CON 151 CSU Exam 2
Masonry joints - ANS -Troweled and tooled
Weathered joint - ANS -Best troweled mortar joint
Flush joint - ANS -Produces hairline crack, trowel pulls Mortar away from masonry
Raked joint - ANS -
Cold weather for masonry - ANS -Hydration slows at 40 degrees, protect for 24 hours
Pointing - ANS -Process of filling in holes in the mortar or defective mortar joints
16 divisions - ANS -1. General conditions, 2. Site construction, 3. Concrete, 4. Masonry, 5.
Metals, 6. Woods and plastics, 7. thermal and moisture protection, 8. Doors and windows, 9.
Finishes, 10. Specialties, 11. Equipment, 12. Furnishings, 13. Special construction, 14.
Conveying systems, 15. Mechanical, 16. Electrical
Light wood Framings pros + cons - ANS -pros- Flexible- Easily constructed- Economical
Cons- Burns rapidly, - Decays if exposed to moisture- Changes volume with moisture changes -
Framing unattractive (must be covered)
Coniferous wood - ANS -soft woods, usually bear cones
Deciduous wood - ANS -hard woods, shed their leaves
Cmu block size - ANS -8'x8'x16'
Ton - ANS -2000 pounds
Crane load equation - ANS -Wieght x leanth x quantity
/ 2000, then see how much crane can hold
dry wood vs wet - ANS -dry=stronger wet=weaker
fiber saturation point - ANS -fibers fully saturated and cells are empty, 30%, dimensional
instability, shrinkage begins
, equilibrium moisture content - ANS -moisture content that is equal to the moisture content of
the atmosphere, wood should be fabricated and installed close as possible to where it will be
used
decay resistance - ANS -insured under 20%, can be treated with toxic chemicals, won't rot,
heartwood=naturally decay resistant
tensile stresses - ANS -stretching forces
compressive forces - ANS -squeezing forces
bending stresses - ANS -force acting perpendicular to its leant like a beam
parts of tree - ANS -outer bark, inner bark, Cambrian layer, sapwood, heartwood, pith growth
rings,
rings - ANS -hard/smaller cells=summer soft/larger cells=spring
wood warp types - ANS -bow=), twist=~, crook=(, cup=u
checking - ANS -separation across the growth rings
split - ANS -lengthwise grain separations from one surface to another
wood strength - ANS -strong in tensile strength parallel to the grain, weak in tensile strength
perpendicular to the grain
soft woods classified by - ANS -use, manufacture, size, grade
types of woods - ANS -yard lumber= ordinary building/general construction
structural lumber=2" or more in nominal thickness, use where working stresses are required
factory and shop lumber=for further manufacture in other products
size classification - ANS -nominal size, boards, dimensional, timber, rough size, dressed size
plywood - ANS -common size 4x8 grain runs parallel to the long axis
volume calculation - ANS -Change the numbers to a common form
of measurement, Feet.
Divide the number of inches by 12 to
convert inches to decimal feet.
Get the volume in cubic feet, L x W x H Convert the cubic feet to cubic yards,
divide by 27.
