Mar 01, 2012 Cement lime mortar should not normally be used below the damp proof course dpc. Masonry cement mortar is used where the sand is suitable to give sufficient workability without lime or plasticiser. Mix ratios vary from 12.5 cementsand for a rich mix for structural brickwork, such as manholes in roads, down to 17 for more movement.
