1

used for roofs,
poured mixture on reinforcing mat’l.
purlins support fiber plank or rigid insulation. wire mesh over this,
gypsum poured over min 2.5” thick.
highly fire-resistant.
Precast gypsum planks w tongue-and-groove edges in 2 & 4” thickness, up to 10’.

Poured Gypsum Decks

2

precast product, adding aluminium powder

Autoclaved Aerated Concrete (AAC)

3

blocks 10” high x 25” long x 4/8/10” thickness

Autoclaved Aerated Concrete (AAC)

4

uses epoxy-coated mesh.
precast panels thinner/lighter non-corrosive (less concrete req’d to cover)
thus, req smaller foundations/reduce transportation costs/speed erection process.

Carbon Fiber Concrete

5

⅕ density of conventional

Autoclaved Aerated Concrete (AAC)

7

gains strength by curing through ________ (vs. drying)

chemical reaction

8

can be placed purely by it’s own weight (vs vibration).
uses superplasticizer (polycarboxylate polymer)
flows easily around dense reinforcement
more uniform + smooth surface
faster

Self-Consolidating Concrete (SCC)

9

good sound control qualities/thermal mass/ greater airtightness than wood stud walls

Autoclaved Aerated Concrete (AAC)

11

gains __% strength during 1st week

70%

12

extruded to ultrathin fibers,
bundles into yarn like called tows,
laid in grid, intersections bound by heat-cured epoxy resin.
o.4” thick.
components of grid can be shifted to varying dimensions/strengths,
typ. 7x tensile strength standard steel mesh.

Carbon Fiber Concrete

13

unreinforced and reinforced panels produced for use as floor/roof/wall panel

Autoclaved Aerated Concrete (AAC)

14

critical moisture/temp maintained in

min 7day - 2 weeks.

15

resistant to insects, rodents and mold

Autoclaved Aerated Concrete (AAC)

16

if not cured completely, could lose up top:

30% strength

17

must be kept from freezing, or can lose up to
(b/c curing heats, cover w/ insulated plastic for few days)

50% strength

18

pouring/hardening/then curing in pressurized steam chamber

Autoclaved Aerated Concrete (AAC)

18

blocks are laid with thinset mortar, can be shaped with woodworking tools

Autoclaved Aerated Concrete (AAC)

18

must be protected from exterior environment w plaster/masonry/ext finish

Autoclaved Aerated Concrete (AAC)

19

less strength, non loadbearing only, and low-rise only
