Why Choose BS ISO 22904:2020?

The use of additions in concrete is a critical aspect of modern construction practices. Additions can significantly enhance the properties of concrete, making it more adaptable to various environmental conditions and structural requirements. The BS ISO 22904:2020 standard provides a clear framework for selecting and using these additions effectively.

Benefits of Using Additions:

• Improved Durability: Additions can enhance the resistance of concrete to environmental factors such as moisture, temperature fluctuations, and chemical exposure.
• Enhanced Strength: By optimizing the composition of concrete, additions can increase its compressive and tensile strength, making it suitable for a wider range of applications.
• Sustainability: Many additions are derived from industrial by-products, contributing to more sustainable construction practices by reducing waste and conserving natural resources.

Comprehensive Guidance

The BS ISO 22904:2020 standard provides detailed guidance on the types of additions that can be used in concrete, including:

• Mineral Additions: Such as fly ash, silica fume, and slag, which can improve the workability and long-term performance of concrete.
• Chemical Additions: Including superplasticizers and air-entraining agents, which enhance the fluidity and freeze-thaw resistance of concrete.

Each type of addition is discussed in terms of its properties, benefits, and potential applications, providing users with the knowledge needed to make informed decisions about their use in specific projects.

Who Should Use This Standard?

The BS ISO 22904:2020 standard is an invaluable resource for a wide range of professionals, including:

• Structural Engineers: To ensure that concrete structures are designed to meet the highest standards of safety and performance.
• Construction Managers: To oversee the implementation of best practices in concrete mixing and application.

This document specifies requirements for the properties for silica fume, siliceous fly ash and ground granulated blastfurnace slag for use as a type II addition for production of concrete conforming to ISO 22965. Additions according to this document can also be used in mortars and grouts.

This document applies to the silica fume which is a by-product of the smelting process used to produce silicon metal and ferro-silicon alloys.

Fly ash produced with other types or higher percentages of co-combustion materials than those provided for in this document is outside the scope of this document.

Ground granulated blastfurnace slag containing any added materials other than grinding aids and/or gypsum (calcium sulfate) is not within the scope of this document.

It is not within the scope of this document to specify provisions for the practical application of additions in the production of concrete, mortar or grout, i.e. requirements concerning composition, mixing, placing, curing, etc.
