|
Water sorptivity
|
400x170x100mm slabs subjected to 50mm hydro-static head in
rain machine.
Sample pre-dried for 21 days before testing.
|
d24=8-13mm@28 days
|
Exceeds requirement eg for AS3600 exposure classification
B2.

|
Thermal conductivity
|
Guarded hot box method complying with ASTM C 518,AS/NZS 4859
|
0.35-0.6 W/mK for lab dry densities ranging from 900-1,400
kg/m3
|
Thermal conductivity of normal density concrete typically
ranges between 1.5 to 2.5 W/mK
|
|
Fire resistance
|
Fire curve as per AS1530.4 on 1m2 wall panel area
Raw joints with no fire retardant sealing
|
For 75mm thick panel
2.5 hours to insulation failure
1.2 hours to joint failure
|
Panel tests with raw joints
- no fire retarding joint seal
|
|
Structural bending strength
|
600x1, 800x100mm panels reinforced with single F62 mesh
at centerline
4 point bending at 540mm centres
|
Serviceability bending capacity up to 1.5MPa
|
- Up to 3 times less than N40 concrete
- Ability to resist ultimate strength and serviceability limit
state wind loads for 3m spans
|
|
Pull-out strength
|
Tests on No 14 Tapcon threaded fastener and D6058 Dynabolt
|
3 kN for Tapcon
2 kN for Dynabolt
|
Capable of fixing 200kg/linear metre loads. (eg: cabinets
and contents)
|
|
Impact strength
|
Hard impact tests and measurement on diameter of indentation
0.5 and 1.0kg balls dropped from heights of 400mm and 800mm
|
Diameter of indentation between 8-15mm
|
Impact resistance of N40 normal density concrete panels is
about 30% better than HySSIL
