Low density
584 kg/m³ fresh, 559 kg/m³ dry and 626 kg/m³ after immersion. Design weight depends on service moisture conditions.
Explore the characteristics and functions of the BLC platform. Each topic distinguishes measurements, modelling and items requiring application-specific qualification.

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.
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.
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.
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.
Compare delivered and installed material, preparation, equipment, schedule and maintenance. The 2020 pavement study provides a life-cycle scenario, not a current project price.
Continuous placement may offer construction advantages. Pumping, access, joints, protection and sequencing must be planned with the producer and applicator.
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.
Freeze–thaw and scaling tests provide favourable evidence within their scope. Service life also depends on water, loading, interfaces and field monitoring.
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.
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.
Capillary rise and its rate require a specific test protocol. Available absorption values do not replace that test.
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.
Very low density requires assessment of water uplift. The designer considers saturation, cover loads, restraints and possible water levels.
Flow and stability must be checked on the delivered mix. A measured slump alone does not qualify the material as self-consolidating concrete.
Reaction to fire and fire resistance must be qualified for the product and assembly. A cementitious matrix alone does not establish a fire rating.
Moisture conditions, surfaces and finishes matter. Mould resistance must be supported by a suitable test.
A length change of 0.020% is reported during freeze–thaw testing. It does not measure drying shrinkage, which requires separate characterisation.
To be evaluated for the frequencies, supports and constructed system. Static elastic modulus is not a measurement of dynamic damping.
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.
Low weight and early strength open options for assessment. Demoulding, lifting, inserts and tolerances must be qualified for each element.
Combining functions may simplify an assembly. The bonded asphalt test alone does not justify removing separation or drainage layers.
Buildings, pavement insulation, fills and precasting are application families to assess separately. Evidence for one use does not automatically transfer to another.
Compatibility with fibres, reinforcement and anchors depends on the mix and use. Bond, corrosion and element behaviour must be verified.
