Can autoclaved fly ash bricks be used to build inspection wells?

No, autoclaved fly ash brick can't be used to drill water wells, because autoclaved fly ash brick is a lightweight brick with high water absorption rate, but its strength will decrease when it meets water, and quality problems will occur. Therefore, autoclaved fly ash bricks cannot be used in places with water, which is stipulated in the construction specifications. Autoclaved fly ash brick can only be used for relatively dry non-bearing walls.
