ABSTRACT This paper provides a comprehensive review of recent advancements in the use of stearic acid to develop superhydrophobic surfaces on cement‐based materials. Stearic acid is a widely used hydrophobic agent owing to its low cost, simple preparation, and broad applicability. The mechanism of stearic acid hydrophobic modification and its impact on material strength are systematically analyzed. The paper critically examines advanced strategies for constructing superhydrophobic concrete using stearic acid, particularly through external coating and internal mixing. The advantages and limitations of each approach are summarized. Stearic acid disrupts the hydration of cement‐based materials, potentially reducing their strength. The surface hydrophobic modification method faces the challenge of layer detachment. Finally, the challenges and future potential of applying stearic acid in superhydrophobic cement‐based materials are explored.
