Low density
584 kg/m³ fresh, 559 kg/m³ dry and 626 kg/m³ after immersion. Design weight depends on service moisture conditions.

02Measured
Integrated thermal insulation
Thermal conductivity of 0.16910 W/(m·K) at a mean temperature of 24.02 °C. RSI of approximately 1.18 m²·K/W at 200 mm is calculated from the dry measurement, not directly tested at that thickness.
Source and scope R203Measured
Targeted mechanical strength
Compressive strength: 3.9 MPa at 28 days and 4.6 MPa at 56 days on the historical mix. These results inform assessment; design strength must be established for the project.
Source and scope R104Measured
Early strength development
2.0 MPa at 24 hours, then 2.6 MPa at 2 days. Curing and temperature matter. A 24-hour result does not authorise traffic or asphalt placement.
Source and scope R105Qualification required
Acoustic performance
To be qualified on the complete assembly, including thicknesses, finishes, floors and junctions. Primary acoustic reports must be matched to the application before a rated performance can be stated.
06Modelled
Installed-cost optimisation
Compare delivered and installed material, preparation, equipment, schedule and maintenance. The 2020 pavement study provides a life-cycle scenario, not a current project price.
Source and scope W07Application potential
Construction simplification
Continuous placement may offer construction advantages. Pumping, access, joints, protection and sequencing must be planned with the producer and applicator.
Source and scope R508Measured
Freeze–thaw behaviour
After 300 ASTM C666 Procedure B cycles: relative dynamic modulus of 86.5%. This characterises the tested specimens and cannot be converted into guaranteed years of service.
Source and scope R109Application potential
Durability
Freeze–thaw and scaling tests provide favourable evidence within their scope. Service life also depends on water, loading, interfaces and field monitoring.
Source and scope R110Modelled
Environmental performance
A life-cycle assessment compares pavement systems over 30 years. Layer selection, transport and maintenance affect the results. A new application requires its own assessment.
Source and scope W11Measured
Water behaviour
Absorption: 12.0% by mass after immersion and 3.6% by volume using two distinct methods. These results do not establish watertightness or universal hydrophobic behaviour.
Source and scope R112Qualification required
Capillarity
Capillary rise and its rate require a specific test protocol. Available absorption values do not replace that test.
13Qualification required
Environmental stability
Behaviour of the complete concrete in contact with water and soil must be documented for the intended use. A constituent data sheet is not a leaching test on the composite.
14Application potential
Buoyancy
Very low density requires assessment of water uplift. The designer considers saturation, cover loads, restraints and possible water levels.
Source and scope R115Qualification required
Self-levelling behaviour
Flow and stability must be checked on the delivered mix. A measured slump alone does not qualify the material as self-consolidating concrete.
Source and scope R116Qualification required
Fire performance
Reaction to fire and fire resistance must be qualified for the product and assembly. A cementitious matrix alone does not establish a fire rating.
17Qualification required
Mould behaviour
Moisture conditions, surfaces and finishes matter. Mould resistance must be supported by a suitable test.
18Qualification required
Dimensional stability
A length change of 0.020% is reported during freeze–thaw testing. It does not measure drying shrinkage, which requires separate characterisation.
Source and scope R119Qualification required
Vibration damping
To be evaluated for the frequencies, supports and constructed system. Static elastic modulus is not a measurement of dynamic damping.
20Application potential
Reduced seismic mass
Reduced non-structural mass can affect inertia forces. The actual effect, anchors and displacements require building-specific design; no seismic-resisting system is claimed here.
Source and scope R121Application potential
Precasting potential
Low weight and early strength open options for assessment. Demoulding, lifting, inserts and tolerances must be qualified for each element.
Source and scope R122Application potential
Fewer interfaces
Combining functions may simplify an assembly. The bonded asphalt test alone does not justify removing separation or drainage layers.
Source and scope R423Application potential
Platform versatility
Buildings, pavement insulation, fills and precasting are application families to assess separately. Evidence for one use does not automatically transfer to another.
Source and scope R524Qualification required
Fibres and reinforcement
Compatibility with fibres, reinforcement and anchors depends on the mix and use. Bond, corrosion and element behaviour must be verified.
