industrial wastes can also be collected and processed in concrete tanks with few exceptions.The petroleum product such as petrol,diesel oil,etc.are likely to leak through the concrete walls,therefore such tanks need special membranes to prevent leakage.Design of Water Tank What kind of cement is used in potable water tanks?What kind of cement is used in potable water tanks?To protect concrete in potable water tanks,polymer-modified cementitious coatings have been used with much success.A polymer-modified cementitious coating can provide an extremely dense protective layer on the surface of concrete while at the same time providing a degree of flexibility.Protecting Concrete Tanks in Water and Wastewater Treatment Plants
