Masonry Units

Concrete masonry is among the most surplus building materials present since a wide range of aspects can be accomplished using Concrete Masonry Units (CMU) as they have more benefits than stone or brick masonry. CMU are manufactured in a variety of shapes, colors, sizes, and patterns for various functions and finishing. Due to their modular properties, different CMU can be mixed in the same wall for various textures, colors, and so on. For the formation of the concrete blocks, cement, aggregate, and water are required.
