Overview
EN 772-11:2011 is a European Standard developed by CEN that defines test methods for determining the water absorption properties of various masonry units. It specifically covers aggregate concrete, autoclaved aerated concrete, manufactured stone, natural stone masonry units, and clay masonry units. This standard focuses on measuring the water absorption due to capillary action and the initial rate of water absorption, which are critical factors affecting the durability and performance of masonry in construction.
Water absorption by masonry units affects properties like frost resistance, structural integrity, and thermal insulation. By standardizing the method to measure absorption, EN 772-11:2011 ensures consistency in quality assessment and aids in selecting masonry materials suitable for diverse environmental conditions.
Key Topics
Scope
Specifies procedures for:- Determining the water absorption coefficient by capillary action for aggregate concrete, autoclaved aerated concrete, natural stone, and manufactured stone masonry units
- Measuring the initial rate of water absorption for clay masonry units
Test Principle
After drying specimens to a constant mass, a specific face is partially immersed in water. The increase in mass over a defined period indicates water absorption via capillarity or initial absorption rate.Specimen Preparation
Includes sampling minimum six specimens, drying at controlled temperatures (70 °C for concrete and stone units, 105 °C for clay units), and cooling prior to testing.Apparatus Requirements
Key equipment includes trays for water immersion, supporting devices to avoid contact with the tray base, precise weighing instruments, and ventilated ovens with temperature control.Calculation Formulas
Separate formulas are provided to calculate:- The capillary water absorption coefficient for various masonry types (expressed in g/(m²·s) or g/(m²·s^0.5))
- The initial rate of water absorption for clay units (expressed in kg/(m²·min))
Reporting
Test reports must include standard references, specimen descriptions, individual and average absorption results, soaking times, and any deviations or remarks.
Applications
Quality Control for Masonry Units
EN 772-11:2011 is essential for manufacturers and testing laboratories to evaluate the water absorption characteristics, ensuring masonry units meet durability requirements.Material Selection and Specification
Architects and engineers use absorption data to specify appropriate masonry units for projects, especially in climates where water penetration poses risks.Compliance with Building Codes
The standard supports compliance with European and national regulations related to masonry performance and weather resistance.Research and Development
Facilitates innovation in masonry materials by providing a benchmark for testing new products like autoclaved aerated concrete and manufactured stone.
