Researchers pave the way to salt-resistant concrete

Pavements could soon be saved from some of the ravages of the winter chill thanks to a new type of low-cost concrete that absorbs significantly less of the salt that gets spread on it annually.

Sodium chloride

Sodium chloride, also known as common salt, table salt, or halite, is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt, it is commonly used as a condiment and food preservative.
