What is BS EN 1097-3 - Determine loose bulk density and voids of aggregates 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 the best industry guidance to ensure construction materials contribute to the structural integrity of civil engineering works.
BS EN 1097-3 is the third part of the BS EN 1097 series that specifies the test procedure for the determination of the loose bulk density of dry aggregate and the calculation of the voids.
The test is applicable to natural and artificial aggregates up to a maximum size of 63 mm.
A method for the determination of the apparent (bulk) density of filler in kerosene is given in annex A.
Who is BS EN 1097-3 - Determine loose bulk density and voids of aggregates for?
BS EN 1097-3 on determining loose bulk density and voids of aggregates 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 1097-3 - Determine loose bulk density and voids of aggregates?
Aggregates have a significant impact on concrete strength since they produce the majority of the total concrete volume. As a result, when aggregates are used in construction, the measure of their loose bulk density, particle density, and voids is crucial.
The dry mass of aggregates filling a specified container is determined by weighing and the corresponding loose bulk density is calculated. The percentage of voids is calculated from the loose bulk density and the particle density.
In this regard, BS EN 1097-3 provides the requirements for apparatus, test preparation and test procedure to evaluate the loose bulk density and voids of aggregates.
As a result, if you are a manufacturer of aggregates, testing in compliance with BS EN 1097-3 can demonstrate the performance and credibility of your products.
By determining the loose bulk density and voids of aggregates, 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.
