Snow-melting Agent
Snow-melting agent often referred to as de-icer or anti-icer, is a chemical substance or mixture used to facilitate the melting and removal of snow and ice from various surfaces, such as roads, walkways, and airport runways. These agents play a crucial role in winter maintenance and safety by preventing the formation of ice or aiding in the breakup of existing ice layers. Common snow-melting agents include salts like sodium chloride (rock salt), calcium chloride, magnesium chloride, and potassium chloride. These salts lower the freezing point of water, leading to the formation of brine, which helps melt ice and snow by disrupting the ice-to-surface bond. Additionally, other chemicals, such as sodium formate, are employed as alternative de-icing agents. These agents are often chosen based on their effectiveness, environmental impact, and specific application requirements. While effective in enhancing winter safety, the use of snow-melting agents raises environmental concerns due to potential damage to vegetation, soil, and water bodies.

What Is Snow-Melting Agent
Snow-melting agents are sprinkled to prevent automobile slip. However, chlorine ions cause damage such as corrosion. The author has developed a new type of snow-melting agent that needs a great deal less an amount of calcium chloride and has a larger snow-melting effect than calcium chloride. The agent is a snow-melting agent with a two-layer structure in which a heat storage material is coated with a snow-melting agent. Our two-layer snow-melting agent has a snow melting effect 1.3 times and sliding friction effect 1.5 times greater than the snow melting agents on the market by using a 20% coating. The agent reduces the damage caused by the chloride ions to one-fifth and so it is a snow-melting agent with a small environmental load.
Advantages of Snow-Melting Agent
No shoveling
Say goodbye to backbreaking work and say hello to snow-free walkways, driveways, and patios. This is especially helpful for those who are unable to do the physical labor required for shoveling.
Safety
Snow melting driveway systems prevent slippery frost, snow and ice build-up reducing slip and fall accidents. For businesses, this can reduce liability and help meet building codes and provide safe walking surfaces for pedestrians. For homeowners, this will allow you to get up a steep driveway or make walkways safe, thus reducing liability.
Chemical-free
No more heavy bags of salt or chemical ice melt products. These chemicals can wreak havoc on the pavement, surrounding landscape, and can be tracked inside from foot traffic.
Longevity
Heating pavers, concrete, and stone surfaces evenly will add to their longevity. Surfaces that are heated unevenly are vulnerable to cracking and spalling. By eliminating scraping, chipping, and application of chemicals, surfaces will maintain their original appearance for years.
Active Ingredients of Snow-Melting Agent
A scoop of ice melt. The type of ice melt you choose should be based on several factors, including average outdoor temperature and if it'll come in contact with plants, animals or children. Here are the most common ice melt active ingredients:
Sodium Chloride (NaCl)
Also known as ice melt salt/rock salt. Melts ice and snow by lowering the freezing point of water. Helps keep surfaces dry. Corrosive and may damage concrete, wood and plants
Calcium Chloride (CaCl2)
Absorbs moisture from surroundings. Creates heat as it turns to liquid
Melts snow faster than sodium chloride (rock salt). Works well in extreme cold. Can burn skin and harm pets.
Magnesium Chloride (MgCl2)
Needs to be applied in larger amounts compared to calcium chloride
Less corrosive (compared to rock salt). Considered by many to be a pet-safe ice melt option. Easy cleanup.
Calcium Magnesium Acetate (CMA)
Less corrosive (compared to rock salt). Usually sold in liquid form
Biodegradable. Concrete-safe ice melt.
The frequent use of snow-melting agents such as chloride, acetate, and sulfate in road snow removal is bound to adversely affect the mechanical properties of the subgrade . The cemented soil, utilized as a standard roadbed filler, is vulnerable to various environments (freezing-thawing cycles and solution erosion), resulting in poor stability and durability problems. It researched the cemented soil's shear strength and found that the compressive strength decreased with the increase of freezing-thawing cycles. Discussed that with the increase in freezing-thawing cycles, the unconfined compressive strength and relative dynamic elastic modulus of cement soil at different ages decreased. Explored the effects of the curing period and freezing-thawing cycles on compressive strength, the mass loss rate, and deformation modulus. They proved that under the influence of freezing-thawing cycles and cement hydration reactions, the properties of the cemented soil under different curing ages were significantly different. Studied the erosion effect of various kinds and concentrations of chemical solution and different ph values on the cemented soil piles and proved that different types, concentrations, and ph values significantly affected the mechanical properties of cemented soil piles. It analyzed the destruction of the cemented soil by different concentrations of chlorine salt and obtained the internal action mechanism of chlorine salt on the destruction of the cemented soil by electron microscope analysis.
