What is BS EN 933-8 - Sand equivalent test of aggregates about?
BS EN 933 is a series of the European standard on aggregates used in construction to give asphalt and concrete mass and strength.
BS EN 933-8 is the eighth part of the BS EN 933 series of documents that describes the reference method used for type testing and in case of dispute for the determination of the sand equivalent value of 0/2 mm fraction (for 0/4 mm, see Annex A) in fine aggregates or all-in aggregates.
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 933-8 - Sand equivalent test of aggregates for?
BS EN 933-8 on geometrical properties of aggregates is useful for:
- Civil engineers
- Builders
- Manufacturers of aggregates
- Quality control personnel
Why should you use BS EN 933-8 - Sand equivalent test of aggregates?
The sand equivalent test is used to qualify aggregates for applications where sand is desirable but fines and dust are not.
BS EN 933-8 provides the requirements on reagents and laboratory apparatus used to test sand value in fine aggregates.
BS EN 933-8 describes the preparation and procedure of test specimens to obtain two subsamples using graduated cylinders.
The calculation, expression of results and test report on sand equivalent value in fine aggregates are set out in BS EN 933-8.
Furthermore, BS EN 933-8 walks you through the aggregate sand equivalent test, which quantifies the relative abundance of sand in order to obtain a good grade aggregate that will reduce future maintenance and deliver a quality completed product.
As a result, the aggregate test is necessary to determine material quality based on gradation, fines content, and plasticity in order to improve construction materials and decrease maintenance.
