Title:

Specific Strength Attributed Self-Compacting Load Bearing Lightweight Roof/Floor Screed Using Sintered Lightweight Aggregates
Value Proposition:

This LECA-based self-compacting load-bearing lightweight roof/floor screed technology delivers a structurally strong, thermally efficient solution that slashes dead loads by up to 50% compared to conventional concrete. It achieves over 25 MPa compressive strength, superior flowability per EFNARC standards, and low thermal conductivity (1.39 W/mK), ideal for sustainable roofing in commercial, residential, and high-rise applications.
Summary Application:
  • Load-bearing roof/floor screeds.
  • High-rise structures and renovations needing weight reduction.
  • Green roofs, hospitals, and schools for insulation and sustainability.
Advantages:

Easy Application, Lower Thermal Conductivity, Dead Load Reduction, Structural Benefits.
Commercialization Status: Already Commercialised