To improve the adverse effects of the external environment on the cemented soil, many scholars have investigated these parameters to achieve results beneficial for this field. Demonstrated that after nine freezing-thawing cycles, the unconfined compressive strength (ucs) and shear strength of clay treated with 1.0% nano-sio2 were 16% and 21% more than natural clay, which was not subjected to the freezing-thawing cycles. Also proposed that incorporating the basalt fiber or glass fiber into the cemented soil can effectively improve the ability of the cemented soil to resist freezing-thawing cycles and reduce its strength loss under freezing-thawing cycles through experimental research. Highlighted that incorporating fibers in the cemented soil can improve its peak stress and residual strength under freezing-thawing cycles. Furthermore, verified that the uniform incorporation of fibers in the cemented soil could improve its tensile and compressive strength. Obtained a series of conclusions by studying fiber-reinforced loess' mechanical properties under freezing-thawing cycles. These findings demonstrated that the strength and deformation of fiber-reinforced loess are better than those of plain loess after freezing-thawing cycles. Therefore, fibers improve the strength of soil and constrain deformation. From the study of images' observations reflected that thermal stresses due to freeze and thaw periods caused whiskers' growth from nano-sio2 surfaces. The whiskers and glass fiber modify clayey soil's strength properties and structure by creating filamentary networks on nano and macro scales, respectively. Furthermore, glass fiber produces less strength than popular additives such as lime and cement. However, it emits very low carbon dioxide into the environment compared to other additive materials, through the study of the mechanical properties and the pore structure of tailings in seasonal frozen areas, pointed out that the shear strength of tailings generally decreases with the increase of the freezing-thawing cycle time.
At present, scholars mainly focus on the mechanical properties of the fiber-reinforced cemented soil subject to freezing and thawing cycles, drying and wetting cycles, and the influence of salt solution erosion environment on cemented soil. However, there are few studies on the impact of cemented soil subgrade by snow-melting agents in cold areas. Based on this, to study the mechanism of cemented soil subgrade subjected to salt-freezing cycles in cold areas, three common snow-melting agents (potassium acetate, magnesium chloride, and sodium sulfate) were utilized to prepare solutions with the same concentration (0.2 mol/l).
Snowmelt Effect Analysis of Snow-Melting Agent
The outdoor temperature was −19°C during the time of the test. Three snow samples with a mass of 60 g were taken. Following snow collection, 10 g of 99% analytical pure powder of various test agents (magnesium chloride, potassium acetate, and sodium sulfate) was mixed with the same amount of snow samples to simulate the melting effect of multiple types of snow-melting agents on snow samples under normal road snow removal conditions. The experimental design time was 0, 10, 30, and 60 min, and the snow-melting effect.
It can be seen that the snow-melting effect of the snow-melting agent was more prominent with increased time. Simultaneously, the snow-melting effect of potassium acetate was the most significant, the snow-melting effect of magnesium chloride was second, and the snow-melting effect of sodium sulfate was the worst. On the one hand, the reason for the abovementioned situation is that after the snow-melting agent is dissolved in water (snow), the freezing point of salt water becomes lower than that of water at 0°C. Additionally, the lowest freezing point of magnesium chloride is about −20°C, the lowest freezing point of potassium acetate is about −30°C, and the lowest freezing point of sodium sulfate is −5°C. Therefore, the lower the freezing point, the better the snow-melting effect. On the other hand, experiments have demonstrated that the solubility of potassium acetate is higher than that of magnesium chloride below 0°C. At the same time, sodium sulfate is not easy to dissolve in water at low temperatures. Therefore, the higher the solubility at low temperatures, the higher the ion concentration in water. So as the liquid vapor pressure of water decreases, the solid vapor pressure of ice remains unchanged. To achieve the state of the solid-liquid vapor pressure of the ice-water mixture, the ice and snow melt are critical factors in the difference in snow-melting effects among the three.
