Masonry Cement

St Marys Masonry Cement is a hydraulic cement produced specifically for use in mortar for unit masonry construction. Intergrinding of Portland cement clinker with plasticizers in the production of St. Mary’s Masonry Cement provides excellent plasticity, water retention and air entrainment. An adequate level of air entrainment enhances the freeze-thaw durability of mortar, which is important in the climate of the Great Lakes region.
