Sulfate-resistant cement: this cement type can withstand environments where there are high concentrations of sulfates such as soil or groundwater, such as foundations, pile foundations and drainage projects that contain these compounds. Its special characteristic lies in containing less than 5% C3A content with (2C3A+C4AF) content below 25% in order to effectively prevent corrosion caused by sulfate on concrete1.
Marine cement: Marine-grade concrete is ideal for structures located within aquatic environments such as seawalls, breakwaters and piers. It features low C3A content (less than 8%) while total (2C3A+C4AF) content of less than 30% can provide effective resistance against chlorides ions and sulfates found in seawater that cause corrosion of concrete structures.
Anti-corrosion cement: designed specifically to meet the rigorous demands of chemical environments like fertilizer plants, oil refineries and electroplating plants, this special type of mortar has a C3A content below 10% while (2C3A+C4AF) exceeds 35% - this ensures effective resistance against corrosion caused by various organic acids, inorganic acids and alkalis found on concrete surfaces.
Antifreeze cement: this special cement can be found at construction sites located in cold regions or during winter, such as bridges, tunnels and roads in cold climates, such as bridges. Tunnels or roads. Antifreeze cement's C3A content should exceed 15% while (2C3A+C4AF) should surpass 40% to increase cement hydration speed while increasing early strength development and prevent concrete freezing4.4.
