We have many standards and method for determination of water absorption of the cement paste, mortar and concrete. Is there the standard for determination of water absorption the powder such as fly ash?
What is the difference between the amount of moisture content (%) and water absorption (%) of powders such as fly ash or pozzolan materials?
In ASTM C618 &Table 1: Moisture content, max for fly ash class N, F and C is 3%.
Though, we can use ASTM C311-13, procedure No.11 and No.12 for calculation of Moisture content.
Is there any the standard for determination of water absorption of the powder such as fly ash or pozzolan materials?
maybe this can help you:
Standard 18847-84 (Russian language) Unmoulded loosed refractories. Methods for determination of water absorption, apparent density and open porosity of grain materials.

Dear Thanh Qui Duong
Thank you so much, did you do this testِ (water absorption of powder)
Sorry Hossein, could't find anything in the German DIN standards specifically on fly ash powder and water absorption.
Regards,
Martin
