[Dnyan Deshmukh]

Practically you can use anything in concrete by doing designing and checking for desired requirements through trials.

You need to check it by doing trial concrete for is rice husk hash do chemically affecting the foaming agent properties. If its not affecting the foaming agent properties such as ensuring bubbles formed were not broken till concrete is set.

If its breaking the bubbles, the voids will not form, if it does not affect it, you can produce foam concrete with ricehusk ash.
