BS EN 1744 is a European Standard on tests for chemical properties of aggregates. The main aim of the BS EN 1744 series is to provide the best industry testing methods to ensure construction materials contribute to the overall structural integrity of civil engineering works.
BS EN 1744-1 is the first part of the BS EN 1744 series that specifies procedures for the chemical analysis of aggregates.
BS EN 1744-1 specifies the reference procedures and, in certain cases, an alternative method that can be considered as giving equivalent results.
BS EN 1744-1 describes the reference methods used for type testing and in cases of dispute (and
alternatives methods) for chemical analyses of aggregates.
For the purpose of type testing and in cases of a dispute only the reference method should be used.
BS EN 1744-1 on testing chemical properties of aggregates is useful for:
The chemical characteristics of the aggregate are believed to be a significant factor in determining the strength of the asphalt-aggregate bond.
In this regard, BS EN 1744-1 provides the requirements of reagents, apparatus, sampling and preparation of aggregate test specimens as well as the test procedure to calculate the loss on ignition.
The test methods used to determine various chemicals in aggregates are specified in BS EN 1744-1 may be used for factory production control, audit tests and for type tests.
As a result, if you are a manufacturer of aggregates, conforming to BS EN 1744-1 can help demonstrate the presence of adequate and required chemical properties of your products, such that they contribute to the stability, workability and enhanced performance of cement and concrete for your projects.
