Several countries have specifications for additions that are used in concrete, such as fly ash (pulverised fuel ash) or other pozzolans and virtreous blast-furnace slag, shile other countries are preparing specifications for such materials. This paper lists the more important existing specifications and summarises, compares and discusses their specific requirements. The differences and similarities of nomenclature, requirments and methods of test are indicated. Attention is given to the relationship between the results obtained from a test and the materials performance in use. Specificaiton test results may not always be valid criteria for forecasting the performance of a material.
