BS ISO 20290-1:2021 PDF Download

ISO 20290-1 is a standard that outlines the test methods for determining the mechanical and physical properties of aggregates used in concrete. Specifically, it focuses on the determination of bulk density, particle density, particle mass-per-volume, and water absorption. This standard provides procedures for measuring these properties using different methods, such as the hydrostatic balance method and the pycnometer method.

The target audience for ISO 20290-1 includes manufacturers of concrete and builders. It is beneficial for these stakeholders as it allows them to assess the quality and suitability of aggregates for use in concrete. Aggregates are essential in concrete, as they contribute to its compressive strength, workability, durability, and ability to receive finishes. By following the test methods outlined in ISO 20290-1, manufacturers and builders can ensure that the aggregates they use meet the necessary criteria for these properties.

The standard is significant as it provides a comprehensive and standardized approach to assess the characteristics of aggregates for concrete. It offers test methods to determine the loose or compacted bulk density of dry or moist aggregates, as well as the particle density and water absorption. These measurements are crucial in understanding the physical and mechanical properties of aggregates, which directly impact the performance and longevity of concrete structures.
