Determination of creep strains under compression of autoclaved aerated concrete or lightweight aggregate concrete with open structure
This European standard specifies the procedure for the determination of the longitudinal long-term strains (creep strains) of test specimens taken from prefabricated components of autoclaved aerated concrete (AAC) or lightweight aggregate concrete with open structure (LAC) according to EN 1520 due to a constant compression stress sustained over a long period of time.

Overview
EN 1355:1996 is a CEN European standard that defines the test procedure for measuring long-term longitudinal deformation (creep strains) in autoclaved aerated concrete (AAC) and lightweight aggregate concrete with open structure (LAC). The standard covers the determination of creep strains in test specimens taken from prefabricated components (as referenced by EN 1520) when subjected to a constant compressive stress over an extended period. This measurement supports assessment of long‑term performance and serviceability of AAC and LAC elements in construction.
Key Topics
- Scope and applicability: Focused on prefabricated AAC and LAC components; applies when evaluating long‑term compressive creep.
- Test specimens: Use of specimens extracted from prefabricated components in accordance with EN 1520 (prefabrication reference).
- Loading conditions: Measurement under a sustained, constant compression stress to simulate long-term service loading.
- Longitudinal creep measurement: Determination of long-term strains (creep) in the axial/longitudinal direction of specimens.
- Data reporting and interpretation: Requirements for documenting creep behaviour to support design, quality control, or research (format and detail defined by the standard).
- Classification and context: Falls within concrete and concrete products standards (ICS 91.100.30) and is intended for consistent, comparable creep data across laboratories.
(EN 1355:1996 is also reproduced in national implementations such as SIST EN 1355:2001.)
Applications
- Assessing long-term deformation and serviceability of AAC and LAC structural or non‑structural prefabricated elements.
- Providing validated creep data for structural design checks, deflection estimates, and durability assessments.
- Quality control and type testing for precast AAC and LAC manufacturers to demonstrate product performance over time.
- Research and comparative testing in materials science and concrete technology studies focusing on lightweight and porous concrete types.
Who Uses This Standard
- Manufacturers of autoclaved aerated concrete (AAC) and lightweight aggregate concrete (LAC) prefabricated products.
- Independent testing laboratories performing long-term compression tests and creep measurements.
- Structural and materials engineers who require creep data for design and serviceability calculations.
- Certification bodies, product conformity assessors, and building authorities evaluating long-term behaviour of concrete products.
- Researchers studying time‑dependent deformation of porous and lightweight concretes.
Related Standards
- EN 1520 - referenced for prefabricated component sampling and preparation.
- Other CEN concrete testing standards and national implementations (e.g., SIST EN 1355:2001) for harmonized testing practice.
