Calcium chloride

Calcium chloride, with the chemical formula CaCl2, has the CAS number 10043-52-4. It is a white crystalline solid that appears as a colorless to white powder. It has a strong, salty taste and is odorless. The basic structure of calcium chloride consists of one calcium atom bonded to two chlorine atoms. This compound is highly soluble in water, with a solubility of 74.5 g/100 mL at 20°C. It is also hygroscopic, meaning it can absorb moisture from the air. Calcium chloride is considered safe for general use, but it can cause irritation to the skin and eyes. It is not classified as a carcinogen or mutagen. However, it should be handled with care and proper protective equipment should be worn when working with it. Ingestion of large amounts of calcium chloride can cause gastrointestinal irritation and may lead to vomiting and diarrhea. In case of accidental ingestion, medical attention should be sought immediately. Calcium chloride is not flammable or explosive, but it can release irritating or toxic fumes when heated to high temperatures. It is important to store calcium chloride in a tightly closed container in a cool, dry place, away from heat sources and incompatible materials. It should be kept out of reach of children and pets.

Applicable Fields

De-icing and Snow Removal: Calcium chloride is commonly used as a de-icing agent to melt ice and snow on roads, sidewalks, and other surfaces. Its mechanism of action involves lowering the freezing point of water, which helps prevent the formation of ice. Calcium chloride also provides traction on slippery surfaces.

Dust Control: Calcium chloride is used to control dust on unpaved roads, construction sites, and other areas where dust can be a problem. It works by attracting moisture from the air, which helps to bind the dust particles together and prevent them from becoming airborne.

Concrete Accelerator: Calcium chloride is often added to concrete mixtures to accelerate the setting and hardening process. It helps to reduce the curing time and increase the strength of the concrete. The mechanism of action in concrete involves the reaction between calcium chloride and the cementitious materials, which promotes the formation of calcium silicate hydrate, the main component of hardened concrete.

Storage

Conditions: Store in a cool, dry place.
