Mortar is a plastic mixture of cement, lime, sand and water.

The cement used in the production of mortar is also known as masonry cement.

It is a hydraulic cement that consists of one or the combination of the following:

  • Portland cement
  • Portland-pozzolan cement
  • Natural cement
  • Slag cement

The function of mortar is to bond individual masonry units and form a large single unit. It is also the bedding material to allow the masonry units to be placed on a levelled surface. This bedding can distribute pressure uniformly over the surface.

There are four grades of mortar, namely M, S, N and O. Each of these grades possess different proportion and property specifications.
