CMP 210 EXAM 2 STUDY GUIDE
reinforced masonry - Answers :used then flexural, compressive, and shear stresses
exceed those permitted for partially or unreinforced masonry
cavity wall construction - Answers :generally used for exterior walls because they can
control moisture penetration and be insulated
expansion joints - Answers :create space between adjacent parts of masonry
construction and permit a limited amount of movement
control joints - Answers :provide tension relief between parts of masonry walls that may
change from their original dimensions (control where crack occur)
weep holes - Answers :opening left in the mortar joint - used to direct moisture out of the
building
tooled joints - Answers :best for resisting leakage
weathered, concave, or v-joints
arches - Answers :form of curved construction used to span an opening, usually
consists of wedge-shaped blocks called voussoirs
rubble - Answers :stone found naturally in irregular shapes and sizes
ashlar - Answers :type of masonry that uses units cut into squared shapes
dimension stone - Answers :large sqaure blocks
flashing - Answers :placed wherever there is a break in the cavity
thin materials impervious to water needed to prevent penetration and provide drainage
surface clay - Answers :shale and fire clay, reside near surface and is strip mined
shales - Answers :clay subject to high pressure causing it to be hard
fireclays - Answers :found at deeper levels and have more uniform physical and
chemical properties, can withstand higher temps, used in fireplaces
calcareous clays - Answers :15% calcium carbonate and have a yellow brown color
when burned
non-calcareous clays - Answers :contain silicate of aluminum, feldspar, and iron oxide,
takes a red/salmon color when burned
, stiff-mud process - Answers :method of forming brick, passes clay of 12-15% moisture
through a vacuum that removes air pockets
soft-mud process - Answers :used when clay has more than 15% moisture, burns bricks
until they've reached desired level
solid amasonry - Answers :(brick classification) if they have cores whose area does not
exceed 25% of the gross cross sectional area of the brick
modular bricks - Answers :actual size plus a mortar joint can be assembled on a
standard unit or model
hollow clay masonry - Answers :comprise units whose net cross-sectional area in the
plane of the bearing surface is not less than 60% of the gross cross-sectional area
weathering index - Answers :reflects the ability of clay masonry units to resist the effects
weathering
kiln - Answers :low pressure steam box, allows units to attain strength and harden. 1-3
hours
autoclave - Answers :uses high pressure on steam for 2-5 hours
concrete masonry - Answers :units made of relatively dry mix of portland cement,
aggregates, water, and in some cases admixtures
double tees - Answers :designed to span longest distances (4,8,10,12 ft) depths (10-
40") with lengths greater than 100 ft. although longer than 60 can cause transportation
issues
single tees - Answers :width (6,8,10,12 ft) depths (16-48") same lengths as double tee
precast concrete columns - Answers :usually combined with beams to form post beam
structural framework
conventionally reinforced
haunches - Answers :projections used to support beams on two or three sides
beams and girders - Answers :pre-cast, pre-stressed, can be used in any building in
which pre-cast construction is required
grouts - Answers :and mortars are used to transfer loads between members
rigging - Answers :refers to equipment, cables, slings, and other hoisting equipment
used to lift precast units into place
