What is BS EN 1744-3 - Preparation of eluates by leaching of aggregates about?
BS EN 1744 is a European Standard for testing the chemical properties of aggregates. The main of the BS EN 1744 series is to provide the best industry guidance to ensure construction materials contribute to the structural integrity of civil engineering works.
BS EN 1744-3 is the third part of the BS EN 1744 series that specifies a method for the preparation of eluates, by leaching of aggregates, for subsequent investigation of physical and chemical properties by existing standard methods for the purpose of compliance testing.
BS EN 1744-3 applies to unbound aggregates that have a particle size below 32 mm with or without size reduction.
Who is BS EN 1744-3 - Preparation of eluates by leaching of aggregates for?
BS EN 1744-3 on the preparation of eluates by leaching of aggregates is useful for:
- Construction materials manufacturers and suppliers
- Manufacturers of mineral materials and products
- Manufacturers of aggregates
- Cement and concrete industry
- Civil engineers
- Contractors
- Quality control and testing authorities
Why should you use BS EN 1744-3 - Preparation of eluates by leaching of aggregates?
The leaching of aggregate is a decisive parameter to fundamentally understand and determine when the environmental impact on soil and groundwater is assessed in the short and long term.
BS EN 1744-3 details on the preparation of eluate which is a solution remaining after the laboratory leaching procedure of solid material in contact with a leachant. The properties of the eluate are measured using methods developed for water analysis adapted to the analysis of eluates.
In this regard, BS EN 1744-3 specifies the reagents and apparatus needed and the test sampling, preparation and testing procedures for the preparation of eluates by leaching of aggregates.
As a result, if you are a manufacturer of aggregates, conforming to BS EN 1744-3 can demonstrate the performance and quality of your products.
Moreover, the chemical composition of construction materials and their leaching behaviour is crucial for the environmental compatibility of a product.
