എന്താണ് സിമൻ്റ് വാട്ടർ റിഡ്യൂസർ?

എ cement water reducer is a chemical admixture that decreases the amount of water used in concrete. ജലത്തിൻ്റെ ഈ കുറവ് കോൺക്രീറ്റിനെ കുറഞ്ഞ നിരക്കിൽ ഹൈഡ്രേറ്റ് ചെയ്യാൻ അനുവദിക്കുന്നു, giving it better strength and durability.

ലോ-റേഞ്ച് വാട്ടർ റിഡ്യൂസറുകൾ, also known as normal water reducers or regular plasticizers, typically lower the amount of water in a mix by 5 വരെ 10%. These water reducers are often used in everyday concrete applications such as driveways, നടപ്പാതകൾ, ബേസ്മെൻറ് ഭിത്തികളും.

മിഡ്-റേഞ്ച് വാട്ടർ റിഡ്യൂസറുകൾ, also called plasticizers or intermediate plasticizers, typically lower the amount of concrete that needs to be mixed by 15 വരെ 20%. These admixtures are often used in concrete for flatwork, such as driveways and sidewalks, because they reduce the water needed to produce a good-quality surface.

High-range water reducers, also known to be superplasticizers or high range admixtures, are synthetic water-soluble organic compounds that decrease the amount of water in concrete by 25 വരെ 30%. This results in a higher fluidity of the concrete, allowing it to flow better and provide more flexibility for placements.

These admixtures are usually added to the concrete mixture at a low dosage rate, although some high-range admixtures require a higher dose for optimal performance.

Most of these admixtures have no effect on the hydration of the cement, but some – like polycarboxylates – may increase air entrainment. This will vary depending on the chemistry of the admixture and its dosage rate. It is important to select the proper admixture for the application.
