|
|
Term

| brick, stone (granite, travertine, limestone), concrete block, glass block, tile |
|
|
Term
| What affects the durability of the overall masonry construction? |
|
Definition
| the materials used, the quality of the mortar and workmanship, and the pattern that the units are laid |
|
|
Term
|
Definition
| designed by Finnish architect Alvar Aalto; dormitory at MIT; completed 1949; considered a seminal Modernist building that helped define the look of things to come in the U.S. |
|
|
Term
|
Definition
increase thermal mass of a building, very heat resistant, provides good fire protection
|
|
|
Term
|
Definition
| extreme weather may cause degradation of the surface due to frost damage; must be built upon a firm foundation to avoid potential settling and cracking; high weight increases structural requirements especially in earthquake prone areas |
|
|
Term
| Structural limitations of masonry |
|
Definition
| impressive compressive strength (vertical loads) but low in tensile strength (twisting or stetching) |
|
|
Term
| Tensile strength of masonry walls can be strengthened by __________ or ___________. |
|
Definition
| thickening the wall, or by building masonry "piers" (vertical columns or ribs) at intervals |
|
|
Term
|
Definition
| common brick, most widely used in construction |
|
|
Term
| Grade SW (Sever Weathering) |
|
Definition
| used in areas of heavy rain, snow, or continual freezing |
|
|
Term
| Grade MW (Moderate Weathering) |
|
Definition
| used in areas of average rain and moderate freezing |
|
|
Term
|
Definition
| used in areas of minimal rain and no freezing, as in sheltered or indoor locations |
|
|
Term
|
Definition
| cementitious material used to hold masonry units together; must be compatible with masonry units being used, strength required, and env. conditions |
|
|
Term
| four basic types of mortar |
|
Definition
| M, S, N, and O: each with different prop. of cement, lime, aggregate; each has diff. compressive strength |
|
|
Term
|
Definition
| similar to mortar, but is mixed to a pouring consistency and used to fill cavities or cores of masonry units |
|
|
Term
|
Definition
| binds individual masonry units together into a wall or building component, sealing the space between the units from air and water |
|
|
Term
|
Definition
| bonds the masonry units to the reinforcement |
|
|
Term
|
Definition
| white powdery deposit or crystallization on the masonry surface caused by soluble salts in the units of mortar (unsightly patches of discoloration) |
|
|
Term
|
Definition
| imparts decorative effect on the wall; makes the joint more watertight by compressing the mortar near the exposed surface |
|
|
Term
| how to achieve water tightness in a brick wall |
|
Definition
| select appropriate grade of brick and mortar for the climate; proper tooling of the joints to shed water; proper control-joint locations (to allow the wall to move and expand without cracks) |
|
|
Term
|
Definition
| common term for concrete unit masonry (CMU) |
|
|
Term
|
Definition
| hollow, loadbearing; solid, loadbearing; hollow, nonloadbearing; solid, nonloadbearing |
|
|
Term
|
Definition
| solid thickness that would be obtained if the same amount of concrete contained in the hollow unit were recast without holes |
|
|
Term
|
Definition
| made from burned clay and formed into hollow units with parallel cells; used for loadbearing masonry walls that will be finished with other materials, used as backup for exterior walls, and used as nonloadbearing interior partitions |
|
|
Term
| two types of structural clay tiles |
|
Definition
| side construction and end construction |
|
|
Term
|
Definition
| manufactured as either hollow or a solid unit; solid blocks can be used for flooring if correctly supported |
