Demystifying the Technology: What is NanoPORE™ Advanced Lightweight Aerated Concrete (NLAC)?

Home / Services

NanoPORE™ Advanced Lightweight Aerated Concrete (NLAC) also known by various names like Foam Concrete, Foamed Concrete, or Cellular Lightweight Concrete (CLC). Despite the different terminologies, they all share a common core principle: the use of pre-formed foam to create a lightweight, cellular structure within a cementitious matrix. NLAC represents the pinnacle of this technology, utilizing advanced materials and precise control to achieve superior performance.

The Core Principle: A Marriage of Slurry and Foam

At its heart, NLAC is a homogeneous, stable composite created by meticulously blending two key components:

  1. Cement Slurry:This is the binding base of the material.
  2. Pre-generated Foam:This is the component that creates the lightweight, insulating cellular structure.

The quality and stability of the final NLAC product depend overwhelmingly on the quality of the foam and the efficiency of the mixing process.

The slurry provides the structural strength and matrix. Its composition can be adjusted based on the required density and application of the final NLAC product:

  • For Very Low Density (e.g., 400-600 kg/m³): The slurry is a simple mixture of Cement + Water. This creates a product with excellent thermal insulation, ideal for void filling, wall insulation and roof insulation.
  • For Structural Grades (e.g., 800-1600 kg/m³): A filler is added to the mix. This is typically Fly Ash (an eco-friendly industrial by-product) or finely graded Sand. The filler enhances the volume, reduces cost, and improves the long-term strength and durability of the cured concrete.

This is the technological heart of the process. The foam is not created by chemical reactions in the mix but is manufactured separately using a dedicated Foam Generator (Aerator). It is formed by combining three elements:

  • Advanced Aerating Chemicals (Foaming Agent): A specialized, protein-based or synthetic surfactant that traps air and creates stable, resilient bubbles.
  • Water: Diluted with the foaming agent to create the foam solution.
  • Compressed Air: Introduced into the foam generator, it expands the foam solution into a dense, dry-looking micro-bubble foam.

The quality of this foam—specifically the stability and size of the bubbles—is critical to the final properties of NLAC.
