Kêmkirina Avê Çimento Çi ye?

YEK cement water reducer is a chemical admixture that decreases the amount of water used in concrete. Ev kêmbûna avê dihêle ku beton bi rêjeyek kêmtir hîdrote bike, giving it better strength and durability.

Kêmkirina avê kêm-range, also known as normal water reducers or regular plasticizers, typically lower the amount of water in a mix by 5 ber 10%. These water reducers are often used in everyday concrete applications such as driveways, peyarêkan, û dîwarên jêrzemînê.

Kêmkerên avê yên navîn, also called plasticizers or intermediate plasticizers, typically lower the amount of concrete that needs to be mixed by 15 ber 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 ber 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.
