Sodium chloride also known as rock salt, is the most common deicing salt. Rock salt releases the highest amount of chloride when it dissolves. Chloride can damage concrete and metal. White Rock Salt is used where cleanliness and hygiene are a priority, as it leaves little or no residue. Conforms to BS3247:2011, the British Standard for de-icing salt. Marine salt harvested from sustainable
The amount of rock salt to be used varies depending on the temperature and location. For example, steep hills and sharp bends will benefit from more rock salt compared to flat and straight roads. However, we recommend that 10-15 grams of rock salt are to be spread per square metre. This amount can increase to
All salt contains two basic elements: sodium and chlorine. Sodium (chemical symbol Na) is a silvery-white metal that reacts violently when mixed with water and oxidises in air. Chlorine (chemical symbol Cl) is greenish-yellow and exists as a gas at room temperature. Because both elements are so volatile, they're found in nature as part of compounds like sodium chloride (NaCl), which
Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius), and that includes ice on roadways. Road salt works by lowering the freezing point of water via a process called freezing point depression. The freezing point of the water is lowered once the salt is added, so it the salt makes it more difficult
Yes. Salt will work at temperatures down to minus 8-10 degrees Celsius. Below that temperature, salted roads will still freeze. Sodium chloride also known as rock salt, is the most common deicing salt. Rock salt releases the highest amount of chloride when it dissolves. Salt melts ice and snow by lowering its freezing point. Salt is best put on the roads before they freeze or before snow arrives. Then,
