Sèment

Sèment is a term in Haitian Creole used to denote cement, the binding material used in concrete and mortar. Cement is produced by calcining limestone with clay to form clinker, which is then ground to a fine powder and mixed with water and aggregates to form concrete or mortar.

The Creole form is generally traced to the French word ciment, and the spelling sèment reflects phonetic adaptation to Creole orthography.

Portland cement is the most widely used type; there are blended cements and specialized formulations designed for rapid strength gain, sulfate resistance, or low heat of hydration. The performance depends on particle size, fineness, and additives.

Cement is used in a wide range of construction applications, including foundations, walls, floors, and protective coatings. Proper curing, moisture control, and temperature management influence final strength and durability.

In some contexts, sèment may appear as a surname or place name, and the word may occur in discussions of architecture, construction materials, or regional markets.
