Cement with low heat of hydration and high sulfate resistance is preferred for sea shore area.

• Cement with low C3A content is preferred as it reduces the risk of sulfate attack.

• Cement with low heat of hydration is preferred as it reduces the risk of thermal cracking.

• Blended cement with fly ash or slag can also be used as they have better resistance to sulfate attack.

• Examples of such cement are Portland Pozzolana Cement (PPC) and Portland Slag Cement (PSC).
