Due to the heat emitted during the dissolution process, calcium chloride can be used to melt ice. It can also act at lower temperatures than sodium chloride. For this use, it is in the form of small balls a few millimeters in diameter (as in the photo at the start of the page).

It is considered less toxic than sodium chloride for the soil and plants, but it can affect bacterial life of the soil, and it has been part of the herbicides approved until the mid -1950s ("especially effective in the vegetative stage and at the time of the start of vegetation, the use of salt as a post - lifting is described in the works of the time ( 1933)

It is used when mixing concrete to speed up the socket. He does not increase the final resistance. It has the disadvantage of corroding the reinforcement of reinforced concrete.

It is used on certain highways to fix the dust: by reacting with the humidity of the air, it makes it possible to maintain a thin liquid layer on the surface of the road which keeps the dust.

It is used in food, no E509, in particular to solidify the alginates, gelling. In addition, it is added to industrially cooked foods to increase the cell hardness of food (strengthening, stabilizing and thickening [12]), as in pickles (crunch [13]), olives, apple compotes, beans in jars.

It is also used in molecular biology, it makes it possible to make bacteria competent by degrading their lipopolysaccharides surface. He thus makes them fit for transformation by a vector.

It can also be used as a cell transfection agent with animal cells.CACL2 solutions have the property of making the cell walls of certain bacteria more porous (notably E. coli). This makes it a product used in the laboratory in genetic research.

Calcium chloride is used to dry the Varech (algae mixture) used for the production of sodium carbonate.It is also used in salt dehumidifiers to absorb air humidity in domestic and other environments.

Calcium chloride is used to increase water hardness in swimming pools. This reduces concrete erosion in the pool. By the principle of the chatelier and the common ion effect, increasing the concentration of calcium in water will reduce the dissolution of calcium -based compounds present in concrete. [Ref. necessary]

In marine aquariums, calcium chloride is added to provide organic calcium for shell animals such as molluscs and certain cnidaires. Lime water or a calcium reactor can also be used to introduce calcium into water.

However, the addition of calcium chloride is the fastest method and is the least effective on the pH.

In food and food:

As an enhancement agent, calcium chloride is used for canned vegetables, for curled soy milk in the tofu and for the production of a caviar substitute from vegetable or fruit juice [14];It is commonly used as an electrolyte in sport drinks and others, including bottled water;

The property that calcium chloride to lower the melting points is used to slow the solidification of caramel in chocolate bars;

For brewing beer, calcium chloride is sometimes used to fill the mineral inadequacies of brewing water. It affects the taste and chemical reactions during brewing, and can also affect the action of yeast during fermentation;

Calcium chloride is sometimes added to the milk treated or transformed in order to restore the natural balance between calcium and protein in casein when making cheese;

It is frequently added to apples slices to keep their texture.

Medical uses:

It is injected to treat internal burns to fluorhyder acid;
It can be used to treat magnesium poisoning;
It can help protect the myocardium from dangerously high levels of potassium in the blood in hyperkalemia.

Diseases such as powdery mildew and a gray mold called botrytis can wreak havoc on foliage and flowers, especially in the greenhouse environment. From help and research from The Ohio State University Agricultural Technical Institute in Wooster, Ohio, we have begun applying a commonly used ice melter to prevent plant diseases in our greenhouse. Dowflake's calcium chloride, while it's inexpensive and natural, has shown to be very effective in controlling these common greenhouse diseases.

an well finally found some sites mentionning cacl2 is also used as a highly water-soluble calcium source for the formulation of liquid fertilizers and for fertigation



so nevermind about cacl2 seem i finally digged it out.
