What is EN ISO 10390:2013?

EN ISO 10390:2013 is a technical standard that specifies the method to determine the aggregate crushing value (ACV) of coarse aggregates. This standard is commonly used in the construction industry to measure the durability and strength of aggregates used in concrete production.

Testing Procedure and Equipment

The testing procedure outlined in EN ISO 10390:2013 involves subjecting the coarse aggregate sample to a specified load and determining its resistance to crushing. The equipment used for this test includes a compression machine, sieves, cylinders, metal plates, and a balance for weighing the samples.

Significance of Aggregate Crushing Value

The aggregate crushing value provides an indication of the strength of the aggregate material and its ability to resist crushing under compressive loads. It helps in assessing the suitability of aggregates for use in construction projects such as road pavements, concrete structures, and railway ballast. The lower the ACV value, the stronger the aggregate material.

Interpretation of Test Results

The results obtained from the aggregate crushing value test can be interpreted as follows:

If the ACV value is within the specified limit for a particular application, it indicates that the aggregates are suitable for use in that specific construction project.

If the ACV value exceeds the recommended limit, it suggests that the aggregates may not provide adequate strength and durability for the intended application, and further testing or a change in aggregate source may be necessary.

In conclusion, EN ISO 10390:2013 is a crucial standard in the construction industry for evaluating the durability and strength of coarse aggregates. By determining the aggregate crushing value, compliance with quality standards can be ensured, leading to safer and more reliable construction projects.
