Concrete is the most
widely used type of construction material. The first six units cover the
physical characteristics, properties, and ingredients of concrete; the
form design and construction principles; construction procedures with
emphasis on concrete placement, finishing, and curing techniques; and
the proportions of ingredients.
Units 7, 8, and 9 cover masonry — basic tools
and equipment, properties, and mixing of mortar. Concrete masonry
includes the characteristics of concrete blocks, construction
procedures, and rubble stone masonry.
