AS 3583.3:1991 (R2016) PDF Download

AS 3583.3:1991 (R2016) is a standard that provides a method for testing the loss on ignition (LOI) of supplementary cementitious materials used in conjunction with Portland cement. The LOI of these materials refers to the amount of weight lost when the materials are heated to a high temperature, usually around 950 degrees Celsius.

The standard outlines the procedure for conducting the LOI test, which involves weighing a sample of the supplementary cementitious material and heating it to the specified temperature. The weight loss due to the evaporation of volatile compounds is then recorded. This test is important because it provides information about the organic content and the amount of carbonates present in the material, which can affect its performance in cementitious applications.

The results of the LOI test can be used to evaluate the purity and composition of the supplementary cementitious material, and to assess its compatibility with Portland cement. This information is crucial for determining the suitability of the material for use in cement formulations and concrete production.
