AS 3582.1:1998 PDF Download

AS 3582.1:1998 is a standard that establishes the requirements for the use of fly ash as a supplementary cementitious material in the production of concrete and mortar. The standard provides guidelines for the composition and physical properties of fly ash that make it suitable for use in conjunction with Portland cement or blended cement.

The standard emphasizes the importance of ensuring the quality and consistency of fly ash to ensure its proper performance in concrete and mortar mixtures. It specifies the minimum and maximum limits for various chemical and physical properties of fly ash, such as its fineness, carbon content, and loss on ignition. These requirements help ensure that fly ash contributes to the desired strength, durability, and workability characteristics of the cementitious materials.

In addition, the standard includes an appendix that presents alternative methods for assessing the compliance of fly ash with the specified requirements. These alternative methods can be used as an alternative to the standard testing procedures, providing flexibility and options for evaluating the suitability of fly ash from different sources.
