Lastly, the dust content was reported to be ranging from 8.20 to 36.5%. The water absorption of QD is comparatively higher than NRS due to the higher fines content (particle sizes <75 µm), while, the specific gravity of the QD is similar to the NRS. The particle size distribution of QD obtained from the past findings was summarized in Table 12.2.

Is quarry dust suitable for block work?
That depends upon what the quarry dust is. If it has minerals that will react with the cement you could get a faster or slower set time. Also, since quarry dust is quite fine, you should have a denser concrete. Higher density can mean less water penetration. The fine quarry dust particles will require more water to wet the greater surface area.
