What is BS EN 1097-7 - Determination of particle density of filler by pyknometer method about?
BS EN 1097 is a European Standard on tests for mechanical and physical properties of aggregates. The main aim of the BS EN 1097 series is to provide best industry guidance to ensure construction materials contribute to the structural integrity of civil engineering works.
BS EN 1097-7 is the seventh part of the BS EN 1097 series that describes the reference method used for type testing and in cases of dispute for the determination of the particle density of filler by means of a pyknometer.
For other purposes, in particular, factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established.
Who is BS EN 1097-7 - Determination of particle density of filler by pyknometer method for?
BS EN 1097-7 on the determination of the particle density of filler is useful for:
- Construction materials manufacturers and suppliers
- Manufacturers of bituminous binder and aggregates
- Mineral materials and products manufacturers
- Construction industry
- Civil engineers
- Contractors
- Cement production companies
- Quality control and testing authorities
Why should you use BS EN 1097-7 - Determination of particle density of filler by pyknometer method?
The pyknometer method is a well-known method for determining the volume of irregularly formed samples, e.g., aggregate. When the mass of the sample is known, the density can be calculated. The shape and density of aggregate particles can have significant impact on creating a denser mixture and improving the cohesion of asphalt binder and the stability of the mixture.
In this regard, BS EN 1097-7 provides the requirements for apparatus, reagents, test preparation and test procedure to evaluate the particle density of filler.
As a result, if you are a manufacturer of aggregates, testing in compliance with BS EN 1097-7 can demonstrate the performance and credibility of your products. The value of particle density can help determine variations of softening point, voids content in dry compacted filler and for proportioning asphalt mixture content.
By determining the particle density of filler, you can ultimately assess whether your construction materials are fit for use. Moreover, this assessment can also play a significant role in improving the design mix for optimal concrete performance.
