**What is BS EN 14227-3 - Fly ash bound granular mixture specifications about?**

Fly ash is used in mixtures because the spherical shape of fly ash particles helps to facilitate the movement of concrete. BS EN 14227 is a European Standard series that discusses specifications for hydraulically bound mixtures.

BS EN 14227-3, the third part of the multi-series, provides specifications for fly ash bound granular mixtures for roads, airfields, and other trafficked areas, and specifies the requirements for their constituents, composition, and laboratory performance classification.

In BS EN 14227-3, fly ash refers to siliceous or calcareous fly ash complying with EN 14227-4. Note: Where fly ash is part of cement conforming to EN 197-1 or hydraulic road binder conforming to EN 13282-1 and EN 13282-2, then reference should be made to EN 14227-1 or EN 14227-5 respectively.

**Who is BS EN 14227-3 - Fly ash bound granular mixture specifications for?**

BS EN 14227-3 on fly ash bound granular mixtures specifications is useful for:

Manufacturers and suppliers of hydraulically bound mixtures
Equipment suppliers
Suppliers of binders such as cement, fly-ash needed to make hydraulically bound mixtures
Contractors and infrastructure developers
Construction, civil and design engineers
Road maintenance authorities
Inspection and quality assurance personnel

**Why should you use BS EN 14227-3 - Fly ash bound granular mixture specifications?**

The addition of fly ash to concrete increases the workability of flexible concrete as well as the strength and durability of hardened concrete. The usage of fly ash is also cost-effective. The quantity of portland cement used in concrete may be lowered when fly ash is added.

BS EN 14227-3 provides you with guidance on constituents such as cement, fly ash, granulated blast furnace slag, hydraulic road binder, lime, soil, water, and other constituents, ensuring hardness and structural stability of fly ash bound granular mixtures.

BS EN 14227-3 provides you with guidance on constituents, mixture, requirements for the fresh mixture, laboratory mechanical performance classification, production control, designation, and description, ensuring the quality and performance of fly ash bound granular mixtures.

The adoption of BS EN 14227-3 allows you to standardize the requirements for fly ash-bound granular mixtures, ensuring cost-effectiveness and limiting the environmental impact on roads, airfields, and other trafficked areas.
