Full Name

ICC-ES AC272 – Acceptance Criteria for Cellular Concrete

Scope

ICC-ES AC272 outlines the acceptance criteria for evaluating cellular concrete, a lightweight concrete with improved thermal insulation and fire resistance properties due to its cellular structure. The scope of AC272 includes:
  • Material properties: it specifies the requirements for the constituents of cellular concrete, including cement, aggregates, foaming agents, and other additives, as well as the resulting properties of the hardened concrete, such as density, compressive strength, and thermal conductivity.
  • Production methods: it addresses the different methods for producing cellular concrete, such as preformed foam, foam injection, and gas formation, ensuring the quality and consistency of the final product.
  • Testing procedures: it details the standardized testing methods for evaluating the physical and mechanical properties of cellular concrete, including tests for density, compressive strength, flexural strength, drying shrinkage, and thermal conductivity.
  • Evaluation and certification: it outlines the process for evaluating and certifying cellular concrete products to ensure they comply with the acceptance criteria and can be safely used in construction.
ICC-ES AC272 is crucial for manufacturers to demonstrate that their cellular concrete products meet the required performance and safety standards. It also provides valuable information to builders, designers, and engineers for selecting and using appropriate cellular concrete in various applications, such as roof insulation, floor fills, and wall panels.
