calcium chloride can melt ice even at -67° below zero? Use Calcium when temperature is below zero. |
| …THAT |
rock salt (Sodium Chloride) works best at temperatures above zero Fahrenheit? |
| …THAT |
calcium chloride melts ice 7 times faster than rock salt? It’s Exothermic…creates heat as it dissolves. |
| …THAT |
lithium chloride is one of the most powerful ice-melting compounds known (melts ice at -112 degrees below zero), but
costs 50 times more than most other deicing compounds. |
| …THAT |
rock salt is approximately one-half the cost of calcium chloride? So, if the temperature is between 0°F and 32°F, use the
less expensive rock salt instead of calcium chloride. |
| …THAT |
“ice melting pellets” advertised as “non-tracking”, “Harmless to concrete”, etc., and sold under many trade names (at
higher prices), is actually calcium chloride anhydrous (regular calcium chloride heated to remove moisture), and reacts
slower with ice than regular calcium chloride flakes? Highway departments use the flake. (
(Formula of “ice melting pellets” –CaCl2 )
(Formula of regular calcium chloride flakes –CaCl2 · 2H2 O) |
| …THAT |
rock salt (sodium chloride) is the salt that dries out, recrystalizes and forms the white residues that can be tracked onto
floors and carpets? Calcium chloride does not dry out. It is hygroscopic (attracts moisture), stays “wet”, therefore, though
it can be tracked in, you can’t see it. |
| …THAT |
calcium chloride is used to keep dust down on unpaved roads, because it absorbs moisture from the air and keeps
the dirt “wet” and dust-free? Also causes dirt to “pack down” and harden. |
| …THAT |
salt mixed with sand, coal, ore, etc., makes the piles “freeze-proof”? |
| …THAT |
a mixture of one part calcium chloride and ten parts sand, when applied to ice on sidewalks, driveways, etc.,
Anchors the sand instantly and cannot be easily blown or worn away? |
| …THAT |
a 100 pound bag of salt in the trunk of an automobile puts weight on the rear wheels for extra winter traction and can be
available to use in emergencies when you get stuck? |
| …THAT |
calcium chloride solutions (40 pounds calcium chloride dissolved in 60 pounds (approximately 8 gallons)) of water are
used to full inflatable tractor tires to give extra weight and traction, and won’t freeze? (One gallon of this mixture weighs
11.6 pounds. |
| …THAT |
calcium chloride solutions are also used in highway “crash barrier” containers to cushion any accidental impact, and
will not freeze? |
| …THAT |
calcium chloride is used in concrete mixes to give quicker initial set and greater strength? (Below 70°F, use 2 pounds
per bag of cement: above 70°F, use 1 pound per bag of cement) or add to mixing water -4 pounds calcium chloride
per each gallon of water. |
| …THAT |
rock salt and calcium chloride do not, themselves, attack concrete and asphalt? It is the alternate freezing and thawing of
surface water, increased by the use of salt, that does the damage. (To lessen the chance of damage, use salt sparingly and
when ice melts, remove slush and water as soon as possible, so that surface dries before the next freeze.) or use non-
corrosive “UREA” ice melting crystals, which is least harmful to concrete. Ice melting chemicals should not be used on
concrete less than a year old. |
| …THAT |
calcium chloride absorbs 1 pound of water for each pound of its own weight? Good for drying out damp cellars. |
| …THAT |
UREA (NH2·CO·NH2) is good ice melting compound at temperatures above 11ºF? |
| …THAT |
UREA is less corrosive to metal and concrete? UREA run-off is also harmless to grass and foliage… it contains
nitrogen and actually enhances growth. |
| …THAT |
CMA (Calcium Magnesium Acetate) may be more acceptable as a less corrosive ice-melter from an environmental
standpoint, but costs 12 times more than rock salt? |
| …THAT |
Surpass Chemical Company, Inc., stocks, not only rock salt and calcium chloride for ice and snow, but also stocks
granular common salt, flour salt, solar salt and salt beads for water softeners? |
| …THAT |
you should buy salt early, before winter comes. If you wait until the roads and sidewalks freeze, you will find that salt will
be hard to find and higher priced because of the sudden demand. |
