Aggregates — Determination of the Petrographic Index of the Sulfatic Swelling Potential of Granular Materials — Test Method to Be Used for the Evaluation of the Petrographic Index of the Swelling Potential.

This document sets out the test method for determining the swelling potential petrographic index (SPPI) and recommends chemical analyses that are to be performed when required. It aims to evaluate the sulphate swelling potential of materials sold by aggregate producers for use as backfill under non-structural concrete slabs inside new buildings (residential, commercial or industrial) or for the renovation of those structures. The test method applies to dense-graded material and clear stone found in quarries or from gravel pits or sandpits. The test method may be used in conducting appraisals of existing buildings, but should not be used indiscriminately as a criterion for replacing materials in an existing building.
