At what temperatures are icemelters really necessary?
Snow and ice storms generally occur between -18° and 0° Celsius ( 0° and +32°F ). This is when icemelters will effectively melt ice and snow.
What is an icemelter actually supposed to do?
Icemelters help to remove ice by breaking it down – first into smaller chunks, and finally into a liquid.
What different types of icemelter are there?
There are six different types of icemelter compounds on the market. They are:
Some icemelters are simply variations of these basic types, blended with a non-icemelting additive for marketing reasons. Many products sold today are merely re-packaged commodities of rock salt, natural or artificially coloured.
What forms do icemelters come in, and which is the most effective?
Icemelters (or de-icers) are available in pellets, granules, flakes, and liquid, with granules being the most effective. Flaked forms are best avoided for two reasons: They do not penetrate as deep as granules, and therefore do not liquefy beneath the surface of the ice, nor do they apply well in windy conditions. Pellets pose a similar problem: The round pellets often roll away in stormy weather.
What concerns do most people have about using icemelters?
What type of icemelter should be used on new concrete?
None. No icemelter should be used on newly poured concrete, as concrete requires a certain length of time to cure. This amount of time can vary depending on the type of concrete. It is best not to use icemelter on new or unsealed concrete less than 12 months old, exposed aggregate, brick, or pre-cast steps. Applying icemelter to damaged, cracked or chipped concrete may result in further damage due to the thaw and re-freeze cycles.
Which icemelters will harm or discolour concrete?
Some icemelters containing ammonium nitrate or ammonium sulphate additives will rapidly disintegrate concrete and therefore should not be used. Discolouring, however, is primarily caused by calcium chloride. How? Calcium Chloride accelerates the hydration process, but has a retarding effect of the hydration of the ferrite compound in Portland cement. This ferrite phase normally becomes lighter with hydration, however, in the presence of calcium chloride, the unhydrated ferrite phase remains dark.
What is concrete scaling and what is its cause?
Concrete scaling (or flaking) is the loss of surface mortar. This is a primarily physical action caused by the hydraulic pressure that occurs when water freezes within the concrete, as opposed to a chemically corrosive action. For this reason, it is necessary to extend the freeze/thaw cycle as long as possible. Calcium chloride icemelters have the shortest freeze/thaw cycle.
What is concrete spalling and its cause?
Spalling is a surface defect that is deeper than scaling. Spalls tend to occur over corroded reinforcing steel due to the present of chloride ions.
What type of concrete has the best resistance to scaling and spalling?
The type of concrete best at resisting these two effects is concrete where properly spaced air voids are present. Air-entrained concrete has an excellent resistance to surface scaling and mortar flaking due to freezing and thawing.
Why should people avoid using Calcium Chloride icemelters?
Beside the fact that calcium chloride causes damage to concrete by having a very short thaw/freeze cycle, and causes discolouration of concrete, Calcium Chloride inherently attracts moisture – is hygroscopic – and therefore has a limited shelf life. Further, Calcium chloride leaves behind an oily residue, which is easily tracked into buildings, soiling and damaging carpets and floorings and presenting a serious slip/fall hazard. Perhaps most frighteningly, it is harmful to the environment – damaging plant life, soil and the water system. Also, people must be very careful when using calcium chloride as it causes painful skin irritation.
Why should people avoid using Rock Salt or Sodium Chloride?
Rock salt has an enormously negative effect on the environment as it is toxic to vegetation and damaging to soil. The general impact of salt on grass, crops or vegetation is to impair or reduce growth. It does this by promoting high pH values which cause micronutrient deficiencies. Rock salt or sodium chloride is not only harmful to plant life but also the very soil that sustains life. Salt content in soils disperses both the clay particles and organic matter. This breakdown in the soil's aggregate structure reduces its permeability to air and water. As a result, root proliferation and penetration throughout the soil is impaired. Also, when these soils dry, they become hard and cloddy with a tendency to form heavy surface crusts.
