BCSA QUIZ 3 - MASONRY QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS) ALREADY
GRADED A+
Masonry is... Ans✓✓✓one of the oldest materials and simplest methods
of building.
Masonry was... Ans✓✓✓the first medium to present designers with the
endless arrangements possible with a stone or small unit.
Masonry refers to... Ans✓✓✓the material units of natural stone,
concrete, and brick, and is considered a modular construction material.
Today, masonry most often refers to... Ans✓✓✓clay bricks and concrete
masonry units (CMU's).
CMU Ans✓✓✓Concrete Masonry Unit. Made of Portland cement,
aggregates of various types, and water. CMUs rely upon a chemical
hydration process of the cement to durably bind the aggregates.
CMU Sizing Ans✓✓✓Are available in many shapes and sizes, with the
most common having nominal dimensions of 8 inches by 8 inches by 16
inches.
CMU Ans✓✓✓Like brick, can be laid up in many different bond
patterns. CMU walls are often also used as backup structural walls for
, stone, stucco, brick, and metal panels. The hollow cavity within the unit
can receive grout and reinforcing steel to give it strength.
C.M.U. Shapes, Textures, and Colors Ans✓✓✓Split-faced units: stone-
like appearance. Fluted or ribbed-faced units give a decorative
appearance. Ground-faced units are mechanically abraded to expose the
color of aggregate inside a relatively smooth exposed surface.
C.M.U. Grades Ans✓✓✓Describes its strength and performance around
moisture and water. In the U.S. Grade N is a load-bearing block with
compressive strength of 1,000 to 1,800 psi. These blocks can be used
either above grade or below grade and be exposed to water and moisture.
Grade S is also a load-bearing block but has limited use in exposure to
water and moisture and has lower compressive strengths. It is used
above grade and can be used in exterior walls that have a weather-
protective coating.
Derivative products Ans✓✓✓adobe, clay, tile, terra-cotta, glass block,
cast stone, and auto-claved aerated concrete are considered masonry
units because they are small and installed by hand, following the
principles of masonry construction.
Masonry is best used... Ans✓✓✓in a compressive state given its
intrinsic physical properties.
Four Types of Masonry Walls Ans✓✓✓Solid Masonry. Reinforced.
Cavity. Veneer. All can either be load-bearing or ornamental.