It shows the apparent photos of the glass fiber-reinforced cemented soil after 0, 2, 4, and 6 freezing-thawing cycles in a water environment. It shows the apparent photos of the glass fiber-reinforced cemented soil after 5 freezing-thawing cycles in water, potassium acetate solution, magnesium chloride solution, and sodium sulfate solution.
It shows that the surface cracking phenomenon of the cemented soil in the water environment is more apparent with the increase in freezing-thawing cycles. After 2 cycles, pores gradually appeared on the surface. After 6 freezing-thawing cycles, the surface of the specimens was cracked. Due to the low temperatures, the water in the pores changes to ice, leading to increased expansion stress. When the expansion stress exceeds the tensile strength of the cemented soil, small internal cracks will occur. When it is melted again, more water enters the crack, and the crack increases when it is frozen again. Damage occurs gradually through repeated freezing-thawing cycles.
The specimens soaked in potassium acetate solution have small cracks and holes, but the overall structure is dense. The ones soaked in magnesium chloride solution have obvious cracks and peeling on the surface. Furthermore, the sodium sulfate solution had the most apparent destructive effect on the specimens, and the specimens had large cracks and falling blocks. Thus, it can be seen that sodium sulfate and magnesium chloride solution have a more serious erosive effect on the specimens, while potassium acetate has a less erosive effect.
Get a head start. When it begins to snow or ice, apply the product as soon as you can to prevent ice from forming. If there's snow accumulation, clear it away with a snow blower or shovel before applying the snow-melting agent. Apply the product in a thin layer. For dry products, use a handheld or wheeled spreader, or apply from the jug, bag or with a large cup. For liquid formulas, use a garden sprayer that hasn't contained pesticides in the past.
Some snow-melting agent ingredients can irritate your skin, so wear gloves and any additional safety gear specified by the manufacturer. Some snow-melting agents are corrosive and can damage concrete and plants. Once the ice has melted, remove any remaining residue with a shovel and dispose of it properly. Avoid shoveling de-icer in the grass or allowing it to accumulate near people, plants and animals.
Some products state that they're safe to use around pets. But even though deemed safe, some manufacturers' products contain a blend of components. When the bulk of that is rock salt, calcium chloride or magnesium chloride, use with caution around pets and plants to avoid injury and damage.
When spreading snow-melting agent around your home's exterior, it's important to wear the proper apparel to protect your skin from chemical irritation and the elements. If you have pets, you'll need to keep them safe as well. Here's a list of helpful items to consider. Heavy-duty work jackets and coats will keep you warm while working outside on a winter's day. If you live in a part of the us with incredibly cold weather or plan to be outside for long periods of time, consider a heated jacket.
Insulated boots will keep your feet warm when walking through the snow. And for days when the snow turns to slush, water-resistant boots will ensure your feet and upper calves stay dry. For icy weather, slip-resistant boots can help prevent falls. Protective headwear not only keeps your head and ears warm, but it also helps regulate your body temperature in a frigid environment. For your furry canine friends, pet shoes will protect your dog's feet from snow-melting agent chemicals and help prevent frost bite.
Factors to Consider When Choosing an Snow-Melting Agent
When it comes to snow-melting agent, there are a variety of options available. Different manufacturers offer different compounds, each with their own unique ingredients and price points. Some snow-melting agents may be more expensive than others, so it's important to do your research before making a purchase.
When choosing snow-melting agent products, consider the environment. Different chemicals in snow-melting agents can have varying effects on plants, animals, waterways, concrete, and metal. Always follow usage instructions to minimize risks and ensure safe, effective application.
The chemical composition of snow-melting agent plays an important role in how long it will provide de-icing action after application. Liquid snow-melting agents, though more expensive, offer longer residual action compared to solid forms. This can lead to fewer applications and reduced labor, making them a cost-effective choice for longer-lasting de-icing.
The lowest melting point is the temperature at which an snow-melting agent will be most effective. Snow-melting agents can be used at temperatures as low as -25°f, however, some are only effective down to 15°f.
In extremely cold temperatures, exothermic snow-melting agents are more effective. Endothermic snow-melting agents work better in moderately cold temperatures such as 15°f and above since it needs to draw heat energy from its surroundings in order to dissolve.
Snow-melting agents are available in both solid and liquid forms. Solid snow-melting agent works by creating a brine that breaks the ice's bond with surfaces, while liquid snow-melting agent is used as a pretreatment to prevent snow and ice from sticking.
