Surkhi, Powdered broken brick is used as an adulterant but it imparts strength and hydraulic properties to the mortar. To develop more strength is should be ground very finely with lime in the mortar grinding mill.
Surkhi mortar is a mixture of lime, surkhi and water. It is lime morta in which sand has been substituted by surkhi for economy and strength.
