Overview

The BS ISO 20290-3:2019 standard is an authoritative document that outlines the test methods for determining the aggregate crushing value (ACV) of aggregates used in concrete. The ACV is a crucial parameter that indicates the strength and durability of aggregates, which are fundamental components of concrete. By adhering to this standard, professionals can ensure that the aggregates used in their projects meet the necessary quality requirements, leading to safer and more reliable concrete structures.

Why is the Aggregate Crushing Value Important?

The Aggregate Crushing Value (ACV) is a measure of the resistance of an aggregate to crushing under a gradually applied compressive load. It is a critical parameter that helps in assessing the strength and durability of aggregates. A lower ACV indicates a stronger aggregate, which is less likely to break down under load, thus contributing to the overall strength and longevity of the concrete structure.

Applications

This standard is applicable to a wide range of construction projects, including:

• Highway and road construction
• Bridge and overpass construction
• Residential and commercial building projects
• Infrastructure development

By following the guidelines set out in BS ISO 20290-3:2019, engineers and construction professionals can ensure that the aggregates used in their projects are of the highest quality, leading to safer and more durable structures.

Benefits of Using BS ISO 20290-3:2019

Adopting the BS ISO 20290-3:2019 standard offers numerous benefits, including:

• Quality Assurance: Ensures that aggregates meet the necessary quality standards, leading to stronger and more durable concrete.
• Consistency: Provides a consistent methodology for testing aggregates, ensuring reliable results across different projects and locations.
• Safety: By using high-quality aggregates, the risk of structural failure is minimized, enhancing the safety of the construction.
• Cost-Effectiveness: Reduces the likelihood of costly repairs and maintenance by ensuring the use of durable materials from the outset.

Who Should Use This Standard?

The BS ISO 20290-3:2019 standard is an invaluable resource for a variety of professionals, including:

• Civil engineers
• Construction managers
• Materials testing laboratories
• Quality assurance professionals
• Aggregate suppliers

By incorporating this standard into their practices, these professionals can ensure that their projects meet the highest standards of quality and safety.

BS ISO 20290-3:2019

This standard BS ISO 20290-3:2019 Aggregates for concrete. Test methods for mechanical and physical properties is classified in these ICS categories:

• 91.100.30 Concrete and concrete products

This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load.

The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve. For other size fractions, a recommended method is described in Annex A. The aggregate size fraction taken for this test can also be as per the relevant national standards.

The method is not suitable for testing aggregates with an aggregate crushing value higher than 30. In such cases, the method described in ISO 20290-4 is applicable.
