· Limestone and sandstone have distinct differences in terms of strength and durability. Limestone, as calcite rock, is known for its durability and ability to withstand weathering. It's relatively resistant to damage so it's suitable for various applications, including limestone pavers. On the other hand, while sandstone is generally strong and

· Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements

B) Mix high-strength mortar appropriately. The type of mortar you’ll absolutely need to use for your limestone wall has a mix ratio of 2 parts cement, 1 part lime, and 9 parts masonry sand. Mortar mixed in this ratio develops a compressive strength of 1,800 pounds per square inch, and is known as Type S mortar.
