Document Summary
Masonry is made up of materials that we stack to create a homogenous structure. If the materials are strong enough you can dry stack. Either structural or decorative, but still used as a cladding for a building for protection. Spanning the opening: metal lintel often used now. Back in the ancient days corbeled arch and a true roman arch. The industrial revolution brings steel structures to the us and masonry is no longer used for load bearing. The thickness of the masonry walls is in proportion to the height. The higher up you go the thinner the walls get because they don"t have to hold as many floors. This was the last of the load bearing masonry building thanks to the invention of steel. Hydrated lime males the mortar smooth and workable. Aggregate (sand) must be clean and sized properly. Grout is joint filler that has more water or polymer based and typically non-structural.
