An anhydrous pellet form of Calcium Chloride (CaCl2). It is the most widely used and most effective of all cement accelerators.
T&P Product Page
Normally 1 to 3% calcium chloride based on the cement is used. In general calcium chloride is added to cement slurries to shorten the setting time and/or accelerate the hardening process. It can also be used to offset the delay caused by other additives such as dispersants, fluid loss additives and retarders.

Chemical Stability:
·Stable under normal temperature and pressure
·Avoid moisture, heat, and high temperatures Easy to dissolve in water, ethanol, and acetone. Highly hygroscopic, easily deliquescent when exposed to air. Easy to dissolve in water and release a large amount of heat, its aqueous solution is slightly acidic. Dissolve in alcohol, acetone, and acetic acid. Reacting with ammonia or ethanol, CaCL2 · 8NH3 and CaCL2 · 4C2H5OH complexes are formed, respectively. The precipitate that crystallizes from an aqueous solution at room temperature is usually hexahydrate. When gradually heated to 30 ℃, it dissolves in its own crystal water and gradually loses water upon further heating. At 200 ℃, it becomes dihydrate, and when heated again to 260 ℃, it becomes white porous anhydrous calcium chloride.
Easy to absorb moisture. The solubility in 100g of water is 74.5g (20 ℃) and 159g (100 ℃).
·At room temperature, due to the crystallization of aqueous solutions, they often form hexahydrate salts. When heated to 30 ℃, it dissolves in its own crystal water and gradually loses water by further heating. At 200 ℃, it becomes a dihydrate salt, and when heated again to 260 ℃, it becomes white porous anhydrous calcium chloride. At this point, water reacts with anhydrous calcium chloride and also generates CaO.
·Contact with the skin can cause corrosion and blistering
Spray drying dehydration method
spray the refined neutral calcium chloride solution that has removed arsenic and heavy metals from the top of the spray drying tower through a nozzle to form a mist, and carry out countercurrent contact with the 300 ℃ hot air flow to dry and dehydrate to obtain the product.
The product has uniform particle size, aqueous solution is clear, superior quality, and it is environmentally friendly, safe and non-toxic.
·Used for manufacturing calcium salts：due to its chemical formula CaCl ₂ and absence of crystal water, it has fewer impurities and is suitable for producing high-purity calcium salts. High purity raw materials can ensure the quality and stability of the final product. It can also react with various metal oxides or salts to generate corresponding calcium salts. This high reactivity enables anhydrous calcium chloride to quickly participate in the reaction during the production process, improving production efficiency.
·Used for manufacturing microbial suppressants and pickling agents.
·Used for manufacturing refrigerator desiccants and deodorizers. Anhydrous calcium chloride has strong hygroscopicity, which can absorb moisture from the air, generate CaCl ₂ -2H ₂ O, reduce environmental humidity, achieve drying effect, thereby reducing the growth of mold and bacteria in humid environments, and also achieve deodorization effect.
·Used for manufacturing desiccants of container goods, such as apples, cherries, cocoa, etc
·Used to remove fluoride from water. mainly through chemical precipitation to remove fluoride ions from water. When anhydrous calcium chloride is added to fluorine-containing water, it reacts with fluoride in the water to form insoluble calcium fluoride (CaF ₂), which is separated from the water by filtration or precipitation to achieve the goal of removing fluoride.
CaCl2+2F−→CaF2↓+2Cl−
·Used to rescue magnesium salt poisoning. It belongs to high concentration calcium and competes with magnesium, so it is often used for detoxification of magnesium poisoning in clinical practice
·Used for the breeding of aquarium coelacanths and mollusks, such as sea anemones, jellyfish, corals, etc. Generally, anhydrous calcium chloride is used as an additive to increase growth rate, enhance immunity, and improve water quality.
When using anhydrous calcium chloride,appropriate protective equipment such as gloves,goggles,etc.,should be worn to prevent dust inhalation or direct contact with the skin,causing irritation or burns.

Calcium chloride (CaCl2) is one of nature’s uncommon wonders. It’s a specialty salt with unique properties that improves driving and pedestrian safety, suppresses dust from the air we breathe, and enhances the performance of products and processes that contribute to the supply of energy, food, and other essentials of life.
OxyChem’s calcium chloride is refined from natural brines found in sandstone formations beneath the earth in a non-synthetic process, avoiding the need for reactions with chemicals used in other CaCl2 manufacturing processes.
Calcium chloride has three unique and highly effective performance properties:
Calcium chloride is an exceptional ice melter because it quickly and easily dissolves into a brine solution, while releasing heat to speed up the ice melting process. It is also a highly effective dust suppressant and stabilizing agent in unpaved roads since it attracts water from the air binding gravel particles together.
Effective ice melting depends on selecting a deicer capable of melting ice quickly and efficiently under winter temperature conditions typical in your area, and then applying it properly. Several performance characteristics should guide the selection of an ice melter, but two are particularly important:
When the goal is keeping sidewalks safe under all conditions, calcium chloride stands apart from other options as it maintains ice melting power down to -25°F (-32°C). In contrast, other deicers like rock salt, potassium chloride and calcium magnesium acetate begin losing effectiveness between 25°F (-4°C) and 0°F (-18°C).
Calcium chloride’s hygroscopic properties means that it melts ice faster than other deicers. Calcium chloride attracts moisture from the surface and the surrounding air, forming an ice-melting brine faster that lowers the freezing point of water and gives melting action a faster start.
While most other deicers depend on their surroundings for heat, calcium chloride generates heat as it dissolves to form ice melting brine. This heat release is especially important during cold weather when other deicers lose effectiveness.
Round-shaped ice melters like PELADOW® Calcium Chloride Pellets can bore through ice quickly to penetrate and break ice’s bond with underlying pavement.
Flat or crystal-shaped ice melters like DOWFLAKE® Xtra or COMBOTHERM® spread out over the surface of ice as they dissolve.
Avoid being misled by performance claims touted by blends that are little more than attractively packaged rock salt containing insignificant amounts of higher-performance ice melter. Always ask for a formal statement from the manufacturer or distributor identifying the precise product ingredients by percentage. In blends containing calcium chloride and rock salt, look for at least 20% calcium chloride content to see an appreciable increase in performance over rock salt alone.
PELADOW® Calcium Chloride Pellets can melt more snow and ice with LESS TIME, LESS COST and LESS WASTE.

Calcium chloride and magnesium chloride are both salt compounds, solids at room temperature, highly soluble in water, and used for melting snow and ice. But there are important performance differences that should be considered when choosing between the two.
Effective dust prevention measures are essential to preserving the drivability and durability of unpaved roads, minimizing impact on the natural environment, and protecting the health, safety, property, and quality of life of those who live on, work near, or travel on gravel roads.
Calcium chloride is a hygroscopic salt that draws moisture from the air to form a solution in road gravel that keeps road surfaces constantly damp—even in hot, dry conditions. The moisture helps to bind particles together to create a hard and compact road surface. Because it penetrates several inches into the road base, calcium chloride contributes to overall road surface stability. It also depresses the freezing point of the moisture in the road surface to help minimize frost heave damage in the winter.
Three frequently used dust suppressants are calcium chloride, magnesium chloride, and mineral well brines. All contain hygroscopic materials that draw moisture from the air providing extended dust suppression by forming a solution in road gravel keeping road surfaces constantly damp. However, the performance differences should be noted and considered before choosing which to use.
