When it comes to the use of acids in various industries, especially in the construction sector, two names often come up: tartaric acid and citric acid. Both are organic acids with distinct properties and applications, including their roles as mortar retarders.
But are they the same?
Understanding Tartaric Acid and Citric Acid
What is Tartaric Acid?
Tartaric acid is a naturally occurring organic acid found in various plants, particularly grapes, bananas, and tamarinds. It is commonly used in the food industry as a stabilizer and additive, and you might know it as the main component of cream of tartar. Tartaric acid plays a crucial role in the wine industry, impacting the taste, color, and pH level of wine.
What is Citric Acid?
Citric acid is another organic acid, predominantly found in citrus fruits like lemons, limes, and oranges. This tricarboxylic acid is integral to the citric acid cycle (Krebs cycle) in cellular metabolism. Citric acid is commonly used in food and beverage industries as a flavoring and preservative due to its tangy taste and ability to balance pH levels. It’s also widely used in cleaning products and cosmetics for its chelating properties.
Applications as Mortar Retarders
Tartaric acid can be added to mortar and concrete mixes to slow down the setting time. This property is particularly useful in hot weather conditions or large construction projects where extended workability is required. By delaying the hydration process, tartaric acid helps in achieving better finishes and reducing cracks.
Similarly, citric acid is used as a retarder in the construction industry. Its ability to control the setting time of cementitious mixtures makes it valuable for applications such as flooring, tiles, and concrete repair. Citric acid’s effectiveness as a retarder is attributed to its impact on the hydration of cement particles, thus providing the necessary time for proper placement and finishing.
While both tartaric acid and citric acid serve as effective retarders in mortar applications, they are not the same and exhibit different chemical properties. Tartaric acid is more commonly associated with the food and wine industries, whereas citric acid, besides being a popular food additive, is extensively used in cleaning products and industrial applications. Their selection as mortar retarders depends on specific project requirements and environmental conditions.
