BS EN 480-15:2013 PDF Download

BS EN 480-15:2013 is a standard that provides guidelines for testing viscosity modifying admixtures in concrete, mortar, and grout. The standard specifies the materials, composition, and mixing procedure to produce a reference concrete with a prescribed consistency and segregated portion. This reference concrete is used as a benchmark for testing the effectiveness of viscosity modifying admixtures.

The standard also outlines the process for determining the requirements of the test mix in comparison with a control mix. This allows for a systematic evaluation of the performance of the admixture in terms of its impact on the viscosity, workability, and flow characteristics of the concrete. By conducting these tests, the standard helps to ensure that viscosity modifying admixtures meet the necessary quality and performance standards for use in concrete construction.
