Density and strength, considered together.
The profile describes concrete using lightweight aggregates such as volcanic pumice, clay, slate, shale, scoria, tuff and perlite. It reports Pioneer R&D work achieving a density of 1,800 kg/m³ while maintaining a compressive strength of 60 MPa.
Research considerations include water absorption, internal curing, thermal conductivity and fire performance. The suitability of any mix depends on the complete design and required performance, rather than density alone.
Potential applications
- Screeds and layers where additional weight is undesirable
- Roof insulation and specialist insulating applications
- Partition and panel applications
- Structural uses subject to design review and qualification
The stated density and strength are research results in the company profile. Confirm available mix designs with the technical team.
