hydrophobic cement

The term "hydrophobic cement" refers to a type of cement that has been treated with a film-forming substance, such as oleic acid. This treatment is done to slow down the rate at which the cement deteriorates when stored in unfavorable conditions.1

Cement, in a broader sense, encompasses all adhesive substances. However, in construction and civil engineering, it specifically refers to finely ground powders that harden when mixed with water through a chemical process called hydration. This property allows some cements, like portland cement, to set and harden even underwater, earning them the name "hydraulic cements". Cements are typically mixed with inert materials like sand and gravel to form mortar or concrete, which are widely used in construction.234
