Can we make foam concrete without fly ash?

 

[Ramesh Doddi]

Obviously yes! One of my batchmates has done it.

 

[Dnyan Deshmukh]

Yes its possible to make foam concrete using materials other than flyash.
its a matter of economics and capacity of spending for replacing flyash in foam concrete.

The cheapest cementicious material is fly ash only.
