Construction masonry involves building structures using individual units such as bricks, blocks, stones, or concrete. These units are held together using mortar, a mixture of cement, sand, and water. Masonry is a durable, strong, and fire-resistant construction method commonly used for walls, chimneys, fireplaces, and other structural components. It is also a popular choice for aesthetic purposes due to the wide variety of colors, textures, and finishes available.
