EN 480-11 Concrete - Additives for Mortar and Screed - Test for Determination of Air Void Properties in Hardened Concrete

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 480-11 test. This European Standard defines a test method for determining the air void structure in a hardened concrete sample containing entrained air.

The air gap structure is defined by the following parameters:

• Total air content;
• The specific surface of the air gap system;
• Space factor;
• Air gap size distribution;
• Micro air content.

The purpose of this test method is to determine air void properties in cured concrete, including total air content, void factor, and specific surface. These properties are important in determining the durability and frost resistance of concrete.

The test method involves preparing a thin section of the concrete sample and then using an image analysis system to analyze the air voids found in that section. The system measures the size, shape and distribution of air voids and calculates the total air content, void factor and specific surface.

The testing method also includes the procedures for taking samples, preparing concrete samples, and performing image analysis. It is important to follow standard procedures closely to obtain accurate and reproducible results.

In general, the EN 480-11 standard provides a reliable and standardized method for determining the air void properties in hardened concrete necessary to ensure the quality and durability of concrete structures.
