Calcium Chloride 94%-97% Prills
An anhydrous pellet form of Calcium Chloride (CaCl2). It is the most widely
used and most effective of all cement accelerators.
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.
Synonyms:
CaCl2;
Calcium Chloride；
Anhydrous Calcium Chloride;
Calcium Chloride Anhydrous Granular;
Molecular Formula:CaCl2
Appearance:White solid particles, odorless, slightly bitter in taste, highly
hygroscopic and deliquescent.
HS Code:282720
CAS NO.:10043-52-4
EINECS:233-140-8
Physical and Chemical Properties:
Relative density:2.15(25℃）
Melting point:772℃
Boling point:1600℃
Solubility:Easily soluble in water, releases a large amount of heat when
dissolved. Highly susceptible to deliquescence when exposed to air. Easy to
dissolve in water,with a solubility of 74g/100ml of water at 20℃，while
releasing a large amount of heat (the enthalpy of dissolution of calcium
chloride is -176.2 cal/g).
Highly hygroscopic: easily deliquescent when exposed to air.
The state of the product after being damp: The water absorption is small, and
the external shape has not undergone significant changes, still in the form of
blocks; After absorbing water again, the surface begins to become wet, cold,
and loose, with a tendency to dissolve; Has a large water absorption capacity,
transforms from wet and cold small pieces into liquid, and then completely
dissolves in water.
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
