Question of the day
Test yourself in 10 seconds
One question a day keeps exam stress away. Pick an answer to check it.
As per IS 3812 (Part 1): 2013, which ash is prepared from fly ash or bottom ash conveyed in dry form and deposited dry?
Answer: A. Mound ash
IS 3812 (Part 1): 2013 defines Mound ash as ash prepared from fly ash, bottom ash, or a combination of both, in any proportion, that is transported and deposited strictly in the dry state. This distinguishes it from Pond ash, which is transported in slurry form and deposited wet. Mound ash is typically used for engineered fill or land reclamation.
