Q

Type III (Portland Cement)

A
  • high early strength

- used for pre-cast cold weather construction

21
Q

Type IIIA (Portland Cement)

A
  • air entrained
  • high early strength
  • used for pre-cast cold weather construction
22
Q

Type IV (Portland Cement)

A
  • low heat of hydration

- used for dams and other large structures

23
Q

Type IVA (Portland Cement)

A
  • air entrained
  • low heat of hydration
  • used for dams and other large structures
24
Q

Type V (Portland Cement)

A
  • High sulfite resistance

- There is no Type VA!

25
Q

What s is air entrained concrete?

A
  • Tiny bubbles are added to concrete allowing water inside the concrete to freeze without inducing large internal stresses
  • has freeze thaw resistance
26
Q

Silicone (Sealant/Caulk)

A
  • used in bathrooms, high moisture conditions (doesn’t work on wood/gyp.)
  • excellent durability
27
Q

Butyl Caulk (Sealant/Caulk)

A
  • lower water vapor permeability, BEST water sealant

- also called polyisobutylene

28
Q

Polysulfide (Sealant/Caulk)

A
  • prolonged immersion in water

- best chemical resistance

29
Q

Polyurethane (Sealant/Caulk)

A
  • gutters, moisture and corrosion resistance, flexible

- high abrasion resistance

30
Q

Screeding

A

done with 2x4 wood member

31
Q

Darbying/Floating

A

follows screeding and done by hand, float to smooth surface

32
Q

Troweling

A

Smoothest finish

33
Q

TPO (Flat Roofing Material)

A
  • thermoplastic
  • seams can be heat fused (like PVC) which is an advantage when compared to EPDM
  • more flexible than PVC (but not EDPM)
  • more economical than PVC
  • combines advantages of PVC and EDPM
34
Q

R-value of an insulated glass unit with single air space?

A

2

35
Q

R-value of monolithic tinted glass

A

1

36
Q

R-value of insulated low-e glass w/ single air space

A

37
Q

R-value of argon filled insulated low-e glass

A

4

38
Q

Hot Water Pipes

A

CPVC and PB

39
Q

Cold Water Pipes

A

PB, DE, PVC, CPVC

40
Q

Graffiti Resistance

A
  • urethane based coating
  • acrylic coatings
  • RTV silicone rubber coating
41
Q

Wall Thickness of Plumbing Walls

A

fixture on one side of wall: 12”

fixtures on both sides: 16”

42
Q

Heat Strengthened Glass (HS)

A
  • falls between annealed and tempered
  • tempered is 2x stronger, but it has less spontaneous breakage
  • HS stays in opening if broken, but does not split into small pieces (like safety glass)
  • good when there’s a thermal concern such as spandrel all glass curtain wall
  • less optical distortion
43
Q

Tempered Glass

A
  • opposite of annealed glass
  • 4x stronger than annealed glass
  • Tempering done once glass cut to size
  • Tiny cubicles called “dicing” when broken
  • Safety glazing
44
Q

Heat Soaked Tempered Glass

A
  • most $$ treated glass

- much safer than other options

45
Q

PVC (Flat Roofing Material)

A
  • fully adhered
  • thermoplastic so can be heat fused (unlike FDPM)
  • fire resistant
  • better in warmer climates due to light color
46
Q

EDPM (Flat Roofing Material)

A
  • fastened in with batten bars (taped metal or plastic)

- better in colder climates

47
Q

Stucco

A
  • lighter than concrete or masonry curtain wall system
  • preferred in seismic areas because it does not add extra mass to structure
  • porous and breathable, allows rainwater to evaporate
  • can be applied to concrete, steel or wood
  • stucco over concrete is prone to mold due to lack of water drainage
  • scratch and brown coats are base coats
  • there are two finishes available for stucco:
    1. portland cement based and 2. acrylic polymer based
48
Q

Hot Rolled Steel

A
  • rolled heat billets to required cross section

- primarily used for structural framing members

49
Q

Cold Rolled Steel

A
  • Required shape achieved by bending thin steel sheets at room temperature
  • Sheets are not heated before shaping
  • Lightweight (“lightweight gauge steel”)
  • Typical applications: roof decks, floor decks, wall studs
