Lay a foundation for masonry work with concrete blocks key terms

Many construction projects call for the use of concrete blocks due to their durability and the fact that they can be shaped into precise forms. In a masonry company or a small home improvement business, the use of concrete block terms is essential. Knowing the correct concrete block terminology helps in the selection of the proper block for projects, in ordering concrete blocks from manufacturers and in giving educated explanations to customers.
