Non-hydraulic cement
Hydraulic cement:
Natural cement
Cement pozzollan
Slag Cement
Hydraulic Lime
White cement
Cement alumnia
Portland Cement

Portland cement pozollan: Natural cement a majority (65% -75%) of hydraulic lime made from limestone
Pozzolan cement: material containing sillisium or aluminum that has no adhesive properties
Slag Cement: 'that the majority of the hydraulic cement comprises a mixture of uniforms, and, strong of slag tanus high limestone and chalk tahor
Pozzollan portland cement: a mixture of Portland cement and materials are pozzollan
White cement: Portland cement is a low iron oxide content of less than 0.5%
Almunia cement produced from the burning of limestone and bauxite
