Hydraulic cement refers to a type of material composed of calcined lime and clay that hardens after being mixed with water. It is particularly useful for repairing cracks, fatigue and other deformation on metal surfaces to prevent further infiltration and the onset of corrosion.
Hydraulic cement is non-corrosive and a non-shrink substance. It can be applied to metal surfaces as a temporary measure to prevent corrosion-lead degradation. Such a surface should be thoroughly cleaned and prepped prior to cement application to prevent trapping dirt or particles that may cause crevice corrosion.
Hydraulic cement has several advantages, such as:
Hydraulic cement is best applied in environments with minimal temperature variations.
