Products used in water treatment plants and water supply structures
By Nặc danh - tháng 6 08, 2011
Waste water/Sewage treatment plant and water supply structures are those structure built to contain waste and potable water, properly designed to withstand internal, external loads and aggressive environmental exposures both physical and chemical in order to prolong service-life.Reinforced concrete structures as part of Waste Water/Sewage Treatment Plant and Water Supply structure are exposed to severe physical and chemical exposure such as impact, vibration, sulphate and chloride exposure. In tropical climates, the combination of the above deleterious effects may cause severe defects in concrete structure thus limiting the life expectancy of the structure.
In order to delay these detrimental effects, high durable, chloride and sulphate resistant concrete become a necessity in constructing Waste water / Sewage treatment plant structure. The use of silica fume such as Sikacrete PP1 combined with Sikament, or Sika Viscocrete range, high water reducing with retarding effect admixture, then become increasingly popular to produce a durable concrete (low permeability and high sulphate/chloride resistant concrete).
Proper mix design elaboration taking into account project requirements, then adherence to good concrete practices (concrete placing, vibration, concrete curing) shall ensure the concrete work to be of best quality.
With the following product proposal/method statement of application, Sika is giving full package technical solutions including concrete admixtures, concrete work supporting products (formwork release agents, curing compounds), external and internal coating solution for protective and waterproofing purposes, joints sealing…
