Masonry Construction Exam Practice Tests
Course Introduction
Masonry Construction introduces students to the principles, materials, and techniques involved in building with brick, stone, concrete block, and other masonry units. The course covers topics such as material properties, structural behavior, bonding patterns, mortar types, codes and standards, and the use of reinforced and unreinforced masonry in contemporary construction. Emphasis is placed on safe work practices, estimating quantities, site preparation, and the execution of walls, arches, and other architectural features. Hands-on activities and case studies help students develop practical skills and an understanding of the role of masonry in sustainable and resilient structures.
