Dust Control - Concrete Accelerator:
Calcium Chloride has unique properties that make it ideal for maintaining unpaved roads and fortifying road bases for new construction. It is calcium chloride’s ability to regulate moisture on road surfaces that is the key to building roads that last.
Calcium Chloride keeps roads moist, day-in and day out, keeping nuisance dust down. Reduced pot-holing and rutting made possible by calcium chloride surface stabilization makes roads safer year round.
Stabilized calcium chloride roads can reduce aggregate loss by up to 75%. In addition, they significantly reduce the frequency and costs associated with periodic grading.
Uniform compaction and residual calcium chloride helps protect road bases from winter freezing and related frost heaving. Long known as an effective ice melter, calcium chloride lowers the freezing point of moisture in road bases to nearly 60 degrees below zero.
Calcium Chloride protection of unpaved roads and road bases is cumulative and long-tasting. The migration of calcium Chloride from road bases is minimal. Studies have shown that calcium chloride is still present and providing stabilization in road sub-bases nearly 30 years after initial construction.
Calcium Chloride maintains workability in concrete with reduced water usage. In addition, faster setting means that manpower and labor hours can be reduced. And the number of forms required for a project can be minimized, since they can be re-used faster at the job-site.
Calcium chloride is commonly used in industry as an accelerator. Accelerated rates of strength development allow for earlier removal of forms, earlier finishing operations and availability for use. This also allows for shorter curing and protection periods which can be advantageous, especially in cold weather conditions. Briefly, calcium chloride reduces initial and final setting, resistance to sulfate attack and bleeding. Tensile and flexural strength are slightly decreased. However, compressive strength, water tightness and modulus of elasticity are increased. Resistance to damage by freezing and thawing is improved early but may be less resistant at later ages.
One of the major problems encountered with the use of calcium chloride as an admixture is the effect that the chlorides have on reinforced concrete. Concrete can contain no significant amount of calcium chloride. The effect of corrosion hat the presence of chlorides may produce can be controlled if appropriate measures are taken.
Ice Melters
Calcium Chloride Liquid: a liquid brine in its natural state and is converted into a dry material by removing the water. It quickly absorbs water from the atmosphere. When calcium chloride is converted into a liquid, it gives off heat. Calcium chloride will melt ice at temperatures of-25° F.
The growing need for corrosion-inhibited deicers has prompted manufacturers to explore their production. One example of this is a new corrosion-inhibited grade of liquid calcium chloride designed to meet or exceed deicers standards in all respects. In addition to providing low corrosion versus salt, it has calcium chloride’s operational benefits in that it continues to melt snow and ice at 20 degrees F, the temperature at which salt becomes an inefficient deicer.
Those using corrosion-inhibited calcium chloride for deicing and anti-icing, report that it aggressively melts snow and ice, and that it offers operational benefits versus magnesium chloride, which was the primary deicer used in these areas, due to local availability.
Evaluations show that 25%, 30% and 32% aqueous solutions of the inhibited liquid calcium chloride produce just 4 to 7 mils/year of corrosion or 80% to 90% less corrosion than sodium chloride. The tests compared sodium chloride, regular and corrosion-inhibited calcium chloride, and water. Water is taken as the baseline, so its effects were subtracted from the corrosion values of the other materials.
Other advantages of the new corrosion-inhibited calcium chloride are its ability to cut through snow and ice more quickly than salt or magnesium chlr4ide, lack of sediment problems in tanks and easy clean-up of vehicles.
CALCIUM CHLORIDE (Pellet)
Description: Small, white pellets processed from naturally occurring material.
Relative deicing speed: Past acting deicer at all temperatures.
Lowest practical temperature: Down to -25° F.
Effect on concrete: Does not chemically attach concrete. Poses least threat of damage from freeze induced expansion pressure.
Effect on vegetation: Used as recommended, will not harm vegetation. Calcium Chloride is used as a calcium source for certain fruits and vegetables.
Residue: Leaves no powdery residue.
Manufacturer’s recommended application rate: 2 -4 oz/yd.
Comments: Calcium Chloride gives off heat as it dissolves therefore melting more ice faster at lower temperatures than other common chemical deicers.
