AS 3583.6:2018 PDF Download

AS 3583.6:2018 is a standard that provides guidelines for testing supplementary cementitious materials, specifically fly ash and slag, to determine their relative water requirement and strength index. The standard includes a reference method for determining the relative water requirement, which is the amount of water needed to achieve a desired consistency in the cementitious material. Additionally, the standard outlines two methods for determining the strength index of fly ash and slag.

The first method described in the standard is the standard test, which measures the strength of the cementitious material over a certain period of time. This provides an indication of the material's ability to develop strength over time. The second method is an accelerated test, which allows for a faster determination of the strength index. This method is useful when there is a limited time available for testing or when a quicker assessment of the material's properties is required.
