In reading 3 and 4, it let me know the material about stone and masonry. Masonry consists of building structures from single units that are laid and bound together with mortar. Brick, stone, and concrete blocks are the most common materials used in masonry construction. Masonry is a popular construction technique around the world, due to its many advantages. Masonry is non-combustible, so it improves fire protection for the building and its occupants. Masonry offers high resistance against rotting, pests, weather, and natural disasters such as hurricanes and tornadoes. Being durable and resistant, Masonry can withstand large amounts of compressive weight loads.


The exterior walls of a house have several functions. Not only do they define the shape of a house, but they also support the floors, walls, and roof.
