Citric Acid technical grade/Cementing&Concrete Retarder for construction industry

Citric acid is a kind of strong organic acids and dissociation degree is bigger, after
dissociation of ion of slurry with a retarding effect and dispersion effect, but the effect of
citric acid not only that. Indoor experimental results show that citrate influence the development
of cement strength; Under the condition of medium and low temperature, with the increase of added amount citric acid has strong retarding action, but under the condition of high temperature, retarding effect is a curve, when added amount is more than 0.8%, as coagulant; At various temperatures, citric acid, the action of the cement slurry are scattered dispersion effect especially for brine water mud; Citric acid can improve the analysis of the slurry water. However, citric acid oxidation by all kinds of oxidant, thus affect the performance of different cement slurry system is not stable, if cement additive containing alcohol, or system temperature is exorbitant, citric acid reaction will occur.

Properties

Citric acid is a weak organic acid. It is a natural preservative and is also used

to add an acidic, or sour, taste to foods and soft drinks. In biochemistry, it is

important as an intermediate in the citric acid cycle and therefore occurs in the

metabolism of almost all living things. It also serves as an environmentally benign

cleaning agent and acts as an antioxidant. Citric acid exists in a variety of fruits

and vegetables, most notably citrus fruits. At room temperature, citric acid is a

white crystalline powder. It can exist either in an anhydrous (waterfree) form or as

a monohydrate the monohydrate forms when citric acid is crystallized from cold water.

More than 50% is being used as acidulent in beverages and some 20% in other food

applications. 20% is being used for detergent applications and 10% for other non food

related applications like cosmetics and chemical industry.

Usage

1. In the food industry, it is used as the acidulant in the making of soda, candy, biscuit,
can, jam, juice and so on. Moreover, it can be used as the antioxidant of grease.

2. In the medicine industry, it is the raw material of many pharmaceuticals, such as
ferric ammonium citrate (blood tonic), sodium citrate (blood transfusion agent) and
so on. Moreover, citric acid is also used as the acidulant in lots of medicines.

3. In the chemical industry, esters of citric acid can be taken as the non- toxic plasticizer to make the plastic film of food package.

4. It can be used as both the auxiliary agent in the industrial and civil detergent to
make nuisanceless detergent and the retarder in concrete. Moreover, it is also
applied to industries like electroplating, leather and ink.
