Masonry cement is made by adding a large amount of active or inactive mixed materials and slaking lime into Portland cement. This cement has better workability and water retention but lower strength. It can also be made from an active mixture of materials such as fly ash and lime or gypsum. The grade of masonry cement includes 225, 275, 325, etc.
